The Osa Peninsula & Corcovado







Osa Peninsula

Curving out from the south Pacific coast  like a crab claw, the Osa Peninsula is the site of Costa Rica’s most prized national park: Parque Nacional Corcovado. Named “the most biologically-intense place on earth” by National Geographic, over half of all species living in Costa Rica can be found here.

Residents include:

  • Harpy Eagles
  • Baird’s Tapirs
  • Jaguars
  • Two-toed and Three-toed Sloths
  • Scarlet Macaws
  • All four Costa Rican monkey species

Corcovado’s 105,000 acres contain at least eight biomes, including the largest primary forest in the American Pacific and one of the world’s last remaining lowland tropical rainforests. Registered visitors can hike either an inland trail or a coastal track. These routes are best seen with the aid of a naturalist guide.

San Pedro Claver
Twelve miles off the peninsula’s western shore is Isla del Caño Biological Reserve, a sacred site for the indigenous Diquis people. The island is surrounded by coral reefs, home to an abundance of colorful fish and lobsters. The island can be visited by yacht charter for snorkeling or diving.

Osa is a rainforest region; rain is to be expected.

The best time to visit is between January and April, when rains are less frequent, and roads are in better condition.

What is the Weather Like?

Costa Rica is located in the tropics and close to the equator and is considered a rainforest country with warm temperatures being characteristic throughout the year. There are two well-defined seasons:

Dry Season: December – April
Green Season: May – November

Osa is a rainforest region; rain is to be expected year-round. The rain, especially on the Pacific coast, typically occurs during the afternoon or evening and is “warm”. You’ll experience a short mid-year mini Dry Season towards the end of July and the beginning of August when rainfall decreases significantly for 3-4 weeks. The rainiest months are September and October, especially in the South Pacific region. The best time to visit is between January and April, when rains are less frequent, and roads are in better condition. From July to November, many of parts of Corcovado are closed on account of flooding.

Over the course of the year, the temperature typically varies from 75°F to 85°F.

These averages are changing, please check extended weather forecasts using your favorite weather app prior to departure.
