Boulder City is one of our favourite spots for a seriously slow dive. Drop down, and you’re into a world of big, star-shaped boulders scattered across a gentle slope. It’s not about grand vistas here; it’s all about the tiny stuff, the kind of creatures you have to really look for. We’ve spent whole dives just combing the sandy patches and the edges of the rocks, finding everything from frogfish in mottled camouflage to delicate seahorses, both the lined and the tiny dwarf varieties. The Grenada dive community considers this a proper muck dive, and they’re not wrong. Visibility tends to sit around the 12-meter mark, which is plenty for peering into crevices and sifting through the mud for a glimpse of a sand stargazer or a shy hamlet. If you’re a macro enthusiast, someone who loves to spend twenty minutes with a single creature, this is your happy place. Forget racing around; Boulder City rewards patience and a keen eye. We’d suggest going early in the morning, before other boats stir up the sediment, to maximise your critter-spotting potential.
