Costa Rica: A Whale Tail in Ballena National Marine Park

There’s a unique feature on Costa Rica’s southern coast that only exposes itself during low tide. A long sandbar joins to a rocky point over a kilometer away to make the form of a whale’s tail.

Ballena National Marine Park

Southern Costa Rica’s Ballena National Marine Park (Parque Nacional Marino Ballena) is a wonderful spot along the Pacific coast. Most of the park is in the ocean, but on the edge is a 3 ½ km long beach that includes the beaches Uvita and Colonia. We walked most of the length of the beach and saw a flock of red macaws, a coracora and skittish shorebirds running at the water’s edge. The sand on the beach is not the nicest since its quite muddy, but the scenery is spectacular with the palm trees lining the edge. You can only access these beaches after paying at the park entrance gates so they are relatively quiet.

The area was designated as a national park to protect Humpback Whales that migrate to this area from the north and south at different times of year. We didn’t go whale watching, but there’s another whale feature in the park that we wanted to see. A naturally occurring whale’s tail image is formed by ocean currents and becomes exposed during low tide.

Uvita Point is a formation of rocks over 1 km offshore from Uvita Beach. During high tide, you can barely see the tips of these rocks. As the tide begins to recede, ocean waves come around the sides of Uvita Point and crash into each other from both sides. These waves and their currents have formed a fascinating sandbar. As the tide recedes more, the waves form interesting geometric patterns from their opposing forces. It was so much fun walking out to Uvita Point as the tide was going out and a sandbar was emerging with every step. Waves were coming in at us from both side of the sandbar and meeting in the middle forming interesting zig-zag patterns. When the tide is at its lowest, a completely exposed spit joins the mainland to Uvita Point’s rocky island over 1 km away.

The pictures below show a chronology of the receding tide and the appearance of a sand bar. You can’t see the whale tail image from the beach so we’ve included an aerial picture from the web. During high tide, the aerial shot would look like a normal beach.

We have since read that the 2011 tsunami that hit Japan also caused damage to the whale tail spit. The power of Mother Nature however, meant that just one month later it was back to near normal.

Finca 6 Archeological Museum

Fifty kilometers south of Uvita is one of a only a few archaeological museums in Costa Rica. There are mysterious large stone orbs spread across south western Costa Rica. Archaeologists don’t know much about these giant stone spheres or the people who created them. The stones were crafted into spheres between 200 BC to 1500 AD. It’s believed they were for astronomical or religious purposes or to demonstrate the wealth and power of the chief. They range in size from a few cm to almost 2 m in diameter. Researchers believe they know the tools and methods that were used to make them, but the rest is still a mystery.

The spheres were only discovered in the 1930s when the area was being cultivated for banana plantations. Many of them were damaged by bulldozers and machinery. One farming area, Finca 6, had a high proportion of the spheres and a few that were undisturbed. Finca translates to farm in English, and Finca 6 Archeological Museum, is located in what used to be a banana plantation.

We were curious to see these strange stone artifacts, but unfortunately the museum was a huge disappointment. There were only 2 dozen or so spheres on the museum grounds. Some are partially buried, others are above ground. We expected more from the museum and in fact on the drive back we saw at least a dozen scattered throughout a small park and on people’s lawns in the town of Palmar Sur. If you really want to see these artifacts we suggest walking through Palmar Sur for free rather than spending $12 USD to visit the disappointing museum.


Visiting Marino Ballena National Park

Entrance Fee – $7 USD each and you can go in and out multiple times per day. When we were there it was free after 4pm.

Note: Remember to check the times for low tide.

Getting to Marino Ballena National Park

By car – The closest town to the park is Uvita which is located on the Costanera Sur Highway. There is a parking lot at the Uvita Beach entrance.
By bus – Public buses run up and down the Costanera Sur highway allowing you to get to or from any of the neighboring cities. They only run a few times a day though and are not usually air-conditioned. Tracopa has air-conditioned buses that travel through Uvita on their way to or from San Jose. They may charge you the full fare though, no matter where you get on or off.
By Air – The closest airport is in Quepos, 67 km north.

www.centrocoasting.com is a great resource for bus schedules in Costa Rica.

Where to stay

The closest town is Uvita. There are quite a few hotels and restaurants near the Costanera Sur highway. From there you can walk 30 minutes, or take a taxi to the park entrance. There are also backpacker hostels near the park entrance. We stayed in Uvita and loved seeing local homes surrounded by lush, tropical gardens.


Getting to Finca 6 Museum

By car – The Museum is located between small towns of Palmar Norte and Sierpe just off Hwy 223. If you have a car you could easily visit on a day trip from Uvita.
By public bus – Get off at Palmar Norte located on the Costanera Sur Highway. Finca 6 is 10 km south along Hwy 223. There are a few pubic buses traveling from Palmar Norte toward Sierpe, but you will have a couple of hours to wait for the return bus back to Palmar Norte.
