Tombant des Grottes - Saint-Gilles & West Coast
Tombant des Grottes is a solid choice when you’re diving out of Saint-Gilles, especially if you appreciate a good wall. Dropping to 26 metres, it’s an intermediate dive where you can really focus on the vertical reef structure. We often find schooling fusiliers hugging the wall, and the crevices here are worth a close look for morays and the occasional lobster. It’s a good site for photographers who enjoy macro and wide-angle on the same dive, with enough ambient light to make those colours pop.
