Catalinas Islands

This underwater paradise is located in the beautiful Guanacaste Province of Costa Rica. The archipelago of rocky islets, situated 9 miles off the coast, is a haven for marine life, making it one of the country’s top scuba diving spots.

This location is renowned for its diverse marine life. The Pacific Giant Mantas are a sight to behold, along with a myriad of other aquatic species such as white-tip reef sharks, moray eels, pufferfish, jacks, grunts, and many more. The islands are uninhabited, and their unique location, currents, and formation create the perfect environment for a rich concentration of marine life.

Water temperatures vary with the seasons, being cooler during the dry season (January and February) and warmer during the rainy seasons.

If you are visiting Tamarindo, Potrero, Flamingo, Brasilito, and other nearby towns, this is a destination you cannot miss.
