The Riviera Maya has many treasures but perhaps none so unique as its mystical cenotes. No trip to Puerto Aventuras would be complete without a visit to at least one of these remarkable locations. You can explore them on your own in an afternoon or combine your cenote visit with a tour of the archeological sites. Some cenotes are easy to find with parking and a range of amenities. Some are well-hidden and can only be reached after trekking through the dense Mayan jungle. No matter which you visit, each one is special and visiting a cenote (or two) should be on every Riviera Maya itinerary.
