Elephant Ear Canyon

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.

您此行的高光时刻: Giant elephant ear sponge, sand-river canyon through the wall

地形地貌: Sand canyon cutting through a vertical wall

入水方式: Reached by fast boat or liveaboard from Providenciales along West Caicos's protected west wall.

危险因素: Depth accumulates quickly in the canyon; the sponge sits below twenty meters, so plan the profile around it.
