Snorkeling In Costa Rica: Mainland And Islands


With its impressive sandy beaches, rain forests and happy wildlife, Costa Rica is a “hot” holiday destination. However, when it comes to snorkeling, you need to do a little research in order to find (and access) the best locations. Well, we’re here to help you out.

Geography And Climate

Costa Rica is located in Central America between Nicaragua and Panama, with one side on the Pacific Ocean and one side on the Caribbean Sea. The Pacific side has no coral, and most of the landscape below water is mineral. The surf can be large, which attracts surfers and makes it difficult to snorkel there.

On the Caribbean coast you’ll find coral ecosystems along a 12-mile strip of land. Costa Rica has recorded 120 species of fish as well as 40 species of shellfish. You may see eagle rays and nurse sharks too. 

Costa Rica has a tropical climate, but it has humid forest areas and mountains where it rains all the time. This rain falls to the ground and flows towards both of its coastlines. The water picks up dirt which makes it very cloudy.

Our Top Snorkel Spots

Cahuita National Park

One of the best spots on the mainland is the Cahuita National Park. You will find 120 species of fish, 35 different kinds of coral, 40 crustacean species, and 120 types of mollusk. You will be able to walk straight into the beautiful turquoise water from the beach. The park is protected, so you need to hire a guide that takes you snorkeling. The video below should give you a great impression of the park.

Gandoca-Manzanillo National Wildlife Refuge

Another spot on the mainland is the Gandoca-Manzanillo National Wildlife Refuge off the Caribbean coast. This spot has protected bays with shallow coral reefs. You will find colorful fish and sea turtles, dolphins and even manatees. 

Papagayo Peninsula

The Papagayo Peninsula is located in the northwest province of Guanacaste. There are a number of protected inlets and bays that are calm and good for snorkeling. You can go to Playa Huevo, Playa Penca, Playa Jicaro, Playa Blanca, Playa Buena, Playa Junquillal and Playa Nacascolo.

Best Snorkeling Is Found On The Islands

Cano Island

You will find the best snorkeling to be a boat ride away near some of the islands. The Cano Island Biological Reverse is on Cano Island, about 13 miles offshore from the Osa Peninsula at Drake Bay. It has incredibly beautiful blue waters, and there is very good visibility underwater.

You will see a variety of marine life, including sea turtles, white-tipped sharks, stingrays, manta rays, moray eels, barracuda, tuna, snapper, dolphins and possibly a humpback or pilot whale.

There’s a video a little further down below. It should give you a better impression of this location.

Final Thoughts

Even though snorkeling from the mainland is possible, the better snorkel spots are found near the islands. This obviously requires you to join a boat tour, but hey, the guides are nice and provide a lot of helpful information.

The “dry season” lasts from around January until April. That’s when precipitation reaches some of it’s lows and temperatures are between 70 and 86°F. Still, temperatures stay very comfortable all year round.

Last but not least, sunny days will allow for some awesome photography! Feel free to read our guide about snorkeling with a GoPro.
