Crystal cavern light beams in the jungle.
The dive
Crystalline freshwater caverns lit by cathedral beams of sunlight, with surreal haloclines where fresh and salt water blur. Cavern lines keep daylight in view; cave diving is cave-certified only.
When to go
Diveable all year in stable 24–25 °C freshwater; light beams are at their most dramatic in the midday sun.

Logistics
| Getting there | International flight + short inland drives. Fly to Cancún (CUN), drive to the Riviera Maya (Tulum/Playa del Carmen); cenotes are short drives inland. |
|---|---|
| Where to stay | Resort-town base (day trips). Tulum or Playa del Carmen base; cenote diving is guided day trips into the jungle. |
| Operator to look for | Cavern guides only for open-water divers — full cave is a separate technical qualification. |
