The boat slips from An Thoi harbor with the island chain sliding aft like a line of low cliffs; salt spray and the rumble of the engine set the tempo. You stand on the foredeck watching turquoise deepen into cobalt as the captain eases toward Hon Kim Quy, where shallow coral gardens strain to catch the sun.

The boat slips from An Thoi harbor with the island chain sliding aft like a line of low cliffs; salt spray and the rumble of the engine set the tempo. You stand on the foredeck watching turquoise deepen into cobalt as the captain eases toward Hon Kim Quy, where shallow coral gardens strain to catch the sun.
Southern Phu Quoc sits on a fringe of the Gulf of Thailand where limestone and older sedimentary beds meet younger marine deposits—an uncomplicated geology that produces wide sand spits and sheltered bays. The local fishing culture of An Thoi has long mixed with small-scale pearl farming and seasonal sea cucumber harvests; today tourism shares the water with working boats.
Expect three distinct snorkeling stops: the reef flats around Hon Kim Quy with compact coral heads and damselfish, the clearer drop-offs at Gam Ghi that invite longer swims, and the calm, sandy shallows of May Rut perfect for beginners. Guides brief the group, rig masks, and point out key species and fragile corals.
Practical notes: the trip is a full 8-hour day with hotel pickup from Duong Dong, an English-speaking guide, bottled water, and lunch on board. Bring a fit snorkel mask and fins, reef-safe sunscreen, a light rashguard, and a waterproof bag for valuables. Swim skills are required; life jackets are provided. Time your visit for morning departures when winds are light and visibility peaks.
On the return, the harbor lights of An Thoi reappear and the day’s small discoveries—turtle tracks, a banded coral shrimp—feel earned but within reach for most travelers.
easy.
8 hours.
Light to moderate fitness; must be comfortable swimming short distances and getting on/off a boat repeatedly.

Hotel pickup in Duong Dong, boat transfers, English and Vietnamese guides, bottled water, and onboard lunch are included.
Boat legs are typically short—10–30 minutes each—depending on sea conditions and the day's exact stopping pattern.
Children can join if they are comfortable in the water and accompanied by a guardian; check age limits with the operator and request life jackets as needed.
The An Thoi archipelago has long been a seasonal fishing and maritime trading area; recent decades have added tourism but local boatbuilding and fishing persist.
Operators increasingly follow reef-friendly practices—limit anchor use, brief visitors on not touching corals, and encourage reef-safe sunscreens to reduce local impact.
