Phu Quoc Island

Duong Dong · Kien Giang Province · Vietnam

Phu Quoc Island sits in the Gulf of Thailand off Vietnam's southwestern coast, and while it may not appear on top dive destination lists, the diving around its southern archipelago offers a charm that more famous locations often lack. This is intimate, relaxed reef exploration where rewards come from paying attention to the small things, and the marine life reveals itself to patient eyes. I rode a longtail boat from An Thoi to a cluster of rocky islands surrounded by clear water. The descent was gentle, down a mooring line to a coral-covered slope at 10 metres. The reef was a patchwork of healthy hard corals, soft corals, and sponges on volcanic rock. Within moments my guide pointed at a thorny seahorse clinging to a red gorgonian fan, its tiny body curled and swaying with the gentle surge. Over two dives that afternoon, the macro life delivered consistently. Nudibranchs in astonishing variety crawled across coral surfaces. Mantis shrimp peered from burrows with their extraordinary compound eyes. Cuttlefish hovered at the reef edge, cycling through colour changes. A blue-spotted ray lifted from a sandy patch and glided away. The fish life, while not overwhelming in biomass, was varied and engaging. Schools of batfish hung in the water column above coral bommies. Clownfish defended anemone territories. Scorpionfish sat motionless on coral heads, their camouflage so effective that the guide had to physically point my mask toward them. Phu Quoc's diving benefits from the An Thoi archipelago's geography. The cluster of islands creates sheltered pockets where coral growth flourishes. Each island has its own character: rocky walls with swim-throughs, sandy slopes with isolated bommies, and seagrass beds where seahorses are found reliably. The visibility is the one honest caveat. On good days it reaches 20 metres, on average days it hovers around 10 to 12 metres. But the nutrient-rich water that limits visibility fuels the prolific small-creature life that makes Phu Quoc rewarding for divers who value discovery over spectacle.
