Setting out to explore the jungle trails is one of the main activities during a stay in the Osa Peninsula. These are generally organised through your lodge and paid for locally, and you will be accompanied by a specialist guide to give you the best possible chance of finding more unusual species. Guides working here are some of the best in the country, drawn to this region by their own personal passion for wildlife, and their ability to spot rare birds, tiny poison-dart frogs or identify the best place for you to be to witness a troop of passing squirrel monkeys is quite remarkable.
