Costa Rica's South Pacific Coast is dominated by the Osa Peninsula. The Golfo Dulce separates this spit of land from the mainland; its divorced location has helped preserve the area's natural vegetation, creating forests so dense you'd be forgiven for thinking you were in the Amazon Basin instead.
One of the greatest attractions in Golfo Dulce is the wildlife these warm waters harbour, with whales and dolphins from both sides of the equator migrating here to raise their young along its sheltered shoreline.
This is a destination that attracts people looking to escape the crowds of the more popular northern coast and the links to the rest of the country are notoriously bad. However, for those looking for tranquillity, the effort to reach here is richly rewarded.
