    Snapper Hole, on Grand Cayman's East End, is a chaotic good kind of dive. It’s a tangle of swim-throughs and caverns that always keeps us guessing, maxing out at about 20m. We love getting lost in its maze-like structure, ducking under arches and squeezing through tight spots, though if you're not comfortable with overhead environments, maybe ease into this one. The BBC documentary cavern is impressive, dark and full of nooks. Look for the massive 1872 Spanish anchor propped against a coral head, a real piece of history down there. Our favourite feature has to be Papa Smurf’s House, a mushroom-shaped coral formation that’s just fun to swim around. In summer, the silverside swarms are so thick they blot out the sun, bringing in tarpon and jacks, a real spectacle. You'll often find schoolmaster snappers hanging out, and we’ve spotted a grumpy-looking green moray eel more than once. Keep an eye out for the smaller stuff too, we've had good luck finding blennies and jawfish tucked into the sand patches between coral heads. It’s a site that rewards slow exploration, best for divers who enjoy poking into every corner.
