Getting There:
There are a number of access points for Corcovado, but Puerto Jiménez is generally considered the gateway to the area.  If you don’t have a 4WD vehicle transportation to the park boundary is available by private or collectivo taxi from there.  If you’ve got a reservation with a lodge they’ll be happy to help you with travel arrangements and suggested routes.

Driving
Take the Pan American Highway East out of San José, the road curves South and changes designation from Highway 1 to Highway 2, although it's still the Pan American Highway. About 30 miles (50 km) past Cartago you climb over Cerro de la Muerte, and you will reach San Isidro el General after a total of 92 miles (153 km) (approx. 3 1/2 hours). Continue south on the Pan American Highway to Chacarita/Piedras Blancas to where you turn right (southwest) on 245 towards Puerto Jiménez.

Three access routes for the park branch off of the road to Puerto Jiménez. The first is the turnoff (right) for Drake Bay (4WD, sometimes impassable) at Rincón 44 km from the Pan American Highway.  The right turn for the track (4WD, sometimes impassable) towards the Los Patos station is 9 km further along at La Palma and towards Dos Brazos and the Tigre station 18 km past that. 

Total distance from San José to Puerto Jiménez is 240 miles (395 km, approx. 9 hours driving time). The final road access to Corcovado is past Puerto Jiménez to the south and 43 km around Cabo Matapalo to Carate (4WD recommended).
