North Pacific Coast Ostional

Prepare to hold your breath as you witness thousands of Ridley turtles come out of the sea and enter a deep trance while performing the spawning ritual. This massive arrival or turtles is called Arribada and it lasts 7 to 10 days in the rainy season. We assure you that you have never seen anything like this, as Ostional is considered the leading nesting site for the Ridley Turtle in the world.

Ostional is located in Nicoya Guanacaste, 70 kms south of Reserva Conchal. The best time of the year to visit is August to October for the nesting and November to January for the Hatching.

The Ostional National Wildlife Refuge was created in 1984 to protect this endangered species and other flora and fauna found in 790 acres of land and almost 20,000 acres of ocean.

The largest Arribada that has been recorded happened in 1995 counting 500,000 turtles, according to the National System of Conservation Areas.

Located north of the Tamarindo town, Playa Grande is part of Las Baulas National Marine Park. The largest marine turtle on earth, the Leatherback or Baula in Spanish, arrive to nest to the three main beaches of the Park: Ventanas, Langosta and Playa Grande. About 50% of the females of the Dermochelys Coriceaor Leatherback of the Eastern Pacific, spawn here.

The Leatherbacks nesting season starts in October until February, being December and January the peak months. The Hatchling season go from January to March.
