Scuba Diving in Costa Rica and Departing from Your Front Door

January 6, 2020

Costa Rica has 10 times more marine area than it does landmass, and is home to a large biodiversity of fish that dwell in its open oceans, inshore coastlines, and mangroves. From the North Pacifc Coast to the seas of the Osa Peninsula and across to the Caribbean, this wealth of aquatic life makes it possible to base an entire ecotour in Costa Rica around oceanic experiences.

Guanacaste in particular is home to some world-renowned dive sites, protected National Marine Parks, and a wide variety of animals like whales, dolphins, sea turtles, manta rays, white-tip reef sharks and bull sharks, as well as plentiful reef fish of many shapes and sizes.

In Las Catalinas, the natural world in the waters of Guanacaste is at your doorstep. The bay just off of Playa Danta provides the opportunity to depart from the beach in a kayak to tour four vibrant snorkel sites, or swim there yourself. Just down the coast are the mangroves of Las Baulas National Park, and the beaches of the Ostional Wildlife Reserve, which host the massive arribadas of thousands of Olive Ridley Sea Turtles.

Las Catalinas is also a central hub to dive sites like the Catalinas Islands, Dos Sombreros, Dirty Rock and many more.

Aside from a wide variety of reef fish, migratory open ocean fish, and large schools of smaller rays, the dive sites of Guanacaste are notable as a primary habitat for whitetip reef sharks. Ranging from around 1ft long as pups to up to 5ft long as adults, whitetips are found either solo or in groups that can range up to seven or more individuals, and use the waters around the Catalinas Islands as a place to rest and find food.

These waters are also ideal to encounter oceanic giant manta rays, the largest ray in the world at up to 23ft from wingtip to wingtip. Oceanic giant mantas are circumglobal and can be found throughout the world in tropical waters, but the waters from the Catalinas Islands to Bahía de Potrero are a common gathering point during manta migrations, and rays are especially prominent from the months of November to May.
