Frequently asked questions
No. Cenote snorkeling needs no certification or prior experience. You wear a mask, snorkel and life jacket and float on the surface. Guided snorkel routes through caverns like Dos Ojos require you to be a confident swimmer, but anyone comfortable in water can do an open cenote like Gran Cenote or Cenote Azul.
An Open Water diver certification is the minimum for guided cavern dives, which stay within the light zone near an exit. Full cave diving past the light requires a specialized Cave or Cavern certification and proper training. Never attempt to dive beyond your certification level in a cenote, it is the leading cause of accidents.
Neither is better, they suit different people. Snorkeling is cheaper, needs no certification and shows you the upper rock formations, fish and light through clear water. Diving costs more and requires certification but lets you enter the caverns to see stalactites, the halocline where fresh and salt water meet, and dramatic light beams from below.
