Park Attractions
Corcovado National Park Costa Rica. Within the park is the drainage of Corcovado Basin, a broad sediment-filled oceanic embayment between Punta Llorona and Punta Río Claro (near Sirena), which extends inland from the Pacific Ocean 2-10 km eastward. The basin's low plain is dominated by creeks and meandering rivers, and is rimmed except to the west by uplands, which increase in altitude and irregular relief from an undulating plateau in the northwest part of the park (north of Llorona), to 2,444 feet in the southeast on the peninsula's highest cerros, Rincón and Mueller.

Rainforest at Corcovado National Park Costa Rica

The rugged uplands, produced by intensive tectonic activity and weathering (including frequent landslides), are dominated almost throughout by eroded narrow ridges and long steep slopes, with dense drainage networks.

Corcovado National Park Costa Rica. A virtually uninterrupted sandy beach extends for 20 km, with cliffs and pocket beaches at the northern and southern park headlands; there is a marine cave near the southern point. Up to ten tremors a day sometimes occur in the region, and crustal elevations have been observed.

Driving Directions

Travel to the south of the country on the Interamerican highway, 180 miles from San Jose, Costa Rica until Chacarita. The Rio Rincon crossroad is 20 miles past Chacarita. From this crossroad the west branch will take you to Drake (20 miles), and the south branch will take you to La Palma (3 miles) and then Puerto Jimenez (25 miles past La Palma).

It is also possible to reach San Pedrillo Station by taking a boat from the town of Sierpe, through Drake Bay to Corcovado National Park.
