The sun hits the harbor like a promise, and the boat slips toward the open water — An Thoi’s limestone outcrops sliding astern as the engine finds its rhythm. Within an hour you’re anchored over a mosaic of coral heads; masks on, fins whispering as the reef pulls you into a different pace.

The sun hits the harbor like a promise, and the boat slips toward the open water — An Thoi’s limestone outcrops sliding astern as the engine finds its rhythm. Within an hour you’re anchored over a mosaic of coral heads; masks on, fins whispering as the reef pulls you into a different pace.
These islands belong to the An Thoi archipelago at Phu Quoc’s southern tip, a place shaped by uplifted limestone, shifting sandbanks and generations of fishing communities. The reef systems here are patchy but lively: hard and soft corals intersperse with seagrass beds, and local guides point out signs of pearl farming and traditional longline fishing that still support island life.
Expect three main snorkeling stops — Kim Quy (a clarity-prone bowl), Gam Ghi (shallow coral gardens) and Hon May Rut (sandy beaches for lunch and a post-swim rest). The day is practical: hotel pickup, safety briefing, guided snorkeling rotations, an onboard Vietnamese lunch and a return transfer in the afternoon.
Plan for sun, salt and short swims between boats and reefs. Use reef-safe sunscreen, bring a snug mask and a rash guard, and hydrate; currents can be playful and visibility varies with tide. If you get seasick, take medication before boarding. Respect the reef: no standing on coral, no taking shells.
By day’s end you’ll know the rhythm of An Thoi’s water — direct, generous and alive — and carry a clear sense of why protecting these reefs matters.
