    Turtle Alley, on Cayman Brac's northwest end, is one of those places that just makes you smile. It's a gentle drift along a miniwall that starts around 9 meters, then slopes down to a sandy bottom at 16 to 19 meters. The wall itself is painted with dense finger coral and the kind of hefty boulder brain coral we love to poke around in. Look closely, and you’ll spot those brilliant orangespotted filefish flitting about, and we often find quirky little imitator blennies peering out from crevices. The real draw, though, isn't just the turtles-though you will see them, often hawksbills cruising by-it’s the quality of the light here. When the sun hits the sand flats, it creates this ethereal shimmer, especially in the late morning. We’d suggest going then. Visibility averages 23 meters, which is plenty to appreciate the sheer volume of schoolmasters and mutton snapper holding formation. It’s a beautifully relaxing dive, perfect for photographers or anyone who just wants to soak up that classic Caribbean calm.
