We stood on the edge of a crusty mud puddle and tapped its edge with our foot. Waves formed in the mud like a waterbed, causing a few open spots to gurgle. But this wasn’t just any mud puddle. We were actually standing on the crater of a mud volcano in Azerbaijan. One of the most unusual things to do when visiting Baku is to see Gobustan’s mud volcanoes and prehistoric petroglyphs. We’ll show you how you can see them too and what to expect.

There are over 350 mud volcanoes spread across this region of Azerbaijan. These are not volcanoes in the typical sense, but are insead mud volcanoes. As gases are released in the Earth’s crust, they push up through thick layers of mud on the surface. The result is mud and sediments are forced through fissures as the gas bubbles spout out. The bubbles eventually spill over the edge and form cones or flat spheres of mud.

Mud volcanoes are usually a good indication of petroleum in the ground. As it happens, oil and natural gas are huge industries in Azerbaijan, they used to be the largest producer in the world. We saw a lot of drilling in the area as well as right in the city of Baku.

In addition to the mud volcanoes, there are said to be 140 submarine volcanoes in the Caspian Sea.

There are a couple of ways to see the mud volcanoes, the first is the national museum. Just south and west of Baku there are thousands of mud volcanoes. The government recently opened a complex to preserve some of these natural phenomena. Called Mud Volcanoes State Nature Reserve, there are 43 mud volcanoes in the park, but not all are accessible.

The main one to see is called the Gilinj (Sword). It is a string of 8 small to medium sized active cones up to 10-15 metres tall. In other areas they are known to be as much as 200-500 m high.

A boardwalk allows you to walk beside the cones, but you can not get very close. Even from a distance this natural wonder makes quite a spectacle. There is evidence that they have been active since the Pleistocene Era, between 770,000 and 126,000 years ago.

The mud volcanoes don’t have large eruptions, but they sputter and bubble frequently.

The surrounding landscape is very arid and looks as though it is stuck in prehistoric times. The grey mud volcanoes stand out against the ochre coloured land.

Tip – There’s a museum at the Mud Volcano Complex but it is very odd. It mostly has displays of skeletons from animals in Azerbaijan and around the world. There is no information on mud volcanoes in the museum, which is what we had expected and wanted to see.

Entrance fee – 15 AZN (€7.50); Hours – 10am-8pm

In addition to the museum, our taxi driver took us onto private land so we could get an up-close view of a few other mud volcanoes. We approached the cones from below and could see mud slowly trickle down from the top. These mud flows slowly build up until cones are formed.

On Google maps the one was saw is called “Mud Volcan Big’. We’ve included it on our map at the bottom of the post.

We walked to the top of a small volcano to find a number of mud puddles. It was here that we experienced something new. By gently tapping a foot on the mud puddle’s crusty edge, we caused a cascade of waves. They extended from the crust to the liquid centre and reminded us of a waterbed. After a few seconds, bubbles began popping up in the mud.

We stuck our fingers in one puddle and the mud was surprisingly cold and thick. Apparently some people get right in the puddles to cover their entire bodies in mud.

Visitors usually see one or the other; the complex or random volcanoes. We saw both and are glad we did. The complex has at least a dozen volcanoes of all different sizes, but you can only view them from a boardwalk platform. The wild volcanoes are also interesting, and you can walk right up to them, stick you hand in them and maybe even take a mud bath. But, which one you go to is up to the driver and there are hundreds to choose from.


Walking through a jumble of massive boulders, under overhanging cliffs and beside caves, it was easy to imagine Paleolithic humans living here. And in fact, they did. As much as 40,000 years ago humans lived among these rocks and left us their art as gifts. Not far from Baku, a series of caves and rock walls have many examples of petroglyphs left by these people thousands of years ago. Researchers believe the people were drawn to this area because it was on the main migration route travelled by prehistoric man.

Note – it is often referred to as Gobustan Prehistoric Rock Art.

We walked between the large boulders in search of the rock art. They turned out to be remarkably easy to find. The petroglyphs included depictions of aurochs (extinct bovine), horses, onangers (wild ass), deer, antelope, people and many more. There are a staggering 6,000 images on 1,000 rocks in this one complex.

We spent hours in these rocks, amazed at the sheer number of petroglyphs we saw. When looking at them, we had to remind ourselves of the crude tools tools used by these artists and storytellers.

Some walls have many petroglyphs that are carved over top of others, making it difficult to distinguish any one in particular. Archaeologists aren’t sure why this was done, but believe that each layer was carved dozens, if not hundreds, of years apart. These layers only occurred on a few walls, but in those places, there were many layers. Researchers believe this suggests something unique about the wall.

In addition to the ones we can easily see above ground, much older petroglyphs were found on cave walls below ground level. It is assumed they are much older and were covered over eons of change in the land. It’s no surprise that this site is a UNESCO World Heritage Site.

In addition to the petroglyphs, other remnants from these prehistoric people can be found below the cliffs. In one area, several holes had been sculpted into the rock. They are called Cup Marks and had different uses. Some collected rain water or stored sacrificial blood. Others were used to prepare meals.

There were even two musical instruments, called Galvadash. They were large slabs of varying thickness that produce different tones when tapped on with a stone. 

The museum at the site has excellent information on Paleolithic man and of their rock art. It is worth visiting the museum before going up to the rock art location.

Entrance fee – 10 AZN (€5); Hours – 10am-5pm

  • If you are visiting on your own, be aware that there are two Gobustans on Google Maps. The more southern one is where you want to go. It is also spelled Qubustan. On Google Maps the Petroglyphs are listed as ‘Gobustan Rock Art Cultural Landscape’. Mud Volcanoes State Nature Reserve is labelled as ‘The Mud Volcanoes Tourism Complex’. They are both marked in the map below.
  • The petroglyphs are located on a hill 1.9 km from the museum so most people hire a local taxi. If you hired a driver for the day, then it will drive you to the site. You can also walk, but it is uphill. It is silly that the museum was not built closer to the site. This set-up makes it more difficult for the independent traveller.
  • There is no protection from the strength sun at any of the sites so use sunscreen, wear a hat, bring plenty of water. There is a cafeteria at both museums.

The easiest way to get to these sites is to take a group or private tour. There are many offered in Baku’s Old City. It is possible to go on your own, which is what we did, but it is more complicated and the taxi touts make it more exasperating. Take Bus 195 to Gobustan town centre. From there, take a taxi to both the rock art site and the mud volcanoes. Or, you can take a Yango/Bolt or taxi from Baku to Gobustan State Historical and Cultural Reserve (Rock Art). There are local 4×4 taxis on the highway in front of the museum that will take you to a private mud volcano and/or the government complex. We did not see taxis at the Mud Volcanoes State Nature Reserve so recommend going to the Rock Art site first.

If you hire a local 4×4 taxi you must be clear that you want to go to the government museum or see random mud volcanoes suggested by the taxi driver, or both. The government complex has a fee and most taxi drivers would rather take you in their beat up 4WD Lada to one of of the many mud volcanoes in the area. The exasperating part is bargaining with them.

Mud Volcano Complex, Rock Art Museum and Mud Volcano Big (that we visited) are the lowest points on the map below. Click on the image for an interactive map.


This is another unique Azerbaijani attraction. In a land where petroleum has always been close to the surface, gas used to frequently seep above ground. In these spots spontaneous flames would spark and burn for many years, some, for thousands of years. Modern oil wells have decreased these flames, but just north of the city you can see one.

Yanar Dag (Burning Mountain) is an ‘eternal’ flame on a hill above the city. Some theories say it has been burning since Zoroastrian times, thousands of years ago. Another story says the fire was started in the 1950s by a discarded cigarette and has been burning ever since. Regardless how old did is, Yanar Dag is an unusual thing to see.

Apparently there used to be many eternal flames in this region. Seeing one makes it a bit easier to understand why the Zoroastrian’s thought fire was a manifestation of their divinity. We saw other Zoroastrian sites in Wakhan, Tajikistan as well as Ateshgah Temple in Baku.

Recently a complex was built around the eternal flame and made it more gimmicky. We’re glad we saw it because it is unusual, but keep your expectations in check so you’re not disappointed.

Entrance – 9 AZN; Hours – The website states it is open from 9am until 8pm, but it closed at 7 pm when we went. Since it is an outdoor flame, it is better to see it later in the day as opposed to under a strong sun.

The site is located 20 km from Icheri Sheher and while it can be accessed by a combination of metro and bus, they are very arduous. Yango/Bolt are reasonably priced options, but it is also included on many tours. To use public transport, take either bus 217 from Koroǧlu Metro Station or bus 147 from Azadliq Prospekti Metro Station.

    1. Thanks! They are fascinating.

  1. Given our limited time in the country, we opted to forego the natural wonders of the area in lieu of the cultural ones, so I’m glad to see these three places vicariously. Wild to see that mud move with your foot, and amazing how long those mud volcanoes have been around.

    1. They were much more interesting than I expected,especially when we started making waves and cauing bubbles. It helps to understand how ancient humans had so many wild beliefs about the underworld..

  2. Today’s photos remind me of the western U.S. and Yellowstone. They’re utterly fascinating.

    1. Similar, but these are cold, not hot, and much less regulated and protected which is too bad.

  3. OK, now Azerbaijan is on my list – well, it already was, but now I want to go more. I love geological features like this and had never heard of them. I am not too sure if I would want to get right in the puddles to cover my entire body in mud, but it certainly looks like an incredible sight to visit. Thanks for sharing, and have a good day 🙂 Aiva xx

    1. I was not at all tempted to hop in the mud, as it was my fingers where covered in thick mud for a while. 😊 We highly recommend Azerbaijain for a visit. Thanks Aiva! Maggie

  4. The world has some crazy places. The mud volcanoes remind me of the geothermal areas around Rotorua. We also saw some on White Island. As to the eternal flames, folks in the Cooking Lake area up here used to be able to light their tap water on fire. Scary if you don’t expect it. Thanks for showing us the sights Maggie. Happy Tuesday. Allan

    1. Yes similar to Rotarua, but these are cold, not thermal. The eternal flames make it a little easier to understand old beliefs. Crazy that it’s still happening in Alberta! Thanks Allan

  5. An almost primeval-looking landscape, and totally fascinating! I see what you mean about the likeness to a water bed, the movement seems very similar. The petroglyphs look amazing too, I’m sure like you I could spend ages searching them out and photographing them!

    1. It really is a fascinating area. So many strange and wonderful places with ancient histories and yet so close to the modern city. The petroglyphs were surprsingly easy to see, compared to others where we’ve had to search and still weren’t sure what we’re looking at. Tha ks Sarah

  6. Really places I would like to visit, so beautiful and interesting with the mud and the historical reserv.

    1. Thanks, they are really fascinating sites.

  7. Thanks a lot for sharing this post: I found it really fascinating.

    I had never heard of mud volcanoes, but I was very interested in them, so I did a little research and discovered that we have a few, little-known ones here in Italy, mainly near the Apennine mountain range, which crosses our country, from north to south.

    1. Well now you’ll have to go see the Italian ones and let all of your readers learn what you found!! 😊

      1. I think I’ll have to do that, sooner or later! 👍

  8. These are some of the things I want to see the most in Azerbaijan. Too bad the mud volcano museum was a disappointment, but seeing those petroglyphs up close is really neat. I looked up Yanar Dag on Google, and the entire place doesn’t look too big. The burning flames are cool though.

    1. Yanar Dag is quite disappointing. It’s only interesting because it’s an example of the fires that used to be everywhere. But Gobustan is definitely worth it. The petroglyphs were the highlight for us.

  9. I learn so much reading your blog. Mud volcanoes and permanent petroleum fires and petroglyphs. Everything an armchair traveller needs to make her day interesting.

    1. Glad to keep you entertained 😊

  10. ALL captivating sites! Time travelling back into the Paleolithic era was awesome. WOW! 🙂

  11. Wow, these all are completely fascinating! The rugged, otherworldly terrain seems like a great location for science fiction movies. Great post, Maggie!

    1. It would, or a caveman movie too. It ia very otherwordly. Thanks Tricia

  12. […] Gobustan’s Mud Volcanoes and Prehistoric Petroglyphs […]

  13. wonderful landscapes!

  14. The petroglyphs and mud volcanoes are fascinating, Maggie. I enjoyed watching your short video of the “water bed” effect. Amazing. Apparently this mud is good for your skin but like you, I don’t think I would want to get in it! And amazing how that region was a prehistoric crossroads. The people must have been eating and living well in order to have time to do their art.

  15. Fascinating landscapes of mud volcanoes!


  16. Maggie, you two find the neatest stuff.

  17. Fascinating post, it would be amazing to see them IRL

    1. Thanks, there are so many fascinating places to see around the city. The petroglyphs and mud volcanoes were favourites. Maggie


  18. A strange part of the world, Maggie. I assumed there would be an element of danger to the mud ‘volcanoes’, but apparently not. I’m more drawn to the petroglyphs (and that’s a terrible pun!) xx

  19. Very nice 👌

  20. I am shaking my head about my ignorance hereto as all of this is brandnew but absolutely fascinating for me. If this is how the area of the mud volcanoes looks above the ground . . what must the reality be below! Somewhat ‘wobbly’ surface area for the earth. Would love to see the petroglyphs as there are a number of areas in the North Australian wilderness where such ancient drawings have also been found. Thank you for the marvellous photo gallery!

    1. I know! Especially when we could jiggle the earth like that 😊 So many amazing things on this earth. Thanks Eha

  21. This is so interesting about mud volcanos Maggie. I am reminded of a recent story I saw about the dangerous Campi Flegrei volcano near Naples, Italy. So scary, but fascinating! 🗻🌄🌋

    1. These weren’t so scary because they won’t erupt, but very fascinating!! Thanks Kym

  22. What unusual visits. The mud volcanoes are so fascinating and I always like seeing petroglyphs, and imagining the people who drew them. Thanks, again, Maggie and Richard.

    1. The petroglyphs really intrigued us, partly because the setting made it easy to visualize prehistoric life. Thanks Karen

  23. Such a fascinating and unique landscape! X

    1. It is, and it will wait for you next year 😊

  24. The mud volcanoes remind me of the mud pools at Rotorua in New Zealand’s North Island – they’re the most bizarre thing. And yes, people relish in slathering mud all over, saying it’s amazing for the skin. You can buy mud masks for the face, so I guess there’s no difference.

    Yanar Dag is bizarre, but I’ve never seen an oil field. Great photos! Cheers, Nilla.

    1. I’ve been to the ones in NZ. Azerbaijan’s are not thermal and there are no geysers. I expected to find mud facials etc on Baku, but I didn’t notice any. Maybe I didn’t look hard enough. They’re also not as touristy as NZ, you can drive up to a number of them on almost any hill. Sorry if this is a repeat message, I sent another but wifi is awful and I don’t think it was sent.

  25. Fascinating. I didn’t know about this type of volcanoes…Great story and photos. (Suzanne)

  26. Amazing, aren’t they? We’ve seen some of these ourselves (as you might guess) but no matter how many you see, they never lose their ability to intrigue. You look at the bubbling mud and think, something weird is going on down there!

    1. They are. We’ve seen quite a few mud pools and thermal mud volcanoes but never a cold one before. The world is a strange and wonderful place 😊

  27. I am fascinated with these mud volcanoes and all the bubbling mud puddles. Interesting to hear that some people get right in there and cover their bodies in mud. Not sure that’s for me!

    1. They are quite fascinating, but there’s no way I’d get inside one! Thanks Linda

  28. Very cool Maggie! Thank you for sharing highlights of incredible nature and history. I would have spent hours in those rocks, too. 👍🏻

    1. Thanks Michele, seeing carvings made thousands of years ago was very special. You would love it too.

    1. They are! 😊 Thanks for your comment

  29. What a landscape – the mud volcanoes are weirdly inviting, and so intriguing to know what’s going on beneath the surface. The bolder fields and eternal flames are really unique too 🙂

    1. It’s a fascinating area with so much history and crazy landscapes so close to the modern city! Thanks Hannah

  30. Those mud volcanoes are amazing! What a strange and wonderful mix of natural science and beautiful landscape. I love all the petroglphs on the rocks- so interesting to think what stories they are telling with them.

    1. It’s really a fascinating area with mud volcanoes and prehisotoric rock art with in a few kilometers of each other. If they only knew that we’d be lookong at their art thousands of years later, I wonder what they’d think.

  31. Everything about this is fascinating! I’ve seen a couple mud volcanoes in Yellowstone, but they’re boiling hot and you can’t walk up to them or touch them. I was really surprised when you mentioned these ones were cold. And the way they ripple when you step near them is unexpected. It seems like your foot should just sink into the mud there. I wouldn’t have expected it to be solid yet flexible.

    1. It’s funny that they have the same name because they are quite different than the thermal mud volcanoes. We were completely surprised that we could make them ripple too!

  32. Everything about this place sounds odd and interesting. Those mud volcanoes – that the mud is cold, and people cover themselves with it! Thanks for showing how it moves in the little videos. I like the rock drawings, and it was interesting to see the natural flames of the gas, too. 🙂

    1. Haha, yes, odd and intereresting. That’s how we found it too 😊 The world is a wonderful place isn’t it?! Thanks for your comment.

  33. Fascinating!! I loved reading about these weird and wonderful natural wonders 🙂 The mud volcanoes are stunning and so cool. I was surprised the mud’s cold, you’d think it would be blisteringly hot. It’s so bizarre the museum at the Mud Volcano Complex features nothing about the volcanoes, they’re definitely missing a trick there! The burning flame at Yanar Dag is also awesome and not something I’ve seen before.

    1. It is such a magical world we love in isn’t it!? 😊 The volcanoes were great, but the museum was the worst.

  34. So crazy to get that close to the mud volcano edge😀

    We have a Petroglyphs museum here in Ontario too, but we are not allowed to take pictures, it is a sacred native place. I was shocked to see heavily armed police guarding those very few petroglyphs LOL

    Hope the weather is good!! xx

    1. The volcanoes are very bizarre and getting so close is even more bizarre. I don’t think I’ve ever seen so many petroglyphs in one area and most are in such great condition. And there were no armed guards 😊 although at musuems in Sheki (coming up) a staff member shadows you to make sure you don’t take pictures.


  35. This sounded like a once-in-a-lifetime and remarkable journey, Maggie.

    Everything, and I mean everything, about Gobustan, the mud volcanoes, the petroglyphs, and the eternal flames that you shared was like an otherworldly, magical, almost surreal experience (I feel). Wow! I loved the feature photo and the photo of the eternal flames.

    Truly enjoyed the share. Thank you so much for excellent insights into these places and the great research that you share to bring these places alive for the reader.

    Safe travels always to you both.

    1. It was once in a lifetime. What an amazing country. Not only a great capital, but so many fascinating geological and historical sites too! It is otherworldly. Thanks Suzette!

      1. You are most welcome Maggie. Cheers.

  36. Your curiosity about the world is exemplary.

    1. Thanks! The best compliment 😊

  37. Amazing! Never seen anything like those mud volcanoes before. They reminded me of the geysers in Yellowstone with obviously more sediment, but being cool to the touch, it is definitely something different. Was there as sulfur in the air as that has to be coming up from the depths bringing with it any gasses it passes through. Thanks for sharing these unusual sights with us!

    1. They are very cool. I’ve also seen thermal ones but never cool, bubbling mud. There is no sulfur smell either so they’re more pleasant that way too 😊 Maggie

  38. Amazing sights! We really enjoyed seeing all of these places too in December last year. Baku offers a fascinating mix of cultural and natural wonders.

    1. As soon as I saw the ‘musical instruments’ I remembered your post from the rock art site. It’s really incredible how many unique and historically important sites there are near Baku. Thanks for your comment Leighton, we must have been reading each other’s posts at the same time 😊

  39. I only read about mud volcanoes a few months ago – I never knew they existed. The video of how the mud ‘moves’ when stepped on the edge is very interesting. And the petroglyphs are just as amazing (it’s incredible how clear some of these rock paintings still are)!

    1. Both sites were so fascinating but I think the amount and quality of petroglyphs made that site the highlight for us

  40. Oh wow that is stunning.

    1. Thanks Melodie, it is really an exceptional place.

  41. […] You can read more about Zoroastrians in our posts A Guide To The Old City Of Baku and Gobustan’s Mud Volcanoes and Prehistoric Petroglyphs. […]

  42. Awesome place – mud volcanoes! You had me sold at sacrificial blood… How lucky you are to travel the road less travelled and brave enough to do it.

    1. 😂😂 I’m not sure I’m brave enough to live in those times though 😊

  43. Those mud volcanoes are nice surprises! I expect them to be boiling mud pools like in Japan, but no, they are cold and have cone shapes. Such a unique phenomenon! I have to laugh when I read your note about the museum. Why do they exhibit animal bones there? It doesn’t make any sense at all 🙂 If I’m not wrong, this cold mud can be used in cosmetics.

    1. I think the mud is used in mud baths and facials. I expected to see a lot of that in Baku, but didn’t notice it. Apparently, some people hop right in to bathe in these volcanoes too! Thanks Len

We'd love to hear from you, please leave a comment.
