Phu Quoc 2026: Vietnam's Largest Island — Beaches, Diving and Resorts

Phu Quoc is a 574 sq km island in the Gulf of Thailand, 45km off the Cambodian coast and 15km from mainland Vietnam’s Ha Tien. It is Vietnam’s largest island and its fastest-developing resort destination. Visa-free entry for up to 30 days (regardless of nationality) has made it an international beach destination, and a resort corridor along the west coast has grown rapidly since 2015. Data connectivity on the island is good in the main resort areas — an Airalo eSIM activated before arrival is the easiest way to have data the moment you land, without queuing for a local SIM at the airport.

What the island offers

The west coast has the best beaches — Long Beach (Bai Truong) runs 20km along the southwest, with calm, clear water and good sunset views. The north has wilder terrain, peppercorn farms, and fishing villages. The interior is a national park (93,000 ha, UNESCO Biosphere Reserve) with limited but existing trekking. The south has Sao Beach, consistently rated among Vietnam’s finest sand beaches.

The diving is the best in mainland Vietnam’s accessible offshore islands — not comparable to world-class sites, but with reasonable coral coverage and visibility. The An Thoi archipelago in the south is the main dive area. Island-hopping boat trips and snorkelling excursions can be booked through Tiqets with confirmed tickets before arrival.

Development reality

Phu Quoc has changed substantially since 2015. Vinpearl and Vingroup have built a large resort and entertainment complex on the north coast. The Grand World complex near Duong Dong town caters primarily to domestic and Chinese tourism. The southern resort corridor is where most international luxury hotels sit.

The island retains its original character in the north and interior — pepper farms, fish sauce factories (Phu Quoc nuoc mam is a protected designation), and fishing villages — but the beach areas have heavy construction. New visitors should research which part of the island suits their preference before booking.

Costs

Budget daily: ₫400,000–700,000 ($16–28). Mid-range: ₫800,000–2,500,000 ($32–100). Luxury resorts: ₫3,000,000–20,000,000+ ($120–800+). Beer at a beach bar: ₫30,000–60,000 ($1.20–2.40). Seafood meals average higher than mainland Vietnam.

Seasons

The dry season (November–April) is the main travel window — calm seas, clear water, and beach conditions. May–October brings the southwest monsoon: rough seas, periodic heavy rain, and reduced diving visibility. Some resorts close or reduce operations June–September. The island is viable year-round but the experience varies significantly.
