This day you should bring your beach towel and snorkeling gear along (available for rent) . It all stars with an early departure. This is an hour boat trip each way. In the early morning, we land on the island. Immediately upon arrival the guide leads a hike up to the site of the Indian graves that are found all over the central plateau, where archaeologists unearthed mysterious stone spheres and finely worked artifacts, testimonies to a vanished culture. Along the way, notable differences between the island and mainland forest will be pointed out.

Following lunch time, you are at your leisure to swim and soak up the sun, you will be free to visit other parts of the island or snorkel among the corals and brightly colored reef fishes. Snorkelers will delight in the schools of brightly colored fish.

By late afternoon, it's time to return to mainland, a short distance by boat, but an entirely different world. Watch out for the dolphins along the way! Overnight stay is not permitted on this Biological Reserve except by express permission of the Costa Rican National Park Service for visits involving active research.
