Co To Island guide: fast boats from Van Don, beaches and storm caveats

Co To is the island you go to in the north-east when you want a beach rather than a cruise. It sits in the Gulf of Tonkin off Quang Ninh, at the far edge of Bai Tu Long Bay, and is now run as the Co To special zone. The national tourism site describes it as an archipelago of about 40 to 50 islands some 80 kilometres from the mainland, with wide beaches, forest and fishing villages, and warns that you will not find crowds of tourists or much nightlife. The catch is the sea: everything depends on fast boats from Van Don, and in storm season those boats stop.

Season and timing
The national tourism site calls summer and autumn the best time, with September and October the peak because they are still warm but less stormy than June and July; April and May are another good window. Winter is very quiet: Co To counted only about 13,000 visitors from mid-December 2025 to late March 2026, against a target of nearly 247,000 for the second quarter. Storms close the crossing: in July 2026 all boats were stopped for Storm Maysak.

The short answer

Stay two or three nights on the main island, in Co To town. Get to Van Don by expressway from Hanoi (about two and a half hours), take a fast boat from Ao Tien port, and spend your days on Hong Van and Van Chay beaches, at the lighthouse and on one licensed boat trip to the small islands such as Co To Con. If you cannot leave Hanoi at dawn, sleep a night in Cai Rong first and take a morning boat. Avoid a same-day trip: when we checked on 2026-10-03, the latest return Havaco listed was at 16:00. Book the return boat at the same time as the outward one, and leave a spare day in summer in case storms stop the ferries.

Why Co To, and when it is worth the crossing

Most visitors to Quang Ninh see its islands from the deck of a cruise boat. Co To is different: you sleep on an inhabited island, walk to the beach and eat seafood that came in on the morning boats. The national tourism site suggests it as a stay after a Ha Long Bay trip, because the ports for Co To are not far from Ha Long.

The local government counts more than 70 islands, large and small, in the archipelago, about 60 kilometres from the mainland; the national site says 40 to 50, about 80 kilometres out. Either way, the main island, Co To, is the one set up for visitors, with Co To town, hotels and homestays.

It is not empty all year. Co To received 513,913 visitors in 2024, according to the island's leaders in 2025, and almost all of them come in the warm months. The 2026 plan aimed at about 250,000 visitors in the summer season alone, and in summer 2025 Ao Tien port handled up to 16,000 passengers a day across all its island routes. If you want the beaches to yourself, aim for the edges of the season, such as late April and May or September and October, and avoid Vietnamese public holidays and summer weekends.

Beaches and the rocky coast

The national tourism site names four main beaches: Hong Van, Van Chay, Tinh Yeu (also called Tau Dam) and the beaches of Co To Con. Hong Van has the calmest water and is the one for a quiet swim or sunset; Van Chay, in the north of the island, is the place for waves, which the site says can reach 2 to 3 metres. In 2026 the special zone said it was upgrading Hong Van and Van Chay to Vietnam's national standard for tourist beaches and bringing Tinh Yeu up to it.

For rock rather than sand, the same site points to Mong Rong (Dragon's Claw), a 2-kilometre shore of stones that turn green with moss at some times of year, and the eroded rock reef at Cau My, best at sunrise.

In the middle of the island, a 2-kilometre lane lined with casuarina trees, known as the Love Road (Duong Tinh Yeu), is the classic late-afternoon walk or bicycle ride. Be aware that the coastal road of that name was badly hit by Storm Maysak in July 2026: the provincial newspaper reported that about 1.3 kilometres of it were seriously damaged, over 90 per cent of its length undermined or washed out. We could not confirm how much has been repaired, so ask your hotel before you plan around it.

Make time for the local food

What to eat and where to look

01

Steamed cu ky crab

Cu ky is a hard-shelled crab of these waters, usually simply steamed. The provincial newspaper lists steamed cu ky among the dishes islanders put in front of guests, cooked with little seasoning so the sweetness of the seafood comes through.

Where to look
Seafood restaurants in Co To town, or buy at the market or the harbour and have your hotel cook it.
Fit it into your day
The centre of a shared seafood dinner on your first night.

Shellfish; seafood is sold by weight, so agree the price per kilogram and check the weight before it is cooked.

02

Sa sung (peanut worm)

The provincial newspaper calls sa sung one of Co To's signature foods: grilled or stir-fried, it is sweet, rich and chewy. Dried, it is also the gift visitors most often take home.

Where to look
Restaurants and dried-seafood shops in Co To town; the national tourism site lists it among the island's unusual specialities.
Fit it into your day
A small plate with dinner, or a bag of the dried kind on your last morning.

Expensive and sold by weight; buy from an established shop.

03

Jellyfish salad (nom sua)

Prepared jellyfish tossed with herbs, green mango, carrot and crushed roasted peanuts, dressed with lime or vinegar, chilli and garlic. The provincial newspaper describes it as a cool, crunchy dish for hot days.

Where to look
Seafood restaurants in Co To town.
Fit it into your day
A starter before grilled seafood, or a light lunch after the beach.

Contains peanuts; ask for less chilli if you need to.

04

Grilled oysters with spring-onion oil and the harbour catch

Oysters grilled with spring-onion oil, squid salad and boiled snails are standard on island menus, according to the provincial newspaper. It also suggests going to the market, or to the harbour early in the morning or late in the afternoon when the fishing boats come in, to choose your own seafood; many homestays will cook it or set up a beach barbecue.

Where to look
The morning market and the harbour in Co To town, and your homestay or hotel.
Fit it into your day
Buy in the late afternoon, then a beach barbecue at dusk.

Shellfish should be eaten fresh and well cooked; settle the cooking charge with your hotel in advance.

The lighthouse and the Ho Chi Minh memorial

The Co To lighthouse stands on a forested hill about 5 kilometres from town, 100 metres above the sea, and dates from the late 19th century, according to the national tourism site. It is the island's best viewpoint. The keepers live there; if they let you climb the 72 steps of the spiral staircase, take your shoes off, because rainwater for drinking is collected from those steps.

In town, the Ho Chi Minh memorial area marks the president's visit to the island on 9 May 1961. Nhan Dan newspaper notes that Co To is the only place where he agreed to have his statue put up during his lifetime; the memorial was begun in 1968, became a national relic in 1997 and was ranked a special national relic in 2022. The square in front of it is where the island holds its events, and in 2026 the special zone made a flag-raising ceremony there a visitor programme.

The island also has a farming side that day-trippers miss. The provincial tourism portal described visitors in 2026 planting rice, leading cattle out and digging sweet potatoes with island farmers, part of a push to show Co To as more than a beach.

Co To Con, Thanh Lan and the small islands

Just off the main island lies Co To Con (Little Co To). The national tourism site says it is uninhabited and you cannot stay overnight, but you can go by boat for a day on its white sand and snorkel in clear water; one side is quiet and the other gets busy in peak season.

Thanh Lan island, about 2 kilometres from the main island, has forest and sedimentary rock formations, and smaller islets such as Hon Ca Chep (Carp islet), Hon Su Tu (Lion islet) and Hon Bay Sao are reached by boat. In April 2025 the then Co To district approved a pilot scheme, running until the end of 2026, for water sports and eight island-sightseeing routes linking Co To Con, Hon Ca Chep, Hon Su Tu, Hon Bay Sao, Hon Dong Nam, Thanh Lan and Tran island, with kayaking, jet skis, parasailing and coral diving at the main beaches. The provincial tourism portal publishes the list of travel companies approved to run these tours; book with one of them rather than an unlicensed boat.

New for 2026 are trips to sea-farming rafts around Hon Ngang and the nearby islets, where the provincial newspaper says visitors can feed fish, help with harvests, fish for squid, kayak or paddleboard and eat seafood on the raft. Because the pilot scheme ends with 2026, check what is running when you go.

Getting there: Ao Tien port, tickets and the weather

Fast boats leave from Ao Tien port in Van Don; the national tourism site also lists Cai Rong in Van Don and Tuan Chau in Ha Long as departure points, and the ferry company Havaco's booking form includes routes from both. From Hanoi, the expressways through Ha Long reach Van Don in about two and a half hours, according to the government news portal.

When we checked on 2026-10-03, Havaco listed Ao Tien – Co To departures at 07:00, 10:00 and 13:00 and returns from Co To at 10:00, 13:00 and 16:00, at 350,000 dong one way in standard class and 500,000 dong in VIP, with a child fare of 200,000 dong. Ka Long, another operator, told passengers to buy the Ao Tien port fee of 50,000 dong before boarding. Havaco advertises its crossing at about 60 minutes and Ka Long at about 1 hour 15 minutes. Times and fares change by season and operator, so book on the operator's own site, and avoid tickets offered on social media, which Ka Long warns can be scams.

Weather is the real constraint. On 3 July 2026 the province's waterways port authority ordered all boats to stay in port from 17:00 ahead of Storm Maysak; that day the special zone ran 18 sailings to take 3,147 passengers back to the mainland, and the boats only resumed on the afternoon of 5 July, when 10 sailings brought more than 1,700 visitors home. In the June to October storm season, keep a day spare, watch the forecast, and expect your hotel and boat company to tell you if sailings are cancelled.

Two practical notes. Carry ID: passengers' identity details are checked at the port, and foreigners should bring their passport. And bring a refillable bottle and bag: the national tourism site asks visitors not to bring plastic bottles or bags, and in 2026 the special zone set a target of removing single-use plastic from hotels, restaurants and beaches.

Practical questions

How do I get to Co To Island from Hanoi?

Drive or take a transfer to Van Don, about two and a half hours by expressway, then a fast boat from Ao Tien port. When we checked on 2026-10-03, Havaco listed departures at 07:00, 10:00 and 13:00 and said the crossing takes about 60 minutes.

How many days do I need on Co To?

Two or three nights. That gives you a full day for the beaches and lighthouse and one for a boat trip to Co To Con or the small islands, with some slack if the weather turns.

Can I visit Co To as a day trip?

Not sensibly from Hanoi. The first boat leaves Ao Tien in the morning and, when we checked, the last Havaco return left Co To at 16:00, so you would have only a few hours on the island after a long journey.

What is the best time to visit Co To?

The national tourism site recommends summer and autumn, with September and October the peak because they are warm but less stormy than June and July, and April and May as another good time.

What happens if a storm comes while I am on the island?

Boats stop. In July 2026, sailings were halted from 3 July for Storm Maysak and only resumed on the afternoon of 5 July, when the special zone ran extra boats to take visitors home. Keep a spare day, and book flights out of Hanoi with a margin.

Can I stay on Co To Con?

No. The national tourism site says Co To Con is uninhabited and overnight stays are not allowed; visit it by boat for the day.
