Caño Island sits about 20 kilometers off the coast of Drake Bay, surrounded by some of the clearest water in Costa Rica. Part of the Isla del Caño Biological Reserve, this small uninhabited island is home to thriving coral reefs, massive schools of tropical fish, and some of the most exciting underwater encounters you can have on the Pacific coast.
If you are planning a trip to Drake Bay and want to explore this underwater paradise, you have two options: snorkeling or scuba diving. Both are incredible. But which one is right for you? In this guide, we break down exactly what each experience is like so you can choose the perfect tour.
Why Caño Island Is One of the Best Spots in Costa Rica for Marine Adventures
Caño Island consistently ranks among the top snorkeling and diving destinations in all of Central America. The waters around the island offer visibility of 20 to 30 meters on a good day, which is exceptional for the Pacific coast. The island is protected as a biological reserve, meaning marine life here thrives in ways you simply won’t find at more crowded destinations.
From Drake Bay, the boat ride to Caño Island takes around 40 to 50 minutes, and the journey itself is part of the adventure. It is common to spot dolphins riding the bow wave, and during whale season (July through October and December through March) you may see humpback whales breaching in the open water before you even reach the island.
What Is the Caño Island Snorkeling Tour Like?
The snorkeling tour at Caño Island is designed for everyone. You don’t need any previous experience. Your guide will provide all the gear and give you a briefing before you enter the water, so even first timers feel comfortable from the start.
You will snorkel over shallow coral gardens close to shore, where the reef drops off gradually and the water is calm and warm. The visibility is almost always excellent, giving you a clear view of the colorful world below.
Marine Life You Can Expect While Snorkeling
Snorkeling at Caño Island is full of surprises. You can expect to see large schools of tropical fish, including parrotfish, angelfish, and surgeonfish. Sea turtles are regular visitors, and it is not unusual to spot a hawksbill turtle gliding past you just a few meters away. White tip reef sharks often rest on the sandy bottom near the reef edges, and if you are lucky, you may encounter an eagle ray cruising through the blue.
Starfish, sea urchins, moray eels, and octopuses add to the experience. Your guide knows where to look and will point out creatures you might otherwise swim right past.
Who Is Snorkeling Best For?
Snorkeling at Caño Island is perfect for families with children, couples looking for a relaxed marine experience, and anyone who loves the ocean but does not have a scuba certification. It is also a great choice if you prefer to stay near the surface and enjoy the scenery at your own pace.
What Is the Caño Island Diving Tour Like?
The diving tour takes you deeper into the underwater world of Caño Island, reaching depths of 15 to 25 meters depending on the dive site. You will explore underwater rock formations, swim through schools of fish so thick they block out the light, and have close encounters with larger marine species.
The dive sites around Caño Island include dramatic walls, coral covered boulders, and sandy channels where sharks and rays patrol. Your dive guide will lead you through the best spots based on current conditions, ensuring you get the most out of every minute underwater.
Marine Life You Can Expect While Diving
Diving at Caño Island opens up a whole new level of marine encounters. In addition to everything snorkelers see, divers regularly encounter large schools of bigeye jacks that swirl in mesmerizing formations. White tip reef sharks are almost guaranteed, and bull sharks make appearances at certain times of the year.
Giant manta rays, whale sharks (rare but documented), and even hammerhead sharks have been spotted at deeper dive sites. The coral formations at depth are home to nudibranchs, lobsters, and moray eels of impressive size. For underwater photographers, Caño Island is a dream.
Who Is Diving Best For?
Diving at Caño Island is ideal for certified divers who want a world class Pacific dive experience. Whether you are an intermediate or advanced diver, the sites here offer plenty of variety. If you hold an Open Water certification or higher, this tour is for you.

Best Time of Year to Visit Caño Island
Caño Island can be visited year round, but conditions vary by season.
The dry season from December to April brings the calmest seas and the best visibility, often exceeding 25 meters. This is the most popular time for both snorkeling and diving.
The green season from May to November can bring choppier seas, but visibility is still good on most days and the marine life is just as abundant. Whale season overlaps with the green season, so you get the bonus of humpback whale sightings on your boat ride.
Water temperature stays warm throughout the year, typically between 26°C and 29°C, so a thin wetsuit or rashguard is all you need.
