Elephant Ear Canyon
Depth is the range from the top of the site to its usual maximum; "recommended cert" is the mainstream-agency level operators usually ask for, not a legal rule. Currents and visibility change daily — treat everything here as planning ranges.
A river of white sand pours through a cut in West Caicos's wall, and partway down the canyon grows the site's namesake: an orange elephant ear sponge broad enough to shade a diver, one of the largest most visitors will ever see. The wall on either side is classic West Caicos, deeply fissured and hung with rope sponges, while the sand channel below traffics stingrays and the odd passing reef shark. Photographers budget half their dive for the sponge alone, framing buddies against it, then ride the canyon rim back to the shallows where garden eels colonize the flats.
The moment you come for: Giant elephant ear sponge, sand-river canyon through the wall
Topography: Sand canyon cutting through a vertical wall
Entry: Reached by fast boat or liveaboard from Providenciales along West Caicos's protected west wall.
Know before you splash
Hazards: Depth accumulates quickly in the canyon; the sponge sits below twenty meters, so plan the profile around it.
Nitrox: Worth it here — profiles sit in the range where enriched air meaningfully extends no-stop time (with the training to use it).
