The Osa Peninsula is located on the Pacific coast of southwest Costa Rica and is home to one of the country's most incredible national parks: Corcovado.
My suggestion
When visiting the Osa Peninsula, you absolutely must go to Corcovado National Park, where there is a stunning array of fauna and flora to be seen.

The Osa peninsula is situated in the south west of Costa Rica, in the Puntarenas province. This part of Costa Rica is particularly wild and isolated.
My suggestion
I'd advise any diving fan to visit Cano Island (a local dive company can advise you). If you go out walking, don't go alone and, better still, find a local guide who can can show you the best trails.
