The dive
Isla Álamos has an unusual shape: its clear, shallow water runs as a ring under a low cave around a small island with álamo trees, which gives the cenote its name.
Profile and sections
Isla Álamos has an unusual shape: its clear, shallow water runs as a ring under a low cave around a small island with álamo trees, which gives the cenote its name. There is a nice stretch to dive, but it soon gets so tight everywhere that even in sidemount you can't see anything any more.
Practical: mostly a swimming cenote. At a cord across the access road you pay about 100 MXN entry.
- Depth and profile
- Shallow; depth unknown
- Configuration
- Soon tight everywhere, even in sidemount; backmount not worthwhile
Who can dive where
- At least Full cave
- Configurations: Sidemount / CCR / Small cylinders / no-mount (speleo sumps)
- Experienced divers only
This is how the planner decides who in your team may dive this cave. Rules your own trip adds (organizer, a mail, the AI) show with your trip.
How to get there
On the Tulum–Cobá road, with no sign on the main road; then about 2 km of dirt road with potholes to a black gate on the left. Park in front of the gate and walk the last stretch. No facilities.
