Corcovado has a well-developed trail system, though the trails are primitive. Several short trails (two to six hours) make for rewarding half- or full-day hikes. Longer trails grant an in-depth backpacking experience in the rainforest. Allow about three days to hike from one end of the park to the other. It can be hot and sweaty. Horseflies and mosquitoes can be a pain in the butt. From La Leona, it’s 21 km to Sirena, following the beach for most of the way. Allow up to eight hours. Beyond Salsipuedes Point, the trail cuts in land through the rainforest. Don’ttry this at high tide: you must cross some rocky points that are cut off by high tide.Consult a tide table before you arrives. The hike from La Leona to the Madrigal waterfalls particularly recommended, but few local guides will take you.
