Snorkeling in Costa Rica starts over living coral reefs and leads deeper for the stunning sight of Manta Rays swimming by like a formation of underwater hang-gliders. The volcanic rock formations and rock pinnacles of the Costa Rican Pacific coast provide an ideal refuge for the marine life which inhabits these local waters. With an average water temperature of 24-28 °C (75-82 °F), you will be able to enjoy the true meaning of "tropical snorkeling".
A unique marine and terrestrial ecosystem is the National Park of Cahuita. Snorkeling is a fantastic way to explore the waters that are protected by the park. The live coral reef includes more than 240 habitats, 123 different species of fishes, 44 species of crustaceous, 140 shellfish and 128 various algae identified. You also observe 35 different coral species such as the fire coral, and the red and black coral. In the park you can observe many animals such as two or three toed sloths, white face monkeys, different types of crabs, morpho butterflies, birds and parrots.
Another interesting ecosystem is found at Golfo Dulce providing for an array of snorkeling opportunity for the beginning or advanced snorkeling enthusiast. Reefs are located within walking distance, and many other sites can be reached by kayak or motorboat. And an abundance of marine life can be observed within the gulf. Underwater visibility is affected by the amount of fresh water flowing into the gulf, thus best visibility occurs during the dry months. Snorkeling is perfect in the calm, clear waters where the waves break on rocks far from the shore.
Most snorkeling spots are located in secluded and rock protected beaches, and can be reached by bicycle, by car or even by horse.
