> My third and fourth dives after getting my open water certification were in cenotes around Playa Del Carmen and that experience was just mind blowing.
Overhead diving, especially in caves, is extremely dangerous without extensive training. Too many operators down there will take new divers on very questionable “cavern” tours with sections of no natural light / visible exits, single primary lights, and single tanks.
Do your due diligence and remember nothing in the cave is worth dying for.
