More ways to explore the area's outdoor wonders
You step off the skiff onto a narrow beach and the rainforest takes the lead — vines tugging at the morning humidity, toucans scolding from high limbs, and the surf at Golfo Dulce marking where sea gives way to primary jungle. The walk to Sirena Ranger Station is short—about 2 km—but each bend can rearrange the day: a troop of howler monkeys, a flash of hummingbird, or the distant bruise of a tapir moving through understory.

Wildlife
History
Corcovado was established as a national park in 1975 to protect one of Costa Rica’s last extensive lowland rainforests; Sirena has long been a focal ranger outpost for research and protection.
Conservation
Visitor numbers and strict park rules help limit impact; traveling with licensed guides supports park fees, local rangers, and anti-poaching efforts.
