Cenote Azul is a circular, open-air sinkhole a few minutes south of Bacalar town, just off Highway 307. The water is more than 90 metres deep and is not connected to the lagoon, which is why it looks so different: a ring of bright turquoise around the edge gives way to deep blue and then almost black in the centre. A safety rope runs across the cenote, and life jackets are required for weaker swimmers. The site has changing rooms, restrooms and a restaurant with a view of the water, and entry is paid in cash at the gate. The tourism board describes it as an open-air cenote with deep water, located just outside the lagoon, and it is the best known of the lagoon cenotes. It is also the busiest, so the time of day makes a large difference to the experience.
Why go
Swimming in water that drops into darkness beneath you is a memorable experience, even if you stay close to the edge. The setting is lush, with trees leaning over the shoreline, and the restaurant terrace is a pleasant place to rest with a drink after your swim. A short walk from several lagoon-front hotels makes it easy to combine with a morning out and a long lunch.
Rules and etiquette
Sunscreen, lotions and insect repellent are not permitted in the water, because they harm the delicate ecosystem. Shower or rinse before you swim if the site offers it, and wear a rash guard if you burn easily. There are no lockers, so bring minimal valuables and cash. Entry is a modest cash fee, and the restaurant accepts cards, though it is wise to confirm the payment options on arrival. Life jackets are provided and recommended for anyone who is not a confident swimmer.
Timing
Weekends and holidays can be crowded, as the site is popular with tour groups and families. Go early on a weekday for the quietest water and the best light on the surface, or late in the afternoon when the day-trip crowds have left. Pair Cenote Azul with Cenote Cocalitos for a contrast, since Cocalitos is shallower and known for its stromatolites. If you are visiting in the rainy season, check conditions on the day, as visibility and access can change.
