Widely considered the most spectacular snorkeling spot in Costa Rica, Isla del Caño boasts a rich sea life in a tropical paradise. This small and lush island is home to scarlet macaws and toucans. Isla de Caño is bordered by a hard coral reef where sea turtles, sharks, rays and colorful fish abound at a shallow depth. Located off the coast of Corcovado National Park, it takes 1 to 2 hours by boat to reach the spot, but it is really worth the trip.

How to get to the Isla del Caño snorkeling spot

Isla del Caño is located off the Pacific coast of Costa Rica, west of Corcovado National Park.

The small island, which is a biological reserve, can only be visited during day trips with tour operators registered with the park. Tour prices range between $100 and $150 per person. Most of the tours include 2 snorkeling sessions around the island, lunch on the boat, and time to relax on a beach.

Isla del Caño tours depart mainly from 3 locations:

  • Uvita, at the gate of the Ballena National Marine Park. This is the main departure point, and is the most easily reached. It takes about 1.5 to 2 hours by boat to get to Isla del Caño from there.
  • Sierpe, a small village located inland, in a bend of the Sierpe River. From there, the boat trip to the island takes 2 hours. You travel 1 hour down the river and the mangrove and then 1 hour towards the ocean.
  • Drake Bay, in front of the island. It is the closest departure point to the island, but it is quite difficult to access. Because of this, there are fewer tours organized. From Drake Bay, the crossing to the island takes about 1 hour.

During the boat trip between the mainland and the island, you may have the chance to spot sea turtles, dolphins, or humpback whales (from June to September and December to April).

Isla del Caño snorkeling exploration tips

Your guide will most probably take you to the northern coast of the island, as it is more sheltered and several coral reefs have developed.

The reef forms plateaus and ridges that slope irregularly from the surface to deeper areas. The reef is composed of hard corals, mainly from Pocillopora and Porites genus. The coral is quite bleached, especially on the shallower parts of the reef, exposed to swell and tides.

Isla del Caño has a striking density of fish, one of the highest in the Eastern Pacific. Reef fish, such as the bluebarred parrotfish, the orangeside triggerfish, the king angelfish and the Mexican hogfish are common near the coral heads, including in shallow water. Dozens of other species can be seen, such as damselfish and butterflyfish.

Isla del Caño is also famous for its larger inhabitants. Whitetip reef sharks and hawksbill sea turtles are so common here that they are spotted by snorkelers almost every time. Occasionally, stingrays, eagle rays and barracudas are also seen.

Due to its offshore location, underwater visibility at this location is generally good, including during the rainy season. Because of the water clarity, snorkeling in Isla del Caño is possible almost all year round.
