Con Dao is the part of southern Vietnam that most visitors never see, and that is exactly why some travellers go. It is a small group of islands far out in the sea south of the mainland, with no bridge, no road and no overland route. You arrive by air or by fast ferry, you stay on the main island, and you leave the same way. Everything about the destination follows from that isolation: the calm, the higher prices, the short list of things to do and the need to plan the trip as a proper stay rather than a stop.
This page explains what Con Dao is, how it differs from the island people often confuse it with, how to reach it, when to go and what a sensible budget looks like. It stays deliberately cautious: we describe what the islands are known for in broad terms and we leave out details we cannot stand behind.
An isolated archipelago, not a day trip
On a map of southern Vietnam, Con Dao looks close enough to Ho Chi Minh City to be an excursion. It is not. Ho Chi Minh City sits inland on the Saigon River, and the islands lie out at sea beyond the coast, reachable only across open water or through the air. There is no road, so there is no coach, no private car and no “drive and board a short boat” combination of the kind that makes a Mekong Delta outing possible from the city.
The practical consequence is simple. If you have a single free day in Ho Chi Minh City, Con Dao is not a candidate. The Cu Chi Tunnels, the Mekong Delta and other day trips from the city are what a day buys you. Con Dao belongs to the part of your trip where you have decided to spend several days on an island and accept the travel that comes with it.
Even a flight, which is the quick option, changes your day: you travel to the airport, fly, transfer to the main settlement and only then start your stay. A fast ferry takes much longer again and depends on the sea. Count the day of arrival and the day of departure as travel days with a little left over at either end.
Not Phu Quoc: two different islands
The confusion is understandable, because both are southern islands that appear on beach-holiday shortlists. They are not the same place, and treating them as interchangeable leads to disappointment.
| Con Dao | Phu Quoc | |
|---|---|---|
| Sea | Open sea south of the mainland | Gulf of Thailand, off the Cambodian coast |
| Size and infrastructure | A small group of islands with a modest main settlement | Vietnam’s largest island, with resorts, a large tourism offer and its own international airport |
| Airport | A small domestic airport | An international airport (PQC) |
| Type of stay | Quiet, nature-led, few distractions | Resort holiday with many hotels, restaurants and attractions |
| Reached by | Air or fast ferry only | Air or ferry |
Phu Quoc is a developed destination with international flights, a wide range of accommodation and plenty to do on a rainy afternoon. Con Dao has none of that scale. If you want a pool resort, a long menu of excursions and an easy international arrival, read the page on Phu Quoc instead. If you cannot decide between them, our comparison Phu Quoc or Con Dao sets the two side by side.
Do not use Con Dao as a stand-in for Phu Quoc on a tight schedule. The two are far apart, they sit on different coasts of the south and they do not connect to each other in any simple way.
What visitors come here for
We keep this short on purpose, because the honest summary is short. People come to Con Dao for the sea, the quiet and the nature.
- The sea. Snorkelling and diving are the main reasons to get in a boat. Visibility and conditions depend on the season and the weather, which is why the dry months matter.
- The calm. With no mainland crowds and a small main settlement, evenings are quiet. There is little nightlife and that is the point.
- Nature. The islands offer forest walks and peak hikes, and boat trips to smaller islands for birds and, with the right operator and timing, turtles.
Con Dao also has a history that many visitors read about before they travel. We do not summarise it here, because it deserves a dedicated source rather than a paragraph from a travel planner. If it interests you, read up before you go and ask your hotel what is open and how visits are organised.
How to get to Con Dao
There are two realistic ways in. Neither is a day trip.
By air
Flying is the fast and most reliable option. Con Dao has its own small domestic airport, and flights run from the mainland, most commonly from Ho Chi Minh City, in roughly an hour. This is the same kind of short domestic hop described in our guide to domestic flights in Vietnam, but with fewer departures than the busy trunk routes, so book early in the high season and check the schedule rather than assuming a flight every few hours.
Remember the airport logic of the south: Ho Chi Minh City’s Tan Son Nhat (SGN) is close to the centre, around 7 km, so a morning flight is easy to catch from a District 1 hotel. Our explainer on Vietnam’s airports covers the main gateways and the domestic airports around the country.
By fast ferry
A fast ferry crosses to the islands from the mainland coast. It is slower than flying, it is sensitive to the sea state and it can be rough or cancelled in poor weather, especially in the wet months. The upside is cost and the feeling of arriving by sea. Plan on several hours for the crossing, plus the transfer to the departure port, and keep a buffer in your schedule on both ends. Departures and exact times change, so confirm with the operator or your hotel close to the date.
If you prefer to have everything arranged, there is a packaged option that includes the crossing: a three-day tour from Ho Chi Minh City by high-speed boat bundles the transport and activities into one booking. Read the itinerary carefully and check what is included before you pay.
Getting around once you arrive
The main settlement is small, and most visitors rely on a hotel transfer, a rented bicycle or scooter, or a local driver for the rest. Only rent a motorbike if you hold the right licence and valid insurance: many insurers refuse a claim otherwise, which matters far from a hospital. See our guide on renting a motorbike in Vietnam before you decide.
When to go: the southern two-season pattern
Con Dao follows the southern pattern, not the northern or central one. There is no winter. Temperatures sit around 25 to 35 °C all year, and the year splits into two seasons.
| Period | Season | What to expect |
|---|---|---|
| Roughly December to April | Dry | Best conditions for the sea, boat trips and hiking; March and April are the hottest |
| Roughly May to November | Wet | Short, often late-afternoon downpours; a rougher sea; more chance of cancelled boats and ferries |
For a first visit, aim for the dry months. They give the best odds of calm crossings and of boat excursions running as scheduled. In the wet season the islands are still green and quiet, but you accept that a ferry, a snorkelling trip or even a flight can be changed at short notice. If you travel then, leave slack at the end of the trip so that a delay does not cost you an international departure.
For the wider picture of weather and storms across the country, including the typhoon risk in other regions, read Vietnam’s rainy season and typhoons. A rule worth repeating: there is no single best month for all of Vietnam, and the south is not the north.
What to do on the islands
Con Dao is a small destination, so the list is short and best planned in advance. Your operator or hotel will tell you which excursions are running on the days you are there.
Snorkelling and diving
Boat trips from the main island visit nearby reefs and smaller islands. If you have never dived, a short half-day scuba and snorkelling outing is a reasonable introduction and does not commit you to a multi-day programme. Experienced divers should check certification requirements and equipment with the operator beforehand.
Our overview of islands and snorkelling trips in Vietnam puts these outings in context with other destinations.
Wildlife: birds and turtles
Two kinds of trip are popular with nature-minded visitors. One is a day trip to a smaller island for birdwatching and snorkelling, such as the Hon Trung birdwatching and snorkelling trip. The other is an overnight or two-day excursion built around turtles, for example the two-day turtle watching and snorkelling tour.
Wildlife is never guaranteed. Turtle nesting depends on timing and conditions, so ask the operator when nesting is likely and what happens if the trip cannot go ahead. Follow the guide’s instructions: do not use flash, do not approach animals and do not leave rubbish on the beach.
Hiking
The islands have forest and peak walks. Treks are listed for Nui Chua, So Ray and Vinh Dam Tre. The Nui Chua option is the most obviously demanding of the three, and a guided Nui Chua peak trek is the version most travellers will want if they like a longer, steeper walk. Start early, because the heat builds fast, carry plenty of water and wear proper shoes.
Quiet days
Do not underestimate the value of doing nothing. With a small town, a few quiet beaches and unhurried evenings, many visitors spend a day or two simply swimming and eating. Con Dao suits travellers who are comfortable with that rhythm. If you need constant activity, it will feel empty.
How long to stay
Plan at least two nights, and ideally three or four. Here is why:
- The arrival and departure days are partly lost to transport.
- Boat excursions depend on weather, so a spare day protects you from losing the main activity.
- A hike and a boat trip are enough for one or two active days, and a third day lets you rest.
A one-night stay makes the effort of getting there hard to justify. Travelling for four or five days is only worth it if you like the idea of slow island time. Fit it into your wider plan using how many days to spend in Vietnam, and keep the islands as an add-on to a southern route such as our southern Vietnam in one week itinerary.
What it costs: an honest order of magnitude
An island with no road access and a small tourism market is more expensive than a mainland town of comparable size. Boats, fuel and food all arrive by sea or air, and accommodation choices are limited, so the choice of room matters more than elsewhere.
As a rough guide for 2026, a day on Con Dao for one person, including a modest room, meals and one or two paid activities, falls between about 1,200,000 and 3,000,000 VND, which is roughly 500 to 1,250 NOK at about 28,000 VND to 1 EUR. Treat this as an order of magnitude. Prices change, the dong drifts slowly downward and a diving day or a private boat can push you above the upper figure.
Add the transport on top: a return flight or ferry from the mainland is often the single largest cost, and prices vary with the season and how early you book. For a wider picture of what to expect around the country, see the Vietnam travel budget guide.
Cash still matters on a small island. Hotels, dive operators and organised tours usually take cards, but small cafés and local shops may not, and cash machines are far fewer than in a big city. Bring enough dong with you from the mainland.
Practical points
- Booking. Book accommodation and transport before you commit to the island, especially in the dry season, when the limited number of rooms fills.
- Insurance. You are far from a major hospital. Take travel insurance that covers medical care and, if you dive or ride, those activities specifically.
- Visa. Entry rules depend on your nationality and change; check the official immigration portal or your government’s travel advice, and read our visa guide.
- Water and sun. Tap water is not drinkable anywhere in Vietnam, so use bottled or filtered water. The sun is strong at sea even on cloudy days.
- Emergency numbers. 113 for police, 114 for fire and 115 for an ambulance.
- Time zone and power. UTC+7 all year, no daylight saving; sockets are mainly Type A and C, 220 V.
How Con Dao fits with the rest of the south
Con Dao works best as a deliberate, separate chapter. A sensible arrangement is to see Ho Chi Minh City and the Mekong Delta first, then fly out for a few quiet days, and fly back for your departure. The other southern coastal places are different in character: Mui Ne is a sand-dune coast about 200 km north-east of Ho Chi Minh City, Vung Tau is a seaside town reachable from the mainland, and Phu Quoc is the larger, more developed island. None of them replaces Con Dao and Con Dao replaces none of them.
For the wider region, the overview of southern Vietnam places all of these side by side, and our best beaches in Vietnam guide helps if the real question is where to swim.

Con Dao travel questions answered
Can you visit Con Dao as a day trip from Ho Chi Minh City?
No. There is no road access, and reaching the islands means a flight or a fast ferry. Even by air, the transfers and check-in take a large part of the day. Plan at least two nights on the islands.
How do you get to Con Dao?
By plane from the mainland, most commonly from Ho Chi Minh City, in roughly an hour, or by fast ferry, which takes several hours and depends on the sea. Neither involves a road journey. Check schedules close to your date, because flights and sailings change.
Is Con Dao the same as Phu Quoc?
No. They are different islands with different airports, a different sea and a different kind of stay. Phu Quoc is Vietnam’s largest island, in the Gulf of Thailand, with an international airport and a large resort offer. Con Dao is a small, remote archipelago with a modest settlement and a quiet, nature-led atmosphere.
When is the best time to visit Con Dao?
Roughly December to April, in the dry season of the south. March and April are the hottest months. From about May to November the wet season brings short downpours and a rougher sea, which can disrupt ferries and boat excursions.
How much does a trip to Con Dao cost?
As an order of magnitude in 2026, about 1,200,000 to 3,000,000 VND per person per day on the islands, roughly 500 to 1,250 NOK, plus the flight or ferry. Island prices are higher than on the mainland, and dives or private boats cost more.
How many days do you need in Con Dao?
At least two nights, and ideally three or four. The arrival and departure days are partly consumed by travel, and boat trips depend on the weather, so a spare day is a sensible safeguard.
Can you drink the tap water on Con Dao?
No. Tap water is not drinkable anywhere in Vietnam. Use bottled or filtered water, including for brushing your teeth if you have a sensitive stomach.
