The An Thoi Archipelago consists of a cluster of islands and islets scattered across the clear waters south of Phu Quoc. Each offers a slightly different coastal landscape, from sandy beaches and palm-fringed shores to rocky formations and colourful underwater habitats. Hon May Rut is popular for its beach scenery, while Hon Gam Ghi is known for snorkelling around coral reefs. Hon Thom, the largest island in the group, can be reached by a spectacular sea-crossing cable car that offers panoramic views of the surrounding islands.

Exploring the archipelago by speedboat or tour boat is one of the most rewarding experiences in southern Phu Quoc. Typical excursions combine several island stops, allowing visitors to swim, snorkel among tropical fish, relax on sandy shores or simply enjoy the scenery from the water. Many tours include lunch featuring fresh seafood and local dishes, adding a taste of Phu Quoc’s coastal cuisine to the day. Activities and stops vary by operator and sea conditions.

The period from November to April generally offers the most favourable conditions for island-hopping, with calmer seas and better underwater visibility. Morning departures are often a practical choice, although all trips remain weather-dependent. Visitors can begin their excursion at An Thoi Harbour and combine the archipelago with nearby attractions such as Khem Beach, Sao Beach or Sunset Town for a fuller exploration of southern Phu Quoc.
