Molasses Reef - Florida Keys

Molasses Reef. You hear the name a lot, and for good reason. It’s one of those spots in the Keys that consistently delivers, a solid pick whether you’re shaking off dive rust or just want a reliably good day underwater. We love the variety here; it’s not just one big reef, but a collection of distinct spur-and-groove formations, each with its own character. Drop in near the ‘Winch Hole’ mooring, and you’ll often find schools of jacks circling, their silver flashes catching the light. We’ve spent whole dives just watching a single Lancer Stargazer buried in the sand, eyes peeking out, or trying to spot a shy Key Worm Eel tucked into a crevice. The reef itself feels alive, with angelfish weaving through the corals and sergeant majors darting everywhere. Visibility can be a real treat, often pushing 25 meters, especially on an incoming tide. Our favourite spot is usually around the shallower ledges, where the light plays beautifully off the coral heads and you’re more likely to catch a glimpse of a tiny Colon Goby. It’s a busy reef, yes, but for good reason – it’s just plain good diving. It suits anyone looking for a classic Florida Keys reef experience, full of fish and healthy corals.
