After breakfast, visit a turtle nesting beach in the park to document any tracks from the previous night. Next experience the park's impressive coral reefs via a guided snorkel excursion by boat (snorkel equipment is not included; the option for scuba diving is available with an added charge). Experts consider that the seabed at María la Gorda is among the best for marine photography because of the water clarity and the abundant marine life such as shark, sting rays, barracuda, groupers, lobsters, eels, angel fish, crabs and more. Before dusk, head to the turtle beach where you will have opportunities to help the researchers measure the turtles, record data, and other tasks. Spend the night helping biologists with research or return to your room.
