Guide to Piedras Blancas: Costa Rica’s Breathtaking National Park

Piedras Blancas National Park is one of Costa Rica’s most biodiverse and least crowded protected areas. Located in the southern Pacific region near the town of Golfito, the park protects a vast stretch of lowland rainforest. Established in 1993, Piedras Blancas National Park covers more than 14,000 hectares of tropical rainforest.

It was created to safeguard habitats that were once heavily threatened by logging, hunting, and agricultural expansion. Today, the park serves as an important biological corridor linking the forests of the Osa Peninsula with inland protected areas. Here’s our comprehensive guide to Piedras Blancas National Park;

Overview of Piedras Blancas National Park

Situated along Costa Rica’s southern Pacific coast just outside Golfito, Piedras Blancas National Park encompasses over 34,595 acres of lush evergreen primary forest. These lush stretches of forest cover provide a crucial habitat for countless native plants and wildlife.

Established in 1993, the park’s creation marked a significant milestone for conservation, as much of the land had previously suffered from deforestation and hunting. Originally, the area was part of Corcovado National Park, known as the Esquinas Sector. However, by the mid-1990s, much of it had been privately owned and subjected to logging and other environmentally damaging activities.

Since then, charitable organizations have acquired large portions of this land and transferred them to public protection, ensuring the preservation of these vital ecosystems. Despite these efforts, some areas remain under private ownership. There are ongoing campaigns to raise awareness and secure additional funding so that the government can ultimately protect the park in its entirety.

Wildlife in Piedras Blancas National Park

Piedras Blancas boasts an extraordinary range of wildlife, supported by diverse habitats that include lowland forests, rivers, gullies, mangroves, lakes, lagoons, and even coral communities. These varied environments provide shelter and resources for an impressive array of mammals, birds, reptiles, and amphibians.

The park is notable for its populations of all four of Costa Rica’s monkey species: the squirrel monkey, white-faced capuchin, ornate spider monkey, and howler monkey. Big cats also inhabit the park, including ocelots, jaguarundis, pumas, and jaguars. However, these felines are extremely elusive and primarily active at night, making sightings rare.

Visitors are more likely to encounter toucans, scarlet macaws, kinkajous, coatis, two-toed sloths, anteaters, and over fifty species of bats. One remarkable natural event is the full moon spawning of needlefish. It occurs on the park’s steeply sloped beaches, where older sediments provide ideal conditions for their survival.

In addition, Piedras Blancas serves as a key gathering site for numerous bird species, making it a prime destination for birdwatching. Enthusiasts are often captivated by the vibrant colors and calls of toucans, macaws, and resplendent quetzals.

Best Time to Visit Piedras Blancas National Park

Piedras Blancas National Park is located in Costa Rica’s South Pacific region, one of the wettest areas in the country. The park experiences a dry season from November or December through April. The season is characterized by sunny days, relatively low rainfall, and consistent temperatures. Daytime highs range in the upper 80s to low 90s and nighttime lows in the upper 70s.

During this period, trails are more accessible, rivers are easier to navigate, snorkeling conditions are optimal due to clearer water. Visitors also have the best chances to witness bioluminescence in Golfo Dulce, particularly between January and April. However, the dry season coincides with the high tourist season, so expect larger crowds and higher prices.

The wet season, from May to November, transforms the park into a lush, green rainforest, creating dramatic waterfalls and a vivid natural landscape. During these months, there are fewer visitors, lower travel costs, and a deeply immersive experience for nature enthusiasts. However, heavy rains can make some trails muddy or temporarily inaccessible, and water levels in waterfalls may fluctuate later in the season.

Getting to Piedras Blancas National Park

Reaching Piedras Blancas National Park from San José involves several options depending on time, budget, and preference for convenience. For those traveling by car, the most flexible route is to take Route 27 to Caldera and then continue on either the Costanera Sur (Route 34) or the Interamericana Sur (Route 2) toward Paso Canoas. Look out for the turnoff at Kilometer 37, which leads to the Gamba-Guaycara area.

From this point, the park entrance is about a 30-minute drive along unpaved roads, so a 4×4 vehicle is recommended, especially during the rainy season. Alternatively, a taxi can transport you from the main road to the La Gamba Operations Center. Just leave the car in a safe public parking or at your hotel.

If you’re short on time, there are daily domestic flights from San José available to Golfito Airport or Puerto Jiménez Airport. Both options require additional ground transport, either by taxi or local bus, to reach the park. Puerto Jiménez Airport is a bit further compared to the one in Golfito.

For budget-conscious travelers, TRACOPA buses run from San José to Golfito, with a stop at Km 37 near the Gamba turnoff. From there, a short taxi ride or walk completes the journey to the park entrance, making the park accessible even without a private vehicle.
