The Osa Peninsula in the far south west of Costa Rica has never been the home of Tico’s. Most of the land has only ever been populated by Guaymi Indian’s, and for that reason the roads are poor and electricity is a luxury not enjoyed by many. National Geographic famously called it ‘the most biologically intense place on earth’. Which, when you think about it is quite a claim indeed. Certainly, this is Costa Rica’s most remote region, often cut off in the rainy season and only recently opened up to visitors. And that’s why not many people know about it. When I spoke to our two guides in Tortuguero National Park last week and inquired as to their favourite places in Costa Rica for nature, they revealed that whilst they love Tortuguero, Corcovado in Osa is right up there.
