Boat-access wall dive with coral canyons off Mahahual.
Boat-access wall dive with coral canyons off Mahahual.
This site is normally dived from a local boat leaving Mahahual, and the captain or instructor chooses the exact route based on conditions.
40 Cañones is a short-boat wall dive off Mahahual where coral ridges break into narrow canyons, cuts, and sheltered pockets along the reef edge. Divers typically follow the reef top before dropping onto the outer face, using the canyon lines to add contour and protection without turning the dive into a full drift.
Safety Notes
Keep buoyancy tight around the coral cuts, follow the guide's chosen line for the day's visibility and current, and stay within the planned profile for the wall route.
Access Restrictions
Access is by dive boat from Mahahual rather than independent shore entry. Operators may swap the site on the day if visibility, current, or surface conditions are not suitable.
Legal Notes
Mahahual diving operates inside a protected reef system on the Mexican Caribbean coast. Expect standard marine-park rules from your operator and the local environmental fee commonly charged for reef dives in the area.
Community notes to help plan your visit.
Scuba Diving
Best suited to scuba divers who want a structured wall dive with canyon features, a straightforward boat drop, and enough profile options to stay shallower or extend a little deeper along the outer face.
