Phu Quoc and Con Dao are both southern Vietnamese islands, both ringed by clear water, and both genuinely worth visiting. Beyond that, they are almost opposites. Phu Quoc is Vietnamβs most developed island resort - busy, accessible, and full of infrastructure for every budget. Con Dao is remote, tightly controlled by a national park, and deliberately harder to reach. Choosing between them depends on what you want from an island.
The Islands
Phu Quoc is Vietnamβs largest island, roughly the size of Singapore, sitting off the southwest coast near the Cambodian border. It has been developing rapidly since gaining visa-free international status in 2014, and now has an international airport, a Six Senses resort, a VinWonders theme park, a safari park, and a full strip of beach hotels along Long Beach. Despite this, the north and east coasts remain largely forested and the national park covers more than half the islandβs interior.
Con Dao is an archipelago of 16 islands 230km southeast of Ho Chi Minh City. The main island, Con Son, covers 57sq km and holds the only settlement - Con Son town, a former French and American penal colony that imprisoned Vietnamese political prisoners from 1862 through 1975. The national park covers 80% of the land and marine area. There is no fast ferry. The island is reached only by small propeller aircraft from HCMC or Can Tho, and the limited capacity keeps visitor numbers manageable year-round.
Beaches
Phu Quoc: Long Beach (Bai Truong) on the west coast is the main swimming strip - a 20km stretch with calm, clear water, beachfront bars, and a range of hotels from guesthouses to international chains. Sao Beach (Bai Sao) on the south coast is the most photographed: fine white sand and water that shifts from turquoise to deep blue within metres. Ong Lang Beach on the northwest is quieter, lined with boutique resorts set back from the treeline. The east coast is largely undeveloped.
Con Dao: The beaches here are smaller, less manicured, and almost always empty. Dat Doc Beach on the northeast coast is the main accessible beach from Con Son town - a wide bay with calm, dark-blue water. Lo Voi Beach, reached by motorbike along a forest road, is one of the most beautiful beaches in southern Vietnam: a crescent of pale sand backed by jungle with almost no other visitors. Bay Canh Island, reached by boat from the national park office, has protected nesting beaches and excellent snorkelling.
Verdict: Phu Quoc delivers more varied beach options with better infrastructure for sunbathing and watersports. Con Daoβs beaches are more dramatic and emptier, but require more effort to reach.
Diving and Snorkelling
Phu Quoc has solid diving around the An Thoi archipelago to the south. The reefs around Hon Thom (Pineapple Island) and the surrounding small islands have coral gardens with visibility of around 10-15 metres in the dry season. Dive operations on Phu Quoc are well-established; two-tank dives run approximately USD 55-80 as of 2026.
Con Dao is regarded as the best diving in southern Vietnam. The marine park protects reefs that see far fewer divers than Phu Quoc or Nha Trang, and the coral is in noticeably better condition. Visibility in peak season (July-September) reaches 15-20 metres. Two-tank dives cost approximately USD 32-60 as of 2026 - slightly cheaper than Phu Quoc despite the more remote setting. The dive season runs April-October; Con Dao Dive Center and Rainbow Divers Con Dao are the main operators.
Verdict: Con Dao wins clearly for diving quality and reef health. Phu Quoc is better for casual snorkelling on a day trip without needing to plan around dive seasons.
Getting There and Around
Phu Quoc has an international airport (PQC) with multiple daily flights from HCMC (1 hour, from approximately USD 20 as of 2026) and Hanoi (2 hours, from approximately USD 35). Budget carriers Vietjet and Bamboo Airways compete with Vietnam Airlines, keeping fares low and availability high. You can also reach Phu Quoc by ferry from Ha Tien on the mainland (1-1.5 hours) or from Rach Gia (2.5 hours). Getting around the island is easiest by motorbike rental (approximately USD 8-12 per day).
Con Dao is reachable only by air. Vietnam Airlines and VASCO operate ATR-72 flights from HCMC (45 minutes, approximately USD 32-100 as of 2026) and Can Tho (35 minutes). The aircraft hold around 70 passengers and flights fill fast - book at least one to two weeks ahead in peak season. Once on the island, motorbike rental costs USD 4-6 per day and is the only practical way to explore beyond Con Son town. There is no fast ferry service from the mainland.
Costs
Phu Quoc suits most budgets. Budget travellers staying in guesthouses and eating at local stalls spend approximately USD 30-50 per day. Mid-range visitors staying in beach hotels with AC and eating at proper restaurants budget USD 70-120 per day. Luxury resorts and the Six Senses push well above USD 300 per night.
Con Dao costs more at every level. The remote supply chain and limited accommodation competition mean food is 30-50% more expensive than mainland Vietnam. Budget guesthouses in Con Son town start around USD 16-32 per night. The mid-range Con Dao Resort (Saigon Con Dao hotel) runs USD 60-160. The ATC Hotel in Con Son town offers reliable mid-range rooms at USD 24-56 per night. The Six Senses Con Dao resort charges USD 400-1,600+ per night for private pool villas, and is one of the highest-regarded eco-resorts in Southeast Asia. Overall daily budgets: USD 24-48 budget, USD 60-160 mid-range.
Verdict: Phu Quoc is more affordable and more flexible on budget. Con Dao costs more at every tier but delivers value in remoteness, nature quality, and crowd-free experience.
Accommodation Highlights
Phu Quoc has accommodation at every price point: backpacker hostels along Long Beach from USD 10 per dorm bed, family guesthouses from USD 25-40, beach resort hotels from USD 50-120, and luxury properties including the JW Marriott, Intercontinental, Radisson Blu, and Premier Village.

Con Dao has three practical accommodation tiers. Budget: family guesthouses in Con Son town from USD 16-32 per night - book ahead, options are limited. Mid-range: the Con Dao Resort on the main beach at USD 60-160, and the ATC Hotel in town at USD 24-56. Luxury: Six Senses Con Dao at USD 400-1,600+ per night, requiring months of advance booking in peak season (July-October). Search Con Dao hotels on Booking.com.
The Con Dao History Dimension
Con Dao carries a historical weight that Phu Quoc does not. The prison complex - Phu Hai, Phu Son, and the notorious βtiger cagesβ used to hold political prisoners in isolation - is preserved as a museum and is free to enter (open daily 07:00-11:00 and 13:30-17:00). The museum is one of the most significant historical sites in Vietnam and gives Con Dao a dimension that goes well beyond beach tourism. Travellers interested in the Vietnam War, colonial history, or Vietnamese political history will find the visit genuinely affecting.
Sea Turtles
Con Dao is one of the most important green sea turtle nesting sites in Southeast Asia. From July to October, turtles come ashore at night to lay eggs on protected beaches - the national park runs a guided turtle watch program that allows visitors to observe nesting without disturbing the animals. The experience is available only through the national park office; places are limited. This is one of the best wildlife encounters available anywhere in Vietnam.
Who Should Go Where
Choose Phu Quoc if you want a beach holiday with easy logistics, a full choice of accommodation, nightlife and restaurants, watersports without planning ahead, and a straightforward flight from any major Vietnamese city. It suits families, couples on shorter itineraries, and travellers who want relaxation without logistical challenge.
Choose Con Dao if you want excellent diving, empty beaches, turtle watching, serious historical content, and a quieter island atmosphere with no nightlife and few crowds. It rewards travellers who plan ahead, are comfortable with limited infrastructure, and want something further off the tourist circuit than Phu Quoc.
Both islands can be combined in a 10-day southern Vietnam itinerary alongside Ho Chi Minh City and the Mekong Delta. Con Dao works well as a 3-day extension added to an HCMC base; Phu Quoc is easy to combine with Ha Tien and a Cambodian border crossing.
