Co To has grown steadily from a little-known fishing island into one of northeast Vietnam’s more talked-about island escapes, but it’s still small enough that a few days covers nearly everything worth doing. This guide focuses on the seven activities specifically worth building a Co To itinerary around, for travelers who have a long weekend or a few days off the mainland and want a clear, prioritized shortlist rather than an overwhelming list of every single beach and viewpoint on the island.

Before you go: Co To at a glance

A quick orientation before the list itself: Co To sits off Quang Ninh province and is reached by ferry from Cai Rong Port or the Ao Tien Cruise Terminal in Van Don district, a crossing of roughly 90 to 120 minutes depending on sea conditions. Most travelers reach those ports via a roughly three-hour bus or car ride from Hanoi, making Co To a realistic weekend or long-weekend trip rather than a day excursion. It’s grown steadily in popularity with domestic travelers over the past several years without tipping into the kind of overdevelopment you’ll find at bigger beach destinations, which is exactly why a focused list of seven activities, rather than an exhaustive one, still covers nearly everything worth doing.

1. Swim and unwind at Van Chay Beach

Van Chay (also written Van Chai) is Co To’s most famous stretch of sand, known for a wide shoreline and genuinely soft white sand that holds up to the island’s growing reputation. It’s the obvious first stop for most visitors and the easiest beach to reach from Co To Town, making it a sensible base for your first afternoon before you start exploring farther out. Plan at least half a day here; the water is calm enough for relaxed swimming rather than serious waves. A handful of simple seafront cafes line the edge of the beach, so you can easily turn a swim into a lazy few hours without needing to plan meals around a trip back into town. Early morning and late afternoon are the most comfortable times to be out on the sand, since the midday sun here offers very little natural shade.

2. Catch sunrise or sunset at Co To Lighthouse

The island’s lighthouse sits at a high point with genuinely panoramic coastal views, and it’s worth timing your visit around sunrise or sunset rather than the middle of the day. The climb up is short enough to manage even on a relaxed holiday schedule, and the payoff — open ocean in every direction with almost no other structures in view — is the single most-photographed moment most visitors bring home from Co To. Bring a light layer even in warmer months, since the exposed viewpoint catches a steady wind that the sheltered beaches below don’t, and give yourself at least thirty minutes to just sit and watch the light change rather than treating it as a quick photo stop.

3 & 4. Explore Cau My Cliffs and boat out to Co To Con Island

The Cau My cliffs, nicknamed “Dragon Claws” for their dramatically eroded rock formations, are Co To’s most distinctive natural landmark and worth a dedicated couple of hours to properly explore and photograph from multiple angles. Pair that with a short boat ride out to Co To Con, a small, uninhabited island just offshore that delivers a genuine escape-the-crowds afternoon even by Co To’s already-relaxed standards — bring your own snacks and water, since there’s no infrastructure once you land. Boat operators in Co To Town run this trip regularly in good weather, and it’s worth asking your guesthouse to help arrange a slot rather than trying to book it entirely on your own, since departures depend on both tide and sea conditions. Together, these two stops are the best way to see a side of Co To that goes beyond its beaches, and they pair naturally into a single half-day outing.

5. Visit the Ho Chi Minh Memorial and Co To Pagoda

For a change of pace from beaches and cliffs, the island’s Ho Chi Minh Memorial, marking a historic 1961 visit, and the nearby Co To Pagoda give a quieter, more reflective couple of hours. Neither site demands much time, but both add context to an island that’s easy to treat as purely a beach destination, and they’re an easy pairing with a slow morning or a break from the midday sun. The memorial in particular draws a steady trickle of domestic visitors for whom the 1961 visit carries real historical weight, which is worth keeping in mind as a reminder that Co To’s identity extends well beyond its current reputation as a beach escape.

6. Rent a motorbike and ride to the quieter beaches

Beyond Van Chay, Co To has several quieter alternatives worth a dedicated motorbike loop: Hong Van Beach, with calm, shallow water that’s genuinely good for easy swimming; the even quieter Bac Van a bit further along the coast; and Tinh Yeu Beach, conveniently close to Co To Town for a quick visit between other plans. Renting a motorbike is the standard way to string these together in a single day, and the ride itself, along the island’s quiet coastal roads with the sea in view for long stretches, is enjoyable enough to count as its own activity rather than just transport between stops. Rental shops cluster around Co To Town, and prices are generally straightforward and non-negotiable; fill the tank before you set out, since there are far fewer fuel stops once you’re on the island’s quieter stretches of road. A full motorbike loop connecting Hong Van, Bac Van, and Tinh Yeu comfortably fills half a day, with plenty of good stopping points to swim or simply sit and look at the water along the way.

7. Eat fresh seafood in Co To Town after dark

Co To’s evening seafood scene in its small town center is one of the island’s simple pleasures: fresh catch, straightforward grilling or steaming, and prices that reflect how close you are to where the fish actually came in rather than any resort-style markup. It’s also the easiest way to end a day of beach-hopping or hiking without needing to plan much — just wander the town’s handful of restaurant strips and pick whatever looks busiest with locals as well as visitors. Three full days is enough to comfortably cover all seven highlights without rushing: one day for Van Chay Beach and the lighthouse, one for Cau My Cliffs and the Co To Con boat trip, and one for the motorbike loop to the quieter beaches, the historical sites, and an evening of seafood. Two days works if you’re willing to combine the cliffs and the boat trip into a single busier day, though you’ll feel the pace more.
