Costa Rica is world-famous for its wildlife, but many visitors are surprised to discover that some of the country’s most incredible animals live beneath the surface of the ocean.

Whether you are joining a guided snorkeling trip or exploring from a kayak, every snorkeling adventure in Costa Rica is unique.
Join our Guided Kayak and Snorkel tour and discover the incredible marine life in Guanacaste.
Why Snorkeling in Costa Rica Is So Special
Costa Rica’s Pacific coastline is shaped by volcanic rock formations, rocky reefs, tropical bays, and nutrient-rich ocean currents that attract an incredible variety of marine species.
Unlike coral reef destinations in the Caribbean, snorkeling in Guanacaste is centered around volcanic reefs and rocky ecosystems that provide shelter for fish, rays, eels, and sea turtles.
The Gulf of Papagayo is one of the best places in Costa Rica for snorkeling because of its protected bays, calm conditions, and rich marine biodiversity.
Warm water temperatures between 26–28°C most of the year make snorkeling comfortable. Between April and November the ocean is the calmest and offers generally better visibility. But conditions in the Pacific can change from day to day so contact us directly for your next snorkeling trip.
Sea Turtles
One of the most exciting animals you may encounter while snorkeling in Costa Rica is the sea turtle.
Sea turtles are commonly spotted in the Gulf of Papagayo, especially around rocky reefs and shallow bays where they come to feed and rest. Watching a turtle glide effortlessly through the water is an unforgettable experience for many visitors.
Green sea turtles, Hawksbill turtles, logger head and olive ridley turtles are among the species most commonly seen in Guanacaste.
While sightings can never be guaranteed, turtles are regularly encountered during snorkeling and kayak tours in Playas del Coco.
Tropical Fish
Costa Rica’s volcanic reefs are home to a colorful variety of tropical fish species.
As you snorkel along rocky formations, you may encounter:
Angelfish
Pufferfish
Jacks
Parrotfish
Sergeant majors
Butterflyfish
Triggerfish
and over 100 species more !
The abundance of marine life around the reefs makes every snorkeling session different and exciting.
Shallow reef areas around Playa Penca and the Pelonas Islands are especially active with marine life and offer excellent visibility during calm conditions.
Rays
Rays are another highlight of snorkeling in Costa Rica. Southern stingrays and spotted eagle rays are occasionally seen gliding gracefully over sandy areas and rocky reefs in the Gulf of Papagayo.
Mobula rays are also famous in Guanacaste waters and can sometimes be seen traveling in large schools during certain times of the year.
Seeing rays move effortlessly through the water is one of the most memorable moments many guests experience while snorkeling or kayaking along the coastline.
Octopus & Moray Eels
The volcanic reef systems around Playas del Coco create perfect hiding places for octopus and a large variety of colorful moray eels. Want to know more about fish fish species and other marine life in Costa Rica ? Take our Fish Identification quiz.
Octopus are masters of camouflage and often hide among rocks and crevices during the day. Spotting one requires patience and a careful eye, but it is always a special encounter.
Moray eels can also sometimes be seen peeking out from rocky holes while snorkeling around reef formations.
These unique creatures add an exciting sense of discovery to every snorkeling or scuba diving adventure.
Reef Sharks
Small reef sharks are occasionally encountered in the Gulf of Papagayo, especially around rocky reef systems and islands.
These sharks are shy, non-aggressive animals that play an important role in maintaining healthy marine ecosystems.
Seeing a reef shark while snorkeling is a thrilling experience and often becomes one of the highlights of the tour for adventurous guests.

Dolphins & Humpback Whales
During certain seasons, Costa Rica’s Pacific coast becomes even more spectacular.
Humpback whales migrate through the waters of Guanacaste every year, and dolphin sightings are also possible along the coastline.
While whales are usually spotted from the kayak rather than while snorkeling, seeing a whale breach in the distance during an ocean adventure is an unforgettable experience.
The Gulf of Papagayo is one of the few places where visitors may experience snorkeling, kayaking, and whale watching all in the same morning.
