The Puerto Morelos reef is part of the Mesoamerican Reef, the second-largest barrier reef system in the world, and it is only a few minutes’ drive from Casa Chanty. Coral grows unusually close to shore here, which makes it one of the easiest places in the Caribbean to snorkel a healthy reef without a long boat trip.

Why snorkel in Puerto Morelos?

• The reef is a protected national park, and its coral is among the best preserved on this coast.
• The barrier reef is only about 400 meters from shore, so boat rides are short.
• You can expect sergeant majors, parrotfish and barracuda, and sometimes rays and sea turtles.
• It is much quieter than the big tourist reefs farther south.

How snorkeling here works

Most visitors snorkel the barrier reef on a guided boat tour from Puerto Morelos. The boat takes about ten minutes to reach the reef, and the guide leads the group in the water. Tours run from a couple of hours to a half day, and some small-group options exist if you prefer a quieter experience.

• National park fee: a reef fee is charged per person, often paid in cash on site. Check whether it is included in the tour price.
• Life jackets: tours in the park require life jackets under federal regulations.
• Guide: the barrier reef requires a guided boat tour. Ask your operator about the rules for the shallow reef closer to the beach, which can differ.

Rules that protect the reef

• Never touch, stand on or kick the coral.
• Many tours do not allow any sunscreen in the water, so wear a UV shirt or rash guard instead.
• You may be asked to shower before entering the water.
• Don’t chase or feed sea life, and keep your distance from turtles.

What to bring

• A UV shirt, swimsuit, hat and towel
• Cash in pesos for the park fee, tips and snacks
• Your own mask and snorkel if you prefer a perfect fit, although tours include gear
• A change of clothes for afterward
