Cat Ba Island Beaches: Cat Co 1-3, Tung Thu, Lan Ha Bay and 2026 Prices

Cat Co 1, Cat Co 2, and Cat Co 3 are the main public beaches on Cat Ba. Tung Thu is the quieter, rockier alternative. Sort them by water calm, lifeguard cover, and crowd level, and the choice gets simple. Cat Co 1 and Cat Co 2 have calmer water and seasonal lifeguards, so they are better for weak swimmers and families. Cat Co 3 is also a main public beach, but lifeguard cover is not specified for it, so confirm conditions on the day. Tung Thu is rockier and quieter for travelers who want fewer people and do not mind unstable footing.

Rip currents can appear at Cat Co 1 and Cat Co 2 after storms, even when the surface looks flat. Storm and typhoon risk peaks August to October, so check forecasts before a beach day, a ferry, or a Lan Ha Bay trip. Jellyfish turn up in summer. Construction near Cat Co can affect access. Do not trust a 2023 or 2024 blog post for 2026 lifeguard coverage, water quality after heavy rain, or path closures. Ask at your hotel or a local operator the same morning.

Timing changes the crowd. May to June and September to October give the best beach weather. July to August is hot, crowded, and pricier, so Cat Co 1 and Cat Co 2 fill early. November to March is cool with fewer swim days. If you have 2 nights, pick one Cat Co beach and keep the other morning flexible. With 3 nights, add a Lan Ha Bay trip, but remember Lan Ha Bay has no lifeguards, heavy kayak and boat traffic, and deep water. Wear a life vest and stay near the boat.

For Tung Thu, bring shoes you can walk on rocks in. If you are a weak swimmer, stay where seasonal lifeguards can see you. Ask about rip currents before entering. If the sea looks flat but a storm passed recently, wait or choose a pool day instead.

Cat Ba takes two legs: a road transfer to the coast, then a short ferry. Hanoi to Hai Phong by bus or limo takes 2 to 2.5 hours. From Ben Binh pier, the ferry to Cat Ba town runs roughly 45 minutes. Budget extra time at the pier for tickets and boarding, and reach the island before dark if you can, since onward transport thins out in the evening. Booking a morning bus or limo lets you catch an afternoon ferry and still arrive with daylight to spare.

Some travelers skip Ben Binh and use the Tuan Chau or Ha Long ferry routes instead. That suits anyone already booked on a Ha Long Bay cruise, because the crossing starts closer to the water. Schedules and pier fees change, so treat any 2023 or 2024 timetable as a rough guide only. Book high-season ferries ahead, particularly in July and August, and confirm same-day departures before you leave your hotel. Do the same for the return leg; afternoon sailings from Cat Ba town fill first when the island is busy.

Storm and typhoon risk peaks from August to October, which overlaps the tail of the crowded season. Check forecasts before both the ferry and any Lan Ha Bay trip, and again on the morning you travel. If a storm is tracking toward Cat Ba, shifting your dates is easier than rearranging plans on the coast.

Carry cash. Piers, ferries, and family guesthouses on Cat Ba run largely on notes rather than cards, and ATMs on the island are limited, so draw dong in Hai Phong before boarding. Two nights is the minimum worth the crossing; three nights leaves room for a Lan Ha Bay trip once the ferry back is confirmed. Schedules, pier fees, and 2026 rules can change mid-season, so verify locally rather than trusting older guides.

Cat Ba has two best swim windows: May to June and September to October. Water is warm and the sea is mostly calm, and Cat Co 1 and Cat Co 2 have seasonal lifeguards. Lifeguard coverage can change year to year, so ask at the beach before you rely on it. September and October also fall inside the August to October storm and typhoon window, so check forecasts before booking ferries or Lan Ha Bay trips.

July and August are the hot, crowded months. Rooms and ferry tickets cost more, and high-season sailings sell out, so book ahead and confirm same-day departures. The trip from Hanoi to Hai Phong by bus or limo takes 2 to 2.5 hours, then the ferry from Ben Binh pier to Cat Ba town runs about 45 minutes. Plan 2 nights minimum, or 3 nights to include a Lan Ha Bay trip. In summer, jellyfish are possible, so ask at the beach before a long swim.

September and October give warm water with fewer crowds than midsummer. They are also a best window. The trade-off is storm risk: typhoon season peaks from August to October. If you book during this period, keep ferry and bay plans flexible and check the forecast the day before.

November to March is cool, with fewer swim days. Swimming is still possible on calm, sunny afternoons, but do not plan a beach trip around it. Accommodation ranges from dorm or hostel beds at 200,000 to 400,000 VND ($8 to $15) to resorts at 2,000,000 to 4,000,000+ VND ($80 to $160+). Guesthouses sit at 500,000 to 900,000 VND ($20 to $35), and midrange hotels run 900,000 to 1,500,000 VND ($35 to $60).

Lan Ha Bay has no lifeguards, so a swim there is a boat or kayak activity, not a beach swim. Cat Co 1 and Cat Co 2 have seasonal lifeguards; the bay does not. You enter the water from a vessel or a kayak, watched by your guide or by your own group alone, and that changes what you wear, how far you go, and which operator you book with.

The water is deep and the traffic is heavy. Tour boats, transfer boats, and kayak groups cross the same channels through the day, and a swimmer's head is hard to spot from a wheelhouse. Wear a life vest. Stay close to your boat where its crew can see you, and do not swim toward the islands: the distance is longer than it looks and the current runs. Jellyfish are possible in summer. Storm and typhoon risk peaks from August to October, and rip currents appear after storms, so check forecasts before ferries and bay trips.

Permit and tour rules for Lan Ha Bay vary by operator, so ask what is included before you pay. Confirm whether the price covers bay or entrance fees, a life vest, kayak use, a guide who stays with swimmers, and a swimming stop at all. Some itineraries drop the swim when conditions are rough, which is the right call and worth knowing in advance. How water quality holds after heavy rain is an open question, so check locally rather than relying on 2023 or 2024 price guides.

Give the bay trip room in your schedule. Two nights is the minimum on Cat Ba, and three nights makes a Lan Ha Bay day easier to fit. Cash is useful for operator fees, and ATMs on the island are limited.

Cat Ba accommodation in 2026 falls into four price bands, and the gap between them is wide. A dorm bed or hostel room runs 200,000 to 400,000 VND ($8 to $15) a night, while resorts start around 2,000,000 VND and can pass 4,000,000 VND ($80 to $160+) in high season. The band you choose decides how close you sleep to the sand and how much of your budget goes to the room.

Between those ends sit guesthouses at 500,000 to 900,000 VND ($20 to $35) and midrange hotels at 900,000 to 1,500,000 VND ($35 to $60). Most guesthouses and midrange hotels cluster in Cat Ba town, within walking distance of the ferry pier and the seafood restaurants along the waterfront. Resorts sit further out, usually with pools and shuttle access to Cat Co 1 and Cat Co 2.

Rates follow the season. July and August carry the highest prices, driven by domestic school holidays, and the best rooms sell out weeks ahead. May, June, September and October are calmer and cheaper, with the same rooms often booking at the bottom of their band. November to March brings fewer swim days and softer rates, though some properties cut staff or close outside the season. Confirm 2026 rates directly with the property, since schedules and pier fees can change.

Cash is the practical snag. ATMs on the island are limited, and many guesthouses and small restaurants take cash only. Withdraw in Hanoi or Hai Phong before boarding the ferry at Ben Binh pier, which takes about 45 minutes to Cat Ba town. Keep small notes for ferry tickets and meals on arrival day. Two nights is the minimum stay; three lets you add a Lan Ha Bay trip, and you will want cash for that too.

Lifeguard cover on Cat Ba is seasonal, and which beaches have it can change from one season to the next. Ask at the beach or at your hotel desk before you swim instead of trusting last year's reports. The calm surface at Cat Co 1 and Cat Co 2 can hide rip currents that form after storms, and water quality drops after heavy rain, when runoff reaches the bays. Skip swimming for a day or two after a storm clears. Lan Ha Bay has no lifeguards, heavy kayak and boat traffic, and deep water, so wear a life vest and stay near the boat. Jellyfish appear in summer.

Construction near Cat Co can change access and noise levels. Ask before booking a room nearby whether work is running and whether it has cut off any beach access or added noise. Tung Thu is quieter and rockier, so ask locally about conditions there rather than assuming a swimming beach. Lan Ha Bay permit and tour rules vary by operator, so confirm the current permit position and what a quoted trip includes with the company you book.

Room rates change often. Price guides published in 2023 and 2024 no longer reflect what hotels charge, so confirm rates when you book. Demand in July to August pushes prices up, and the August to October storm window can shift ferry times and pier fees. Book high-season ferries ahead, confirm same-day departures, and treat any quoted rate as provisional until the hotel confirms it in writing.

Check three places before you commit: your hotel desk for beach and water conditions, the ferry office for that day's timetable and fees, and the operator running your Lan Ha Bay trip for permits and inclusions. Two nights is the minimum most travelers need on Cat Ba; three nights lets you add a Lan Ha Bay trip.
