Van Long Nature Reserve: a quieter boat ride and langurs

The short answer

Van Long Nature Reserve is a Ramsar-listed wetland in Ninh Binh, where limestone karst rises from marsh and a freshwater lake. Fauna & Flora says it holds the largest population of the critically endangered Delacour's langur, and the boat goes through the wetland and grottoes where visitors can look for it. The national tourism site says lesser-known boat options like this one are not as busy as the Tam Coc and Trang An tours. A sighting is possible. It is never guaranteed, and we found no official source that gives odds.

Van Long paused in the September 2026 floods and has since reopened. Weather can still close the boats, so check on the day.

We are based on Cat Ba. We do not run Ninh Binh day tours, so this is not a trip report. It is built from official and conservation sources that we checked against each other.

We leave out ticket prices, opening hours and ride times on purpose. The sources we trust disagree on some of them, and the rest change. Ask at the pier or check close to your dates.

Is Van Long quieter than Tam Coc and Trang An?

The national tourism site says lesser-known boat options such as Van Long are not as busy as the Tam Coc and Trang An tours. That is all we can source, so we make no other claim about queues or crowds.

For contrast, the Tam Coc ride is the shorter one. It runs along the Ngo Dong river and typically stops at the three caves the name refers to. If you want to compare the two big piers first, read our guide to the Tam Coc and Trang An boats.

What Van Long Nature Reserve actually is

Van Long became a Ramsar site on 10 February 2017, and Ramsar calls it one of the few intact lowland inland wetlands left in the Red River Delta. The setting is limestone outcrops rising abruptly from a flat plain, with a freshwater lake, marshes and underground water around them. Ramsar says that combination is very rare in the Indochinese Peninsula.

The reserve was established in 2001 and is on the IUCN Green List of Protected Areas. It is one of several inland boat sites in Ninh Binh, alongside Trang An, Tam Coc and Thung Nham.

Delacour's langur, and why this wetland matters

The IUCN Red List classes Delacour's langur as Critically Endangered. That assessment dates from 2015 and is marked as needing an update. Fauna & Flora says the species survives at only five sites in northern Vietnam, and that its largest population, a few hundred animals, is in Van Long. Ramsar goes further and says more than half of the global population lives in the reserve.

A second population lives at Kim Bang, also in Ninh Binh province. We found no source saying it is a place to visit.

If you scan the rock faces, this is what you are looking for.

• Black above, with white from just above the hips to just above the knees.
• White cheek whiskers and a long bushy tail.
• Family groups on the karst slopes, eating mainly leaves.

Will you see the langurs?

Honestly, we cannot tell you. We found no official or conservation source that gives a chance of seeing langurs from the boat. They are wild animals on limestone cliffs, and visitor accounts of seeing them are individual stories.

Tour and visitor sources mostly name early morning or late afternoon as the better times, and they give different hours for each. None of it is an official wildlife-viewing schedule, so we give no clock times.

The tourism site also lists chamois, Chinese pond heron and stump-tailed macaque among what to look for, and Ramsar says waterbirds stage here. Bring binoculars, scan slowly, and let the ride be worth it even if the cliffs stay empty.

How the boat trip works, and what we could not confirm

What we can source is short. The ride goes through the wetland and grottoes, and the reserve has Dich Long Pagoda. Figures for the rest circulate online, but they disagree or change, so we leave them out. Ask at the pier, or check close to your dates, for these:

• The ticket price.
• The opening hours.
• How long the ride lasts.
• How many people share a boat.
• How the boat is rowed.
• How far it is from Tam Coc or Trang An.

Check it is open before you go

Van Long suspended operations on 17 September 2026 in the floods and has since reopened. Floods and storms can pause it again, so check it is operating before you set off. The tourism department advises checking with the site, a travel agency or your accommodation before departure, and activities are to resume gradually after water levels recede and affected sites are inspected and deemed safe. In heavy rain, status and routes can change during the day. We found no published rain amount at which Ninh Binh boats stop. Our guide to Ninh Binh in the rain covers the wider picture.

Visiting quietly

The IUCN lists recreational activities among the threats to the langur, alongside mining and quarrying and hunting. We read that as a reason for care, not a claim about any one boat. Keep your voice low, do not call out or shine lights at the cliffs, and keep your distance.

Fauna & Flora names cement mining, illegal logging, deforestation and hunting as the threats to the habitat, and says ecotourism may be considered to fund forest protection. We found no source saying a Van Long ticket pays for conservation, so we do not say it does. The langurs are guarded by the Ninh Binh forest protection department together with community rangers, some of them former poachers.

Van Long, Tam Coc or Trang An: which one for you

If the cave ride is the point, pick Tam Coc or Trang An. If you travel slowly, our guide to a slower pace in northern Vietnam shows how we plan the gentle days. If you are deciding between one day and two, our guide to how many days in Ninh Binh helps.

Fitting Van Long into a northern trip

We run no Ninh Binh day tours. Our tailor-made Northern Vietnam, Slowly trip lasts 5 to 10 days and includes a full day in Ninh Binh at your own pace. We send a proposal and a price after we know your dates. Ask us what fits that day; we cannot promise Van Long is included.

Our Ninh Binh to Cat Ba transfer picks up at your hotel in Ninh Binh city, Tam Coc or Trang An, and takes four to five hours with the ferry. Lan Ha Bay cruises run 2 days 1 night from Tuan Chau: Tulip Cruise from $155 and Celina of the Sea from $165 per guest, sharing a cabin. Message us on WhatsApp at +84 961 737 103.

What we read for this guide

We read the official wetland and red list records, a wildlife conservation charity, a primate rescue centre, the national tourism site, and press reports of the provincial tourism department. Rules, fees and prices change quickly, so check close to your dates.
