What to do in Cat Ba: 7 island experiences worth your time
If you love hiking, spend your morning in Kim Giao Forest and on Ngu Lam Peak. For something more relaxed, choose Hospital Cave, Cat Co Beach, and the waterfront. Viet Hai Village deserves a full day of its own.

The harbourfront offers a sunset without a boat ticket; the best view changes as the clouds move.
Late in the afternoon, small boats sit quietly beneath the limestone cliffs of Cat Ba, while people begin gathering along the waterfront for the evening breeze. Besides the beaches, the island has a wartime hospital built inside a mountain, a forest trail, a peak with views over the limestone hills, and a village reached by boat across the bay. Pick a few places that suit your time and energy instead of trying to see everything at once.
What to do in Cat Ba: 7 experiences worth trying
Walk Along the Cat Ba Waterfront and Watch the Sunset
The easiest thing to do in Cat Ba needs no booking. Head to the waterfront in front of Cat Ba Town, find a pleasant stretch of pavement, and take your time.
On one side are restaurants, hotels, and people chatting over drinks. On the other, fishing boats and small passenger vessels float against a backdrop of limestone cliffs. It isn’t a deserted seaside escape, but that’s part of its charm. You’re watching an island town go about its evening.
The walk suits people who have just arrived, are waiting to check into their accommodation, or simply don’t feel like arranging another ride.
You can stop for a cold drink, take a few photos of the boats, and find somewhere nearby for dinner. It’s also an easy option for families traveling with older relatives, since there’s no strenuous hiking involved.
For a Cat Ba sunset, the public waterfront is a good place to start. As the afternoon light softens, the water catches the changing colors of the sky, and lights begin appearing on boats as evening approaches.
Not every spot faces the setting sun directly, but from the promenade you can watch the harbor go from afternoon light to boat lamps.
Stick to public walking areas rather than stepping onto working docks or getting too close to the water’s edge for a photograph.
Hospital Cave: Explore a Wartime Hospital Hidden Inside a Mountain
Only have room for one historical attraction on Cat Ba Island? Make it Hospital Cave, known locally as Hang Quân Y.
From outside, it looks like an entrance cut into a limestone hillside. Step inside, though, and you’ll find concrete corridors, rooms with rectangular doorways, and staircases connecting different levels. It feels nothing like an ordinary natural cave.
During the war, a field hospital was built inside the mountain to treat wounded soldiers and provide protection from bombing. Its former treatment rooms and working spaces offer a glimpse into what life was like here during those years.
The cave has artificial lighting and feels noticeably cooler than the outdoors. However, some stairways are steep, and the floor can be damp. Shoes with good grip are a sensible choice, particularly if you’re bringing children.
Hospital Cave is roughly 8 km from central Cat Ba Town, along the main road through the island. You can reach it by taxi or motorbike and allow around 45-60 minutes for the visit.
Typical visiting hours are 8:00 AM-5:00 PM, although opening times may change. Tickets are sold at the cave entrance, with prices posted there, so check that board or ask your accommodation before visiting rather than relying on older prices online.
It’s a good choice for history enthusiasts, families with children comfortable using stairs, and travelers looking for something different to do around midday.
Walk Through Kim Giao Forest for a Different Side of Cat Ba
After spending time by the sea, entering Kim Giao Forest feels like arriving on another island altogether.
The trail winds beneath a green canopy, sometimes across dry leaves and earth, sometimes over stones and exposed tree roots. The busy sounds of town disappear, replaced by rustling leaves and the quieter atmosphere of the forest.
Kim Giao Forest is part of the central sightseeing route in Cat Ba National Park, which also includes Ngu Lam Peak and Trung Trang Cave.
The forest section works as a walk on its own, without the summit. For something gentler, follow part of the trail and turn back when you’re ready.
The first stretch looks easy, but fallen leaves can conceal loose stones, while damp rocks become slippery after rain. Proper walking shoes are much better than flip-flops.
Cat Ba National Park central route admission fees, effective January 1, 2026:
- Adults: 120,000 VND per person
- Children aged 6 and above: 60,000 VND per person
- Children under 6: Free under the general admission rules
These fees apply to the central sightseeing route covering Kim Giao Forest, Ngu Lam Peak, and Trung Trang Cave. They are not the admission fee for the entire national park, which is listed separately at 160,000 VND for adults.
Planning to combine the forest trail with Trung Trang Cave? Confirm exactly what your ticket covers at the counter before buying.
Hike Ngu Lam Peak for Views Across the Limestone Mountains
For travelers interested in hiking on Cat Ba Island without committing to a long jungle trek, Ngu Lam Peak is a good place to begin.
The trail starts fairly gently. As you climb, it becomes steeper, with stone steps and uneven sections where you slow down, stop in the shade and drink some water.
From the top, green limestone hills stretch into the distance, one ridge rising behind another.
Ngu Lam Peak reaches approximately 273 meters above sea level.
Tackle the climb in the morning, before the strongest heat arrives and while your legs still feel fresh. Bring enough drinking water, wear shoes with reliable grip, and leave yourself plenty of time for the descent.
A ticket doesn’t commit you to the summit. After rain, the rocks and soil can be slippery; if conditions are poor, switch to a lower forest walk or another attraction instead.
Ngu Lam is best for reasonably active travelers who enjoy walking and don’t mind steep sections. Anyone who struggles with stairs, has knee problems, or is very young will do better on a lower forest walk or the waterfront.
Trung Trang Cave: Walk Through a Limestone Mountain
Also located in the Cat Ba National Park area, Trung Trang Cave is worth considering if you enjoy natural caves.
Unlike Hospital Cave, where human-built corridors and rooms are the main attraction, Trung Trang is known for its limestone formations and natural passageways.
Artificial lights pick out the shapes and textures of the rock, creating changing patterns of light and shadow as you move through the cave.
Some sections are narrow, with low ceilings and relatively high steps. At certain points you duck under the rock, so watch the ceiling as well as your feet.
The cave is generally cooler than the outside air, making it a pleasant midday stop when conditions are suitable.
After a morning walking through Kim Giao Forest or climbing Ngu Lam Peak, Trung Trang can fit into the same outing, provided it’s open and you still have enough time and energy.
Travelers who feel uncomfortable in confined spaces, have difficulty bending, or struggle with irregular steps may find parts of the route challenging.
If it has been raining, ask the staff whether the cave is open and the walking route is safe. Never enter closed sections, even if the entrance appears accessible.
Spend an Afternoon at Cat Co Beach
The Cat Co beaches sit close to the main town, with soft sand and dramatic limestone cliffs rising behind them.
You can go for a swim, stroll along the shoreline, or find somewhere comfortable to sit and listen to the waves.
For photography, the rocky headlands surrounding the sand give Cat Ba’s beaches a different look from the long, open stretches of coastline found elsewhere in Vietnam.
Don’t assume that Cat Co 1, Cat Co 2, and Cat Co 3 are all accessible or connected by open walking paths. Beach operations and the cliffside paths between them may change.
Ask locally which beaches are currently open and which connecting paths are safe to use.
For swimming, choose a supervised beach with lifeguards, stay within the marked swimming area, and follow the day’s warning flags. Sea conditions matter more than getting to a particular beach you saw in a travel photo.
With only half a day in Cat Ba, an open Cat Co beach followed by a waterfront walk fills the afternoon.
Viet Hai Village: Slow Down Among Mountains and Gardens
To get away from the busiest part of Cat Ba for a full day, the place to go is Viet Hai Village.
Tucked into the Cat Ba National Park area, the village is surrounded by forests and mountains.
Narrow roads pass small houses, gardens, and stretches of greenery beneath the limestone hills. Life feels very different from the busy waterfront in town.
Walk slowly, look around the village, stop beside a garden, or spend time cycling along the quiet roads.
Can you drive a car from Cat Ba Town directly to Viet Hai Village?
No. There is currently no direct road suitable for cars connecting the town to the village.
The usual route is to head to Ben Beo Pier, about 2 km from central Cat Ba Town, and take a boat or speedboat across Lan Ha Bay to the Viet Hai landing area.
From there, you can continue toward the village by bicycle, electric vehicle, or on foot, depending on the transport services available.
Another option is a forest trek of approximately 12 km through the national park. This is better suited to experienced walkers and requires proper footwear, water, a guide, and a clear plan for getting back.
A scheduled half-day boat tour from Ben Beo can cover Viet Hai, leaving in the morning and getting back to the pier around midday, with time for a walk around the village.
Arranging boats yourself, cycling the village roads, or lingering in a garden calls for a full day, and a tight return boat leaves you watching the clock in the village.
Before leaving, confirm the return boat schedule, transport costs, and any applicable admission fees.
For boat journeys on the bay, passengers must wear life jackets throughout the trip, and boats may only depart when authorized.
Only have half a day in Cat Ba? A short plan
Keep a single morning or afternoon to two main activities at most.
Cat Ba has plenty to see, but the attractions aren’t all within walking distance of each other.
Option 1: History and an easy waterfront walk
Start with Hospital Cave. After exploring the former wartime hospital, return to Cat Ba Town for a drink or a short break.
Afternoon visitors can finish with a walk along the waterfront as the sunlight fades.
This works for couples, friends interested in history, and families whose members can manage the cave’s stairways, and it isn’t tiring.
Option 2: Beach time and a relaxed afternoon
Choose one of the Cat Co beaches that’s open to visitors. Go for a swim, sit on the sand, or enjoy the sea views.
Later, return to the town waterfront to watch the evening boats and find somewhere for dinner.
This option makes sense if you’ve just had a long journey and don’t feel like arranging more transport.
Half a day is still enough for Ngu Lam Peak in the morning, as long as you keep most of the time free for the climb and the return journey instead of trying to fit in several caves as well.
A full day in Cat Ba: forest in the morning, beach in the afternoon
With one complete day on the island, a good approach is to do the more physically demanding activities first, take a proper lunch break, and leave the sea for later.
In the morning, head to the central area of Cat Ba National Park.
If you’re reasonably fit and the trails are dry, walk through Kim Giao Forest and climb toward Ngu Lam Peak.
Those more interested in caves than climbing can choose Trung Trang Cave instead or combine the attractions according to the time available and current access conditions.
Around lunchtime, return to town for food and a rest.
After a hot morning on the forest trails, you will want that break.
In the afternoon, when the sunlight becomes softer, visit one of the open Cat Co beaches.
Swim or just walk on the sand and take a few photographs, then end the day on the town waterfront.
If Viet Hai Village is your main priority, though, give it the entire day instead.
Leave the Ngu Lam climb for another day unless you’re joining a properly organized trekking itinerary with a guide and a clear return plan.
What to do in Cat Ba when it rains
Light rain still leaves a few options, though a cave in wet weather has risks of its own.
If the rain is light, road conditions are good, and the attraction confirms it’s open, Hospital Cave may still be worth considering.
Its concrete corridors and naturally sheltered interior make it less dependent on sunshine than outdoor activities.
However, you’ll still need to take care on damp floors, staircases, and the approach to the entrance. Hospital Cave isn’t an emergency storm shelter, and visitor access is always subject to the site’s management.
Trung Trang Cave may also be possible to visit when conditions allow, but wet steps, narrow passages, and uneven surfaces can make the experience more difficult.
Skip it during prolonged heavy rain or when there are safety warnings.
Rainy days call for short travel distances.
You could enjoy a leisurely lunch in town, spend some time in a café, and take a short waterfront walk if the rain clears.
Heavy rain, strong gusts, or an official severe-weather warning: cancel mountain hikes and boat trips and avoid caves or trails where access has been restricted.
Better to skip a stop than push through unsafe conditions just to complete an itinerary.
Which Cat Ba activities suit your travel style?
Active travelers should prioritize Kim Giao Forest and Ngu Lam Peak. Start early, bring enough water, and climb at your own pace.
If you enjoy history, Hospital Cave will probably leave a stronger impression than another afternoon at the beach. Its corridors and rooms reveal a side of the island that can be easy to miss.
Visiting with young children? Consider a supervised Cat Co beach and the public waterfront. Caves may still be suitable for children who are confident on stairs, but adults should supervise them closely around slippery steps and uneven floors.
With older family members in tow, leave out the mountain climb and the caves with difficult steps. A seaside walk, drinks with a view of the boats, and dinner in town fill an easy day.
Prefer quiet places? Viet Hai Village is worth dedicating a separate day to. Take the boat from Ben Beo, or the forest trek for fit walkers, then walk the village slowly.
Is Cannon Fort in Cat Ba open again?
Cannon Fort, also known as Pháo đài Thần Công, used to be one of Cat Ba’s most frequently recommended sunset viewpoints.
Set on a hill above town, it became known for its sea views and former military structures.
However, there’s been no announcement that Cannon Fort has reopened to tourists.
The site remains closed or access is restricted, with some approach roads blocked.
For that reason, plan your visit without assuming you’ll be allowed inside.
Old online information about entrance fees, opening hours, and the hilltop café may no longer be valid.
Still keen to visit? Ask your accommodation or a local tourism operator for the latest status. Don’t cross barriers or attempt to enter through unofficial paths.
And if you’re mainly looking for sunset views, a pleasant public spot along Cat Ba’s waterfront is a much simpler and more dependable option.
A few things to remember before exploring the island
Start with footwear.
Flip-flops are fine for the beach, but bring a pair of shoes with good traction if you plan to visit caves or walk through the forest. Wet limestone, steep steps, and trails covered in leaves aren’t particularly friendly to slippery sandals.
Next, try not to overload your schedule.
Fewer places, with proper breaks for food and rest, make for an easier day than a list of famous stops.
Finally, check whether attractions are actually open on the day you plan to visit.
Beaches, cliffside paths, caves, and forest routes can temporarily close because of weather, maintenance, or management restrictions.
For boat journeys, follow the crew’s safety instructions, wear your life jacket from boarding until the journey ends, and only travel on vessels authorized to depart.
On Cat Ba the forest and the sea are close together: the morning beneath forest trees, the afternoon beside the water, and dinner when the town lights come on.

What can I do in Cat Ba if I only have half a day?
For a relaxed itinerary, visit Hospital Cave and then walk along the town waterfront. Alternatively, spend the afternoon at an open Cat Co beach and stay for the sunset atmosphere.
