Con Dao Island Guide: Flights, Ferries, Costs and Best Time

Is Con Dao Island worth visiting?

Yes, if you want quiet beaches, diving, turtle nesting and Vietnam's best-known prison history in one small place. No, if you want nightlife, big resorts or a cheap beach week. Con Dao is costly to reach, strictly protected and quiet by design, and most visitors stay three to five days.

Con Dao is a group of 16 islands and islets, most of them protected as Con Dao National Park. Con Son, the main island, has the only town. The archipelago now belongs administratively to Ho Chi Minh City, after the old Ba Ria - Vung Tau province merged into it, so older guides list the wrong province. French authorities began using the islands as a prison in the 1860s, and the camps ran until 1975. Estimates put the number of prisoners who died there at around 20,000. The prison museum is heavy going for young children.

How to get to Con Dao Island: flight or ferry?

The fastest way is a 50-minute flight from Ho Chi Minh City, from about 1,070,000 VND (~41 USD) one way on regular dates. The ferry costs less and takes longer: roughly 2 to 2.5 hours from Tran De near Soc Trang, or 3 to 4 hours from Vung Tau, plus the road to the port.

Flights to Con Dao Airport (VCS) are flown by Vietnam Airlines and its subsidiary VASCO on ATR 72 turboprops, because the airport only takes small aircraft. Hanoi and Can Tho also have direct flights. Fares jump on weekends and holidays, so book early and keep the return flexible.

The ferry has two main starting points. Tran De port, about 35 km east of Soc Trang city, has the shorter crossing, run by PhuQuoc Express and Superdong. From the port city of Vung Tau, PhuQuoc Express runs the larger Thang Long catamaran, with a 7:30 departure and a 13:00 return in the 2026 summer schedule and no sailing on Mondays. From Ho Chi Minh City the Vung Tau route takes five to six hours door to door: two to two and a half hours by road, then roughly three hours at sea.

How to book Con Dao ferry tickets

You can book on the operator's own website (PhuQuoc Express, Superdong or Con Dao Express) or through a booking platform that sells the same sailings. Wherever you book, make sure you receive an e-ticket or confirmation email before the travel day, and check the timetable again in peak season.

1. Compare timetables for your date: Vung Tau has a morning departure and an early afternoon return, while Tran De has more sailings.
2. Switch the operator's website to English before entering your dates.
3. Choose economy or VIP, then enter names exactly as printed in your passport; staff check IDs at the pier.
4. Pay online or at the operator's office and save the e-ticket or QR code offline, since signal at the pier can be weak.
5. Reconfirm the sailing the day before and that morning from August to November, when storms can cancel boats.
6. Arrange pickup from the pier. Buses and vans cover the road from Ho Chi Minh City to Vung Tau, and if you prefer a fixed price you can ask Sondax for a private car to the port.

How much does a trip to Con Dao cost?

Plan on 100 to 200 USD a day per person for a mid-range stay, before flights. Rooms are the biggest cost, from about 700,000 VND (~27 USD) in town to around 28 million VND (~1,080 USD) a night at the top resort, and getting here adds roughly 12 to 80 USD each way by ferry or plane.

How many days do you need on Con Dao Island?

Three days is enough for the prison sites, a beach day and one boat trip. Four or five days add a turtle night, a jungle walk or diving. With only two nights the trip works, but one delayed flight or cancelled ferry can swallow most of it.

• Day 1: arrive, rent a motorbike and ride the coastal road to Dam Trau Beach for sunset.
• Day 2: the museum, Phu Hai camp, the tiger cages and Hang Duong Cemetery (about half a day).
• Day 3: a boat trip to Bay Canh Island with snorkeling.
• Day 4: the Ong Dung trail or a dive; day 5 as a weather buffer.

Most trips connect through Ho Chi Minh City, so a spare night there is sensible. Our guide to what to do in Ho Chi Minh City covers one or two days.

Best time to visit Con Dao Island

The best time to visit Con Dao for calm seas and clear water is March to May. June to September suits diving and turtle nesting but brings daily showers. November to February is dry but rougher, and storms from August to November can pause ferries for days, so keep a spare day.

Diving is usually best from March to September, and visibility of about 15 to 20 metres is reported in July even in the rainy season. Turtles nest from roughly April to October, peaking from June to September. Our team's advice to friends is to pick the month for the activity first, because a turtle week and a beach week are different trips. For how the wet season plays out across the south, see how the rainy season changes by region.

Beaches are quiet and mostly undeveloped, with few facilities. Dam Trau Beach, close to town, is the usual sunset stop.

Con Dao vs Phu Quoc: which island suits you?

Choose Con Dao for diving, turtles, prison history and quiet roads. Choose Phu Quoc for big resorts, nightlife and easy flights. Con Dao has a small airport for ATR 72 planes and a handful of ferry sailings a day, while Phu Quoc has an international airport and many more places to stay.

If resorts and beaches are the priority, read about Phu Quoc's beaches and resorts first.

Things to do on Con Dao Island

Con Dao is best known for the prison camps where an estimated 20,000 people died between the 1860s and 1975. One ticket of 40,000 to 50,000 VND covers the museum and the main sites, and a half day is enough for most visitors. The park, the turtles and the reefs fill the rest of the stay.

Con Dao prison sites and museum

One ticket covers five sites: Con Dao Museum, the Governor's Palace, Phu Hai camp and the American and French tiger cage blocks. Buy it at the booth near the Governor's Palace, at the museum or online through the relic centre. The sites open daily with a lunch break, roughly 7:30 to 11:30 and 14:00 to 17:00. Start at the museum for context. We plan the prison before the beach, because it changes how the rest of the island feels.

Hang Duong Cemetery holds thousands of prisoners, many in unmarked graves. The best-known grave is that of Vo Thi Sau, a 19-year-old resistance fighter executed by French authorities in 1952. Many Vietnamese visitors leave flowers and incense, so dress modestly and keep your voice low.

Con Dao National Park and the Ong Dung trail

The national park covers most of the islands and the sea around them, with rainforest, mangroves, seagrass and coral. The Ong Dung trail takes about 25 to 40 minutes through forest to a pebbly beach with no facilities. Register at the park office on Vo Thi Sau street and pay 60,000 VND (~2.30 USD) for the adult walking ticket. Ask whether the trail is open that day, and wear shoes with grip, because old stone steps get slick after rain.

Con Dao turtle nesting on Bay Canh Island

Bay Canh Island is the main nesting site, and Con Dao turtle nesting runs from roughly April to October, peaking from June to September. The park runs an overnight programme with limited beds, reported at around 24 a night, so book six to eight weeks ahead. Rangers lead the viewing and use red light, so expect no flash and no touching. Day trips may include a hatchling release, depending on hatching, tides and park operations.

Con Dao snorkeling and diving

A half-day Con Dao snorkeling trip to Bay Canh and nearby islets runs about 900,000 to 1,200,000 VND (~35 to 46 USD) for groups of up to 12. Diving is usually best from March to September. Check whether the operator's price already includes marine park fees and tax, because it saves surprises at the pier.

Is Con Dao safe, and what about medical care?

Con Dao is calm and safe for visitors, but it is a small island with basic medical care, few ATMs and weather that can strand you. Carry travel insurance that covers medical evacuation, bring cash from the mainland, and keep a spare day at both ends of the trip.

The island has a medical centre for minor problems, and serious cases are normally moved to the mainland. Check that your policy covers motorbike riding and diving. Our first-timer checklist for Vietnam covers SIM cards, cash and insurance, and some small shops take cash only, so carry a backup.

Common mistakes on Con Dao Island

Most Con Dao problems come from planning, not from the island: no spare day, tickets bought too late, tight baggage limits or beach expectations the island cannot meet. These six checks keep the trip on schedule and the budget close to your plan.

• Booking the return for the day of an international flight. Keep a spare day; weather can delay flights and ferries.
• Leaving the turtle night too late. Beds are limited.
• Expecting one ticket to cover everything. The prison ticket and the park walking ticket are separate.
• Relying on one ferry operator in storm months. Services cut back from October to March, so check more than one timetable.
• Expecting resort beaches. There are few loungers and few facilities.
• Packing without checking baggage rules. ATR 72 flights have tight allowances.

FAQ

How do you get around Con Dao Island?

A rented motorbike at about 120,000 to 150,000 VND a day is the most flexible option, on a quiet coastal road with helmets required. Taxis and hotel cars cover the airport and pier, and an electric bus network was being launched in early 2026, so confirm routes locally.

Do you need a different visa for Con Dao?

No special visa applies: Con Dao follows the normal Vietnam entry rules for your passport. The 30-day exemption people mention belongs to Phu Quoc only, and US citizens still need a visa or e-visa unless an exemption applies. Check your passport on the official Vietnam e-visa portal before you book.

Can you visit Con Dao as a day trip from Ho Chi Minh City?

Technically yes by air, with a morning flight out and an evening flight back, but the prison sites alone take half a day and weather can cancel flights. A day trip leaves no time for beaches or the park, so most travellers stay at least two nights.
