No matter what adventure you crave, you’ll find it in Costa Rica — both topside and underwater. Try speeding through the rainforest canopy on a zip line or scuba diving with bull sharks. Bordered by the Pacific Ocean and the Caribbean Sea in the heart of Central America, Costa Rica is a prime ecotourism destination and boasts some of the world’s most biologically diverse habitats – including rainforest, volcano and mangrove ecosystems. While the Caribbean coast has yet to develop a serious scuba diving infrastructure, diving off the Pacific Coast is nothing short of spectacular. The underwater volcanic rock formations and pinnacles are home to small hard corals, sponges and gorgonians. Guanacaste is a giant bay off the northwest coast that provides access to Catalina and Bat Islands – key dive areas. The southern area is a protected biological reserve and offers the chance to see rays, turtles, and white-tip reef sharks. Plus, you’ll see large schools of fish swimming overhead on almost every dive. You can also get out to Cocos Island off the Pacific coast to dive with its hammerhead shark schools, whale sharks and manta rays.
- Cocos Island – Because reaching Cocos Island National Marine Park requires a lengthy boat trip, most divers visit on a liveaboard dive vessel. Besides the pelagic species – marlin, sailfish, rays and sharks – that are drawn to the area, you’ll find more than 25 endemic fish species, including the red-lipped batfish. Whales also use the Cocos Island seamount as a place to congregate and calve.
- Caño Island – Expect to find a large number of reef fish species on the pinnacles and coral reef that surround the island. You’ll also likely see bigger creatures such as manta rays, free-swimming moray eels and sharks. Mammals, such as orcas, dolphins, humpback and pilot whales are known to cruise through.
- Catalina Islands – The unique underwater structure is what draws divers to these islands. Look for arches and caves, plus vibrant coral growing on the volcanic rock formations. You may see several different kinds of rays and sharks as well as sea turtles.
- Big Scare, Bat Island – What better way to get your heart racing then by diving with bull sharks? You’ll also have the chance to spot other large pelagics like manta rays, sailfish and the occasional whale or dolphin. This dive site drops to more than 30 metres/100 feet and can have a strong current. It is best suited for advanced divers.
- Virador – This volcanic island acts like a magnet to sea life. There’s a shark cave at 10 metres/33 feet and frequently there are large stingrays and white-tipped reef sharks at 22 metres/70 feet. You’ll also see huge schools of grunts, snapper, king angelfish and sergeant majors.
- Tortuga Islands – There are three shipwrecks to visit off the Tortuga Islands. The Franklin Chang Diaz and Coronel Alfonso Monge were both Coast Guard ships that now lie comfortably below the surface within scuba diving depths. Nearby, the Caroline Star, sits a little deeper at 30 metres/100 feet and is home to white-tip reef sharks and a variety of tropical fish.
