Drake Bay is positioned in one of most biologically diverse ocean ecosystems in the world. The area is known as the Costa Rican Thermal Convection Dome. The ocean water has a warm top layer with a cold low-oxygen layer below. The combination creates a healthy marine habitat for a variety of creatures. Whales, dolphins, tuna, marlin, manta rays, sea turtles, and more live in these waters and benefit from this year round thermal dome. We are fortunate to host two migrations of humpback whales and see large pods of dolphins. Year round the bottlenose, roughtooth, and spotted dolphins are observed. This area of Costa Rica water should be considered a marine sanctuary. Our in-house naturalist guides has been certified by the marine protection foundations, Keto, MarVida, ProMar, and by the Costa Rican Park Service to take visitors to observe cetaceans in their nature habitat. This tour requires a minimum of four people.
