A warm, salt-tilted wind meets the bow as the speedboat slips out of An Thoi Harbour, palms blurring into blue. The sea here dares you forward: shallow reefs pushing colorful life into view, beaches that accept footprints like a quiet audience. Over eight to ten hours you’ll race between islands, step onto pearly sand, and lean over a mask to watch fish navigate coral rooms.

A warm, salt-tilted wind meets the bow as the speedboat slips out of An Thoi Harbour, palms blurring into blue. The sea here dares you forward: shallow reefs pushing colorful life into view, beaches that accept footprints like a quiet audience. Over eight to ten hours you’ll race between islands, step onto pearly sand, and lean over a mask to watch fish navigate coral rooms.
Phu Quoc’s islands are products of recent geological uplift and coral accretion; Gam Ghi and the surrounding reefs are built of branching corals and boulder formations that host anemones, butterflyfish and small reef sharks. The archipelago sits along Vietnam’s Gulf of Thailand trade routes, with An Thoi historically a fishing and boat-building hub — today it’s the launch point for day trips and pearl-farm visits that illustrate local maritime culture.
Expect short hops by speedboat (roughly 10–40 minutes between stops), beach time on Mong Tay and May Rut, guided snorkeling over Gam Ghi’s shallows, and optional sea-walking experiences. Lunch is served ashore, and life jackets and basic snorkeling gear are included; fins may not fit children. Seas can be smooth or choppy — plan for spray and sun.
Practical guidance: wear reef-safe sunscreen and a UV shirt, keep hydrated, and bring a dry bag for electronics. If you’re prone to seasickness, take prevention before boarding. The tour suits moderately fit travelers comfortable entering and exiting a moving boat and swimming in open water. Respect marked reefs, follow guides’ briefings, and carry cash for small island purchases.
