Osa Peninsula
A trip here is about long forest hikes, close wildlife sightings and quiet nights away from the main tourist routes.
We may earn a commission. It never decides our picks.
The Osa Peninsula sits on Costa Rica's southwest Pacific coast, in Puntarenas Province. Most of it is lowland tropical rainforest, and Corcovado National Park covers much of the interior. The park is home to scarlet macaws, tapirs and several kinds of monkeys. Jaguars live there too, but they are rarely seen.
The peninsula suits travelers who want long hiking days, wildlife watching with a local guide and a slower pace. Getting there takes more effort than most Costa Rica routes, with small domestic flights, long drives on rough roads or boats, depending on your base. The dry season, roughly December to April, is the usual choice for hiking. From May to November, rain falls more often and trails can turn muddy. Plan at least two or three nights, and longer if you want more than one hike.

- Pack a dry bag for boat transfersSpray comes over the bow on the crossing to Drake Bay, and rain can start suddenly. Keep phones, documents and cash sealed in a dry bag.
