Colombia Shallows - Cozumel

Guerrilla Bay, for us, is one of those spots that just keeps giving, especially if you catch it right. We're talking about a cracking shore dive down on the NSW South Coast, and while 'The Pot' on the north side gets all the glory for experienced divers when conditions align, it's 'The Beach' that truly captured our attention. It’s got this interesting rocky reef, shelving up from the sand in these cool, angled walls that go from about 11m deep to maybe 3m or 4m, topped with thick seaweed. Sure, the visibility can be a bit hit or miss at 7m on average, but when it's good, it’s *really* good. You’re weaving through kelpy crevices, and we’ve routinely found blue groper here, big inquisitive ones, along with wrasse and luderick. Keep an eye out for octopus tucked into the rocks. We’ve even spotted Stingrays gliding over the sand flats. It's a surprisingly rich little ecosystem, proving you don't need huge depths for an engaging dive. Dive it on a calm day, definitely.
