    Boss Reef, or Bass Reef as we still like to call it, holds a special place. It’s right outside Grand Anse Bay, a stretch that once teemed with big fish before the fishing pressure got too intense. We find it’s a site best explored slowly, letting your eyes adjust to the subtle movements. Dropping in, the reef begins at around 6 meters, gently sloping to its deepest point at 19 meters. Visibility averages 16 meters, which is usually plenty to appreciate the details. Head towards St. George's and you'll navigate through more stony corals, a robust landscape. But veer closer to Quarantine Point, and the scenery shifts dramatically. Here, you'll glide past a colourful display of soft corals and sponges, a real treat for macro fans. We’ve had fantastic luck spotting Opossum Pipefish tucked away here, and the Pearl Blennies are always a joy to watch darting between crevices. On a good day, we've even seen Devilfish lurking in the shadows. It’s a site that rewards patience, perfect for photographers or those who just want a relaxed dive with a surprising amount of tiny life.

    Safety Notes

    Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
