Cozumel Three Reefs Snorkelling Boat Tour

Palancar Reef

Palancar Reef stretches for several kilometres off the southwest coast of Cozumel and is part of the Mesoamerican Reef, the largest reef system in the Western Hemisphere. Its shallow sections, often called the Palancar Gardens, are full of brain coral, sea fans and sponges, with parrotfish, angelfish, blue tangs and the occasional sea turtle or eagle ray gliding past.

On this tour Palancar is usually the first and deepest stop, and you spend around 35 to 45 minutes in the water. Because of the gentle current along the coast, snorkelling here is often a relaxed drift: the boat drops you upstream and picks the group up further along, so you float over the coral with little effort. Many visitors consider Palancar the reason a Cozumel snorkelling trip is worth it.

Columbia Reef

Columbia Reef lies south of Palancar and is known for its tall coral pinnacles rising from a sandy bottom, separated by channels and swim-throughs. The shallow parts, close to the beach, are ideal for snorkellers, with clear water, schools of yellowtail snapper and grunts, and a good chance of spotting stingrays resting on the sand.

Your guide picks the best section for the day's conditions and stays with the group, pointing out marine life as you go. The water in this part of the island is usually calm and visibility often exceeds twenty metres. Columbia is a little less busy than Palancar, which makes it a quieter, more relaxed second stop of around 35 to 40 minutes.

Playa El Cielo, the Starfish Shallows

El Cielo, which means heaven in Spanish, is a shallow sandbank off the southwest coast where the water is only waist- to chest-deep and an intense turquoise. It is famous for the large cushion sea stars that rest on the white sand, as well as small rays and fish, and it is one of the most photographed spots in Cozumel.

This last stop is the easiest of the day and perfect for children and less confident swimmers, who can stand on the sand while they look around. Please never lift the starfish out of the water, as even a short time in the air can harm them, and avoid kicking up the sand. Expect about 30 minutes here before the relaxed ride back along the coast.

Cozumel Reefs National Park

All three reefs lie within the Cozumel Reefs National Park, a protected marine area created to safeguard the coral along the island's southern and western coasts. A small marine park fee, paid in cash on the day, funds the rangers, mooring buoys and conservation work that keep these reefs among the healthiest in Mexico.

Rules are simple but important: no touching or standing on coral, no feeding fish and only reef-safe, biodegradable sunscreen or none at all. Life vests are compulsory for snorkellers in the park, and they are included in your gear. Following these rules is a big part of why the fish are so abundant and the water so clear when you visit.

Cozumel Island and How to Get There

Cozumel is Mexico's largest Caribbean island, about 18 kilometres off Playa del Carmen. Its main town, San Miguel, faces the mainland on the west coast, while the south of the island is lined with beaches, clubs and the boat docks used by reef tours. The departure point for this tour is on the southern coastal road at Km 6.5.

How to get to Cozumel: ferries cross from Playa del Carmen in about 40 minutes, and the island also has an international airport and a busy cruise port. From San Miguel the meeting point is a short taxi ride south. The best time to visit Cozumel for snorkelling is from April to August, when the sea is usually calmest; winter north winds can close the port on some days.
