You will fly over Puerto Jimenez and its stunning coastline to discover the town's beauty and undiscovered beaches; if you're lucky, you might be able to see marine life from our aircraft. The Corcovado National Park will thereafter be visible from the air. Despite being one of Costa Rica's most secluded areas, the park covers about half of the Osa Peninsula and extends over 163 square miles. According to National Geographic, the park is "the most biologically intensive location on Earth." The itinerary and locations of a tour can change depending on the weather.
