Local operators handle the boat run, site drop, and weather call for this wreck.
ARM Santos Wreck is San Carlos's first purpose-sunk artificial reef, a former Mexican Navy vessel off Punta El Cautín near Tetakawi. The wreck is a short boat run from Marina San Carlos and now draws scuba divers and guided snorkel visits over a shallow top and deeper main hull. Expect an easy charter approach, a compact wreck profile, and weather-sensitive planning on open water.

Depth range, seasonality, and planning context.
Reported Depth
6m - 17m
Depth Note
The top of the wreck is about 20 ft below the surface, and the hull rests at roughly 55 ft on sand.
Best Season
Late spring through early fall is usually the easiest window, with winter and spring also able to bring clear days.
Typical Conditions
Boat-access wreck with a shallow top, variable visibility, and surface chop that can increase after wind or storms.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
Treat this as a guided boat wreck: watch weather windows, stay alert on the surface, and plan conservative ascents because the wreck sits in open water.
Access Restrictions
Boat access only; plan with a local San Carlos operator and avoid rough-weather or harbor-traffic windows.
Legal Notes
This is a controlled artificial reef with state and navy involvement; follow local boating and dive rules around the wreck.
Community notes to help plan your visit.
Scuba Diving
Primary use case. Expect a shallow top, an upright main section, and a broken bow area that rewards repeat dives.
Freediving
Not a primary freedive site; only the shallowest structure suits advanced, supervised breath-hold visits.
Snorkeling
Guided snorkel viewing is possible on the shallow top, but scuba is the main way to explore the wreck.
