Do not book a Lan Ha Bay tour for Monkey Island without checking what “visit” means on your travel date. Monkey Island, or Cat Dua, still appears in Cat Ba’s published tourism-route framework, but late-2026 visitor information is inconsistent: some operators still advertise a landing, while other current local guidance says direct landing is restricted and recommends confirming access first.
For Vietnam Story, that makes this an access-status and route-fit decision, not a promise of a beach stop, monkey encounter, viewpoint hike or kayak session.
Can you still visit Monkey Island in 2026?
Possibly, but direct landing should be confirmed with the actual operator. Hai Phong’s published Cat Ba tourism-route framework includes Đảo Khỉ on day Routes 1 and 2 from Ben Beo. That tells us the island remains part of the recognised route geography.
It does not prove that every boat can land there on every date. Current local travel information in October 2026 reports restricted direct landing for at least some operators, while another active operator still lists a Monkey Island landing in its itinerary.
Before choosing a tour for this stop, ask one precise question:
“Does Monkey Island mean a permitted landing, a boat-side view, or a substituted stop on my travel date?”
If the answer is vague, choose the tour for the overall Lan Ha Bay itinerary rather than for Monkey Island alone.
What is Monkey Island, or Cat Dua?
Monkey Island is a small limestone island in the Lan Ha Bay side of the Cat Ba Archipelago. Its older local name is Cat Dua, associated with the wild pineapple plants found there.
Local historical material explains that monkeys were later brought to live on the island, which is how the popular name “Monkey Island” developed. We would not describe this as a wildlife-reintroduction project or a natural primate sanctuary.
The island is useful in travel planning because it sits close to the Cat Ba tourism circuit and has historically combined a beach stop, macaques and a rough limestone viewpoint. Whether all of those experiences are available now is a separate question.
What monkeys live on Monkey Island?
The monkeys associated with Cat Dua are macaques. Do not confuse them with the Cat Ba langur.
The Cat Ba langur is a critically endangered endemic primate of the archipelago. UNESCO describes the World Heritage property as maintaining only a small population and notes that tourism disturbance remains a conservation concern.
Monkey Island is not a Cat Ba langur-viewing stop. Do not select this tour expecting to see the endangered langur.
How should you behave around the macaques?
If a landing is permitted and macaques are present, keep the visit simple and low-interaction:
- Do not feed them. Feeding changes animal behaviour and can increase aggressive food-seeking.
- Do not touch or approach them for a photo.
- Keep snacks out of sight. Food should stay inside a closed bag.
- Secure loose items. Phones, sunglasses, hats and small bags can attract curious animals.
- Keep children close to an adult. Treat the macaques as wildlife, not as a petting attraction.
We would avoid old copy calling them “mischievous thieves” or encouraging playful interaction. The useful advice is simply to give wildlife space.
Can you still use the beach?
Cat Dua has historically been described with two beach areas, usually called Cat Dua 1 and Cat Dua 2. That geographic distinction can still help you understand older itineraries.
But we would not promise a swim stop until the operator confirms current landing permission and the day’s sea conditions. A tour that passes Monkey Island does not automatically include beach access.
If swimming is the main reason you are choosing a Lan Ha Bay day trip, compare the full programme instead. Other operating beach stops can make a better decision point than an uncertain Monkey Island landing.
Can you still hike the Monkey Island viewpoint?
Only plan the viewpoint if direct landing and trail access are confirmed. Older itineraries describe a short but rough limestone scramble above the beach, with uneven and sharp rock underfoot.
We would not retain fixed claims such as a 15–20 minute climb, a guaranteed 360-degree view, “the best sunset point”, or a rule to avoid the trail for exactly two hours after rain. Conditions vary, and the more important question is whether the landing and path are open at all.
For travellers who specifically want a reliable island viewpoint in the Ha Long route system, compare this with Ti Top Island, where the viewpoint is an established part of official Ha Long Route 2.
Can you kayak or snorkel at Monkey Island?
Do not assume either activity is included. Old Monkey Island guides often publish kayak-rental prices, fixed snorkeling seasons and coral-visibility claims. Those details are too dependent on current operating permission, activity zoning, sea conditions and the actual tour programme to treat as permanent facts.
For kayaking in particular, Cat Ba and Lan Ha water activities have been subject to tighter operating controls, so the selected operator should confirm what is legally operating on your date and where the activity actually takes place.
For the broader activity picture, use our things to do in Lan Ha Bay guide rather than choosing a tour from an old Monkey Island kayak price.
Monkey Island vs Ti Top: which fits your route?
| Decision factor | Monkey Island / Cat Dua | Ti Top Island |
|---|---|---|
| Bay area | Lan Ha / Cat Ba side | Ha Long Bay |
| Current landing | Confirm with operator | Established Route 2 stop |
| Viewpoint | Only if landing and path are open | Established viewpoint climb |
| Wildlife | Macaques may be present | Not a wildlife stop |
| Best reason to choose | Fits your Cat Ba/Lan Ha route | Fits classic Ha Long Route 2 |
The comparison is not about which island is “better”. It is about which one belongs naturally in the route you are already taking.
Is Monkey Island worth choosing a tour for?
Usually not as the only reason. We would choose a Lan Ha Bay tour for the complete route: cruising area, caves or lagoons, beach/swim stop, village or aquaculture stop, meal, boat quality and realistic activity permissions.
Monkey Island becomes a useful bonus if:
- the operator confirms a legal landing;
- you are comfortable around macaques;
- the beach or viewpoint is actually part of the current programme;
- it does not replace a stronger Lan Ha stop that better suits your group.
If landing is restricted, the tour can still be worthwhile if the rest of the Lan Ha Bay programme is good.
What should families and older travellers check?
For families, the main checks are wildlife behaviour, the step from the boat to any tender or shore, life jackets and whether the planned stop requires rough rock scrambling.
For older travellers or anyone with limited mobility, ask whether they can remain comfortably on the main vessel if the island visit involves an awkward landing or uneven path.
Hai Phong tightened water-tourism safety requirements in 2026, including strict life-jacket use for passengers on Cat Ba bay tours. We would follow the crew’s current safety instruction rather than treat a beach or small-boat transfer as automatically easy.
What old Monkey Island advice should you ignore?
We would remove or re-check:
- “primate paradise”, “premier wildlife hub” or “untamed sanctuary” positioning;
- a fixed count of more than 20 monkeys;
- claims that the macaques were reintroduced as a conservation project;
- guaranteed beach landing;
- guaranteed 15–20 minute summit hike;
- “best sunset viewpoint” claims;
- fixed kayak-rental prices;
- 150 coral species around the island;
- 8–25 metre water-visibility claims;
- May–October as a guaranteed snorkeling season;
- “very safe” swimming for families regardless of conditions;
- private 16:30 golden-hour access promises;
- Cat Ba langur sightings as part of the stop.
How Vietnam Story would check the itinerary
We would first ask the operator whether Monkey Island currently means landing, viewing from the boat or a substituted stop. Then we would check the rest of the route, any permitted water activity, the mobility level of your group and whether the stop adds enough value to justify choosing that vessel.
If the island is not accessible, we would rather choose a stronger Lan Ha programme than sell you an old itinerary that no longer operates as written.
For Indian families or groups, meal requirements should also be confirmed with the actual boat. Vegetarian or Jain requests can often be discussed in advance, but they should not be treated as automatic inclusions on a generic day cruise.
If you want Vietnam Story to check the current operator, Monkey Island access, substitute stops and route fit before building the northern Vietnam itinerary, browse our Vietnam tour packages. We can fit the Lan Ha Bay day into the wider route instead of choosing a cruise from an outdated Monkey Island promise.
