CAT BA :2D1N Lan Ha bay-Ha Long bay with Plankton Excursion

The night kayaking is the star here. Paddle across dark water and stir the sea with your hands to see bioluminescent plankton sparkle around you. By day, you move through quiet limestone islands, hidden lagoons, and calm swimming spots instead of spending all your time in the busiest parts of Ha Long Bay.

I like the mix of activities, especially the cycle into Viet Hai Village and the chance to swim from the boat at Cam Lagoon. I also like the food record: Vietnamese meals include seafood and vegetarian choices, and several visitors singled out the cooking as excellent. The main caution is the overnight setup. Despite the name floating homestay, at least one departure used a boat cabin below deck rather than a room in a floating village, and the second day can be shortened by weather.

• Night kayaking for glowing plankton: A rare, gentle activity that depends on darkness and suitable conditions.
• Cam Lagoon swimming stop: A quiet place for a half-hour swim, with the option to jump from the deck.
• Viet Hai Village by bicycle: Rice fields, local life, seasonal farm work, and a fish massage.
• Two bay areas in one trip: See Lan Ha Bay and the southern side of Ha Long Bay with fewer crowds.
• Food is part of the appeal: Expect traditional Vietnamese meals, seafood, and vegetarian dishes.
• Friendly English-speaking guides: Guides named B, Chilly, and Moka have been praised for care, energy, and cultural explanations.

A quieter route through Lan Ha Bay

This 2-day, 1-night trip costs $110 per person and begins in Cat Ba Town. It is designed for people who want more than a standard scenic cruise. You spend time on the water, but also cycle through a village, swim in a private area, kayak through caves, and spend the night trying to spot plankton that glows under your paddle.

The setting is the southern part of Ha Long Bay and Lan Ha Bay, where limestone islands rise from calm water in all directions. The tour aims for a smaller, quieter feel rather than a loud boat party. That matters in this region, where a scenic bay can feel less peaceful once too many boats gather in the same place.

The price covers hotel pickup and drop-off in Cat Ba Town, all meals, bottled water, kayaking, squid fishing, and the plankton activity. You pay extra for drinks and the entrance ticket, listed as $16, or 400,000 Vietnamese dong. At this price, the trip offers good value if you want several activities and meals included, but remember that drinks and the entrance fee raise the final cost.

7:30 AM from Cat Ba Town to the fishing village

Pickup begins at 7:30 AM from Cat Ba Smile Tours at 204, 1/4 Street, or from your hotel in Cat Ba Town. The office transfers you roughly 1 kilometer to Beo Harbour, so the first morning is simple, but you should be ready early.

The boat first passes through a floating fishing village, described as one of Vietnam’s oldest. Your guide explains how fishermen and their families live and work on the water. This gives the scenery a human side. You are not just looking at karst islands, you are seeing a working coastal community.

The bay soon fills with memorable limestone shapes, including Turtle Islet, Toad Islet, and Candle Islet. The names help you notice the forms instead of watching a succession of similar rocks slide by. An English-speaking guide such as B, Chilly, or Moka may also add local information about Cat Ba, the bays, Vietnamese customs, and daily life.

Kayaking through Bright, Dark, and Bat Caves

The morning includes about one and a half hours of kayaking near the border of Lan Ha Bay and Ha Long Bay. The route includes Bright Cave, Dark Cave, and Bat Cave, with access to quiet lagoons hidden among the limestone.

This is one of the strongest parts of the trip for active sightseers. A kayak lets you move at your own pace and get closer to the rock walls than you can from the main boat. The caves and lagoons are also a welcome change from simply sitting on deck and taking photographs.

The outing does require some effort. You should bring swimwear, sunscreen, and a willingness to paddle for a sustained period. The supplied details do not specify kayak type, exact group size, or whether each person has a single or shared boat, so ask Cat Ba Smile Tours if that matters to you.

Swimming at Cam Lagoon

After kayaking, the boat heads to Cam Lagoon, a private swimming area in the middle of Ha Long Bay. You get about 30 minutes in the water, with time to swim or jump from the boat deck.

This stop works well because it breaks up the morning. After paddling through caves, you can cool off, float, and enjoy the bay without rushing from one attraction to the next. The water is described as clear and blue, though conditions can change with weather and sea conditions.

Bring a dry change of clothes and keep your phone protected. You can take photographs from the boat, but this is one part of the day when a waterproof pouch is more useful than another scenic picture.

Lunch, deck time, and the ride to Viet Hai

Lunch is served on the boat from noon to 1 PM. Expect traditional Vietnamese dishes, including seafood and vegetarian choices. Food received unusually strong praise in the supplied feedback, with special approval from people who ate vegetarian meals, so this is not merely a basic stop between activities.

After lunch, you have about 90 minutes to rest on deck, nap, sunbathe, or take photographs. The boat returns by another route toward Viet Hai Harbour. This quiet stretch is valuable because the schedule does not force you into an activity every minute.

Still, a boat trip is shaped by weather. Wind, rain, or rough water may change the route or remove a stop. One departure could not enter Ha Long Bay because of poor conditions, although Lan Ha Bay remained available. Keep that possibility in mind if seeing both bays is your main reason for booking.

Cycling from Viet Hai Harbour to the village

From Viet Hai Harbour, you cycle across rice fields to Viet Hai Village. The ride adds a rural side to a trip that could otherwise be all sea and limestone.

In the village, you can walk around, meet local residents, and learn about their way of life. Seasonal farm work may be available if you want to take part. There is also a fish massage, an unusual and lighthearted activity that some people will find memorable and others may happily skip.

The village visit gives the day a better rhythm. You begin with caves and swimming, then slow down among fields and homes. The cycling is not presented as a difficult sports ride, but you should still be comfortable on a bicycle and ready for outdoor conditions.

Dinner and the glowing water after dark

Dinner is served from about 6 PM to 10 PM on the floating homestay. The meal is traditional Vietnamese food, with seafood and vegetarian options included during the trip.

After dinner, you can try squid fishing or kayak to see bioluminescent plankton. The plankton is the special moment. In darkness, movement in the water can create small points of light around your paddle or hands. The effect is delicate rather than a large light show, and it depends on dark skies, water conditions, and the availability of plankton that night.

The supplied information does not promise that the plankton will appear every time, so treat it as a genuine nature encounter, not a guaranteed performance. If conditions cooperate, it is the kind of simple event you remember more clearly than another viewpoint.

The overnight arrangement deserves careful attention before you pay. The tour calls this a floating homestay, but one departure found the sleeping room in the lower part of the boat rather than staying in a floating village. Bathroom arrangements may also feel basic. If private sleeping space or a particular type of homestay is important to you, confirm the cabin and shower setup in advance.

A calm second morning on the bay

The second day begins at 8 AM with breakfast, sunrise views, and fresh air on the water. The later start gives you a little breathing room after the evening activities, though the exact comfort of the morning depends on your cabin and the boat.

At 9 AM, the boat heads toward Ho Ba Ham, an area known for three concealed lagoons. Around 11 AM, you visit Dau Be Island and have time at a deserted beach, followed by kayaking to explore Ho Ba Ham.

On paper, this is an excellent second-day combination: a beach, a kayak route, and enclosed lagoons. In practice, the schedule can change. One departure received kayaking but did not visit Dau Be Island or enjoy the beach as planned. Weather and sea conditions are likely factors, but you should ask how flexible the second-day route is if these stops are especially important to you.

Lunch follows at noon, prepared in a local cooking style. At 1 PM, the boat returns toward Lan Ha Bay for more kayaking around limestone islands, swimming at quiet beaches, sunbathing, and time on deck.

You get a useful final afternoon rather than a rushed return after breakfast. The tradeoff is that the tour finishes in Cat Ba Town at about 3:30 PM, so the exact time of each final activity may shift with the route and conditions.

How the trip feels on board

The strongest mood is relaxed and social. The trip is aimed at a small group, and the supplied feedback repeatedly points to friendly staff, enthusiastic guides, and a pleasant group atmosphere. Guides B, Chilly, and Moka are each associated with warmth, cultural explanations, or quiet attentiveness.

That human element matters on a 2-day trip. A good guide keeps the transitions clear, helps with kayaking, explains the villages, and makes a shared boat feel comfortable. Chilly is described as energetic and eager to share Vietnamese culture, while Moka is noted for a gentle, discreet manner. B is praised for explaining the bays, Cat Ba, and local history while taking care of practical needs.

The boat is not presented as a luxury cruise. You should book it for access to quieter places and a full activity schedule, not for a polished resort cabin. Deck time, swimming, meals, and scenery are the main pleasures.

Is $110 a fair price?

For $110, you receive transportation within Cat Ba Town, one night, all meals, bottled water, kayaking, squid fishing, and the chance to see bioluminescent plankton. You also get cycling, village time, several swimming opportunities, and an English-speaking guide.

That is a solid package for someone who wants variety. Booking similar elements separately could be awkward, especially the route between harbours, caves, villages, and remote swimming places. The price also covers food, which reduces the small daily costs that can add up on a boat.

The value is less convincing if you want a guaranteed Ha Long Bay route, a comfortable private cabin, or a beach visit that cannot be changed. The $16 entrance fee and paid drinks are extra, and the accommodation description should be confirmed before booking. Think of this as an active, local-style bay trip with basic overnight comfort.

Who should book this trip

I would choose this tour if you want to:

• See Lan Ha Bay with less crowd pressure than the busiest Ha Long Bay routes
• Combine scenery with kayaking, swimming, cycling, and village life
• Try squid fishing and a nighttime plankton outing
• Eat Vietnamese food on the boat, including vegetarian options
• Spend time with a guide who explains local culture and daily life
• Travel in a smaller, quieter group rather than join a loud party cruise

I would think twice if you need a high-end cabin, guaranteed access to every listed stop, or a completely predictable schedule. The trip involves outdoor activity, changing conditions, and a basic overnight setup. It is also not suitable for people over 95 years old.

Book with swimwear, sunscreen, a dry change of clothes, and a waterproof phone case. Keep your email and phone number available for pickup details. You can reserve now and pay later, and cancellation is allowed up to 24 hours before departure for a full refund.

My recommendation for Cat Ba visitors

Book this trip if the glowing plankton, quiet water, and mix of sea and village life appeal to you more than a luxury cruise cabin. The night kayak, Cam Lagoon swim, Viet Hai cycle, and strong food program give the trip real variety.

Before booking, ask Cat Ba Smile Tours to confirm the sleeping arrangement, current second-day route, and whether the Ha Long Bay crossing is likely under the forecast. With those points clear, this is a good-value choice for an active 2-day escape from Cat Ba, especially if you prefer calm water and small-group company over a crowded cruise circuit.
