Las Baulas National Marine Park – one of the largest nesting sites in the world for the vulnerable/endangered leatherback turtle – sweeps north of Tamarindo, encompassing the beaches of Playa Grande, Playa Ventanas, and Playa Carbón, plus hundreds of acres of mangrove forest.

For nature lovers, a Las Baulas turtle tour to watch these gentle giants lay their eggs is, undoubtedly, a must-visit during your Tamarindo vacation. (Note: Turtle nesting is a rare occasion so, before you book a tour, be sure to verify current conditions.)

The Incredible Leatherback Turtle

Leatherback turtles are the largest marine sea turtle in the world and the fourth-largest of all reptiles (second only to three crocodilians!). Sometimes called the "Earth's last dinosaur" – they've survived millions of years and outlived the last of the dinosaurs – this incredible reptile measures up to six feet long and weighs an impressive 1,500 pounds.

Another stand-out feature: leatherback turtles lack the traditional turtle shell, swapping a rock-hard carapace for a leather-like outer of oily flesh and skin. And that shell may be exactly what equips leatherbacks for another superlative: this massive sea turtle swims deeper than any other air-breathing animal on the planet – including whales, Emperor penguins, and seals. Diving as deep as 3,900 feet, leatherbacks swim in a cold, dark sea with a pressure equivalent to 120 of our above-the-sea atmosphere. A human would implode at that depth!

Impressive, indeed. Not to mention, magnificent. And in Costa Rica (and the world at large, really), our own Las Baulas Marine Park offers one of the best chances to spot leatherbacks in their natural environment.

When to Visit

You can visit Las Baulas National Marine Park any time of year. But, chances are, you're here for the leatherbacks. And that means you should shoot for nesting season: October through March – a lucky concurrence with much of our mid- and high-season, a popular time to visit. Hatchlings emerge a few months after nesting, with hatching months extending through April and sometimes early May.

Turtle Tours

During nesting season, turtle tours to Las Baulas are offered nightly. (Note: Tour availability sometimes depends on the turtles, local conditions, and other factors. Generally speaking, they're held every night.) Turtle tours are a wonderful and often moving experience. That said, they're also a waiting game: leatherbacks are large and lumbering on land, so you may wait a few hours until you see your first. (Books, board games, and other quiet wait-time diversions are encouraged on turtle tours.) Dark clothes are recommended, as they will not disturb the nesting mothers.

Note: If you're staying with us, Cris, our onsite (and free!) concierge will be happy to arrange a turtle nesting tour for you. As leatherback sightings can be very hit-or-miss at Las Baulas, we book our tours at nearby Ostional Wildlife Refuge, which witnesses huge olive ridley nesting events, plus leatherback and black turtle nesting.

Other Activities

Turtle tours may be the most famed activity at Las Baulas, but it's certainly not the only. The beaches of Playa Grande, Ventanas, and Carbón are beautiful and quiet – and the waves are killer!

Some of the best beginning-to-intermediate Tamarindo surfing can be had at Playa Grande, where surf offers a consistent mix of fast-breaking lefts and rights, with barrels, peaks and long rides. Swimming, sunning, and beach-walking area also lovely, especially at sunset.

How to Get to Las Baulas National Marine Park

From downtown Tamarindo, drive north and follow signs to Playa Grande. Alternatively, cross the Tamarindo-Playa Grande estuary by panga boat/ferry, and walk up the beach to meet your turtle tour.
