The Rio Claro rivermouth, deep in the Osa wilderness near Corcovado, has a long left off the river's sandbanks when a solid south-west swell lines up.

Getting there means hiking or taking a boat, and there's nothing there except jungle. You can camp, but bring everything with you. Because of that, it's almost always empty.

Go with a local guide, as crocodiles live in many river mouths in this area.

Getting there

Where to stay: This is remote, expensive, expedition territory, reach Drake Bay by boat from Sierpe or a rough drive. Book lodges well ahead and bring everything for the rivermouth spots (Sierpe, Rio Claro), which need boats, camping gear and self-sufficiency. Not a casual surf mission.

Transport, costs, where to stay and the rest of the waves in the area are in the Osa & the far south guide.
