The An Thoi Archipelago lies to the south of Phu Quoc Island, Vietnam, positioned around 9°50′N and 104°05′E. The archipelago consists of 15 islands, of which only five are inhabited; the rest remain untouched, covered with forests, rocky hills, and surrounded by pristine seawater. Travelers who have set foot on these uninhabited islands often share the same impression: beautiful from afar, breathtaking up close, with soft white sand, crystal-clear water, and an immaculate, unspoiled landscape.
The total land area of the archipelago is roughly 7.2 km², concentrated mainly on Hon Thom Island, which is now part of the Phu Quoc Special Zone, An Giang Province under the new administrative structure.
Some of the most well-known islands include Hon Thom, Hon Dam Trong, Hon Dau, Hon Dua, Hon Gam Ghi, Hon Kho, Hon Kim Quy, Hon May Rut Ngoai, Hon May Rut Trong, Hon Mong Tay, Hon Roi, Hon Trang, Hon Vang, Hon Vong, and Hon Xuong.

Nature & Ecosystems
The sea around An Thoi is exceptionally deep and clear, reaching depths of up to 30 meters in certain areas. Hon Thom and Hon Roi boast vibrant coral gardens that serve as habitats for numerous marine species. Many local folklore stories are tied to island names such as Hon Kim Quy, Dam Ngoai, Dam Trong, and Hon Thom. According to tradition, several islands once served as temporary shelters for Nguyen Dynasty troops, and ancient shrines dedicated to mountain, forest, and sea deities can still be found today.
Along several beaches, naturally stacked rocks form unique shapes. Dry branches reaching out to the water’s edge and sea eagles—often called “storm birds” by locals—circling above the boats create an atmosphere of wild, dramatic beauty.
Experiences & Activities
A visit to An Thoi invites travelers to wander deep into the islands to explore pristine forests, steep trails, and hidden streams, offering a rare chance to experience landscapes completely untouched by human development.
The archipelago is also a paradise for snorkeling and scuba diving, home to nearly 20 species of hard and soft corals, sea anemones, and a wide array of colorful marine creatures.
Hon Thom in particular is famous for its night squid fishing experience. Local fishermen are always ready to guide visitors in catching fish, harvesting sea urchins from the rocks, and preparing fresh seafood dishes right on the spot. Most island residents make their living from the sea or from cultivating fruit trees on the hillsides; life remains simple, yet rich in authentic local charm.
Tourism Potential
With its untouched scenery, diverse ecosystems, and distinctive local culture, the An Thoi Archipelago holds enormous tourism potential. In the near future, investments from Kien Giang Province are expected to further unlock these natural advantages, paving the way for An Thoi to become one of Vietnam’s most captivating coastal destinations.
