Explore the mysteries of an underwater world on a snorkeling day in crystal-blue Caribbean waters. Cruising about one hour north of our launch site from the Puerto Aventuras Marina brings us to the calm, tropical waters of the sheltered INAH Reef. For the opportunity of a lifetime, you can enjoy an underwater adventure, observing tropical, colorful reef fish and, if you are lucky enough, even get to swim with the giant sea turtles that have returned to this same spot for generations. Heading to an area protected by rocks with its calm, chest-deep water, you can continue to swim and relax with the view.
