Vân Long Nature Reserve

Vân Long Nature Reserve, nicknamed 'the waveless bay,' is Vietnam's largest inland wetland - a flooded valley of karst peaks, submerged rice fields, and clear shallow water navigated by rowing boat, home to Vietnam's largest population of the critically endangered Delacour's langur.

Overview

Best Time to Visit
Oct – Apr is the core dry-season window for wildlife viewing (migratory birds and the best chance of spotting the langurs) and generally the most pleasant weather; May-June is a separate bonus window when lotus flowers bloom across parts of the wetland, adding a pink-and-green landscape though outside the main wildlife season. Jul-Aug tends to be rainy and less ideal. Within a day, early morning (before 11 AM) or afternoon after 3-3:30 PM are both well-reviewed for cooler temperatures, better light, and more active wildlife - avoid the midday heat
Entry Fee
150,000 VND/person for one round-trip boat route (20,000 VND entrance + 130,000 VND boat fee), per the official HTX Vân Long price list effective 10 Feb 2026 - notably cheaper than Tam Cốc's roughly 250,000 VND. Boats typically pair 2 people together. Children under 1m are typically free. Tipping the rower (commonly around 50,000 VND if you're happy with the trip) is customary, though it should remain voluntary even if a rower hints for more
Opening Hours
Roughly 6:00 AM – 5:30/6:00 PM, with slightly shorter winter hours in some years - check current times locally
Address
Gia Vân, Gia Viễn, Ninh Bình

Things to Know

Crowds
Very few tourists, often alone on the boat or seeing only a handful of other visitors
Accessibility
Boat rides are required to access the reserve; there's no walking or motorbike route through the wetland itself. Boat seating is wooden planks with no shade cover, so full sun exposure is a real factor
Seasonal
Langur sightings are generally considered more likely in milder, warmer dry-season conditions; lotus flowers bloom around May-June; colder snaps reportedly send the langurs into more sheltered spots, lowering sighting odds

About This Place

What Makes Vân Long Nature Reserve Special

Vân Long Nature Reserve, nicknamed 'vịnh không sóng' ('the waveless bay') for its still, glass-like water, is Vietnam's largest inland wetland protected area - 2,736 hectares of flooded karst valley in Gia Viễn District, 20km northwest of Ninh Bình city, established in 1998. The reserve was created specifically to protect the Delacour's langur (Trachypithecus delacouri), a black-and-white monkey endemic to northern Vietnam and one of the world's 25 most endangered primates - only a few hundred individuals survive in total, and Vân Long holds Vietnam's largest single population, with more than 40 recorded here. The reserve holds two official Vietnam records: for the largest natural landscape painting-like scenery of its kind, and for having the country's largest number of Delacour's langur individuals. The landscape is a submerged valley of karst peaks - including the named formations Núi Mèo Cào, Núi Mâm Xôi, and Núi Hòm Sách - rising from shallow clear water, navigated by wooden rowing boats through channels between the limestone formations. There are actually two distinct boat routes: one passes through a cave system (the reserve is sometimes described as having around 1,000 caves in total, though only a portion are part of the tourist route), while the other stays entirely on open water and reportedly offers better odds of spotting the langurs. A useful tip: ask your rower directly about combining both routes into one trip, since this isn't always offered upfront. Vân Long also served as one of the filming locations for the 2017 Hollywood blockbuster 'Kong: Skull Island.' The combination of endemic wildlife, intact wetland ecosystem, and boat navigation through karst makes Vân Long one of the most complete nature experiences in Ninh Bình - and one of the least crowded, receiving a fraction of the visitors that Tràng An draws.

How to Get There

Getting There

Vân Long Nature Reserve is 20km northwest of Ninh Bình city in Gia Viễn District. By motorbike from Ninh Bình, the journey takes about 35–40 minutes on flat provincial roads. The boat dock and ticket office are at the reserve entrance in Gia Vân village. Most accommodation in Ninh Bình can arrange transport to Vân Long. There is no public bus directly to the reserve - motorbike or private transport is the standard approach.

What to Expect

On the Ground

The boat tour takes roughly 1-2 hours, navigated by a local rower through wetland channels between the karst peaks. The water is shallow and clear - the limestone bottom visible in many sections. It's worth asking your rower directly about combining both available routes (one through a cave section, one entirely open-water) into a single trip, rather than assuming you'll get both automatically. The langur population inhabits the cliff faces of several specific karst peaks in the reserve, and the open-water route is generally considered to have better odds of a sighting than the cave route, though sightings are genuinely variable rather than guaranteed - some visitors see several individuals, others see none, depending on season, weather, and simple luck. If you do explore any deeper cave sections, don't go in without a guide, and travelling in a small group of 3-4 is a sensible precaution. The landscape is wide and open - different from the enclosed cave-and-river experience of Tràng An, with broad views over the flooded valley and mountain reflections in the still water. Waterbirds including herons, kingfishers, and cormorants are common throughout, and lotus flowers bloom across parts of the wetland around May-June.

Travel Tips

Tips

Vân Long is one of the best wildlife experiences in Ninh Bình and one of the better ones in northern Vietnam, though it's worth being honest that a langur sighting isn't a sure thing - visitor reports suggest something closer to a coin flip than a guarantee, even with good timing. The Delacour's langur is a genuinely rare animal regardless - there are more giant pandas in the world than Delacour's langurs - and seeing them in the wild at Vân Long, even briefly, is a privilege that few travellers to Vietnam take advantage of. Early morning gives the best odds, but go in with realistic expectations rather than assuming a sighting is guaranteed. Pair with Hoa Lư Ancient Capital in the afternoon - both are in the western part of Ninh Bình province and the combination covers the province's best wildlife and best history in a single day. If you're deciding between Vân Long and Tam Cốc and can only fit one boat tour into a tight schedule, Tam Cốc's rice-field scenery is the more iconic, classically photogenic choice for a first-timer; Vân Long suits travellers who prefer a quieter, more genuinely wild setting, care more about wildlife photography, or have already done Tam Cốc and want something different. Worth noting: as of 2026, there are reportedly plans for a large (2,100+ billion VND) project to build a new pier and restore part of the old river system at Vân Long, which could bring more developed sightseeing infrastructure and improved conservation in the coming years - worth checking current status if you're curious how the site might have changed by the time you visit.

Insider Tips

Based on real traveler experiences and commonly mentioned advice from multiple visitors.

Bring a hat, sunscreen, and water for extended sun exposure on open water with no shade
Late afternoon can also be rewarding for sunset light and birds returning to roost, as an alternative to the classic early-morning langur-focused visit
Bring binoculars for better wildlife viewing; tipping the boatman is customary and appreciated
Go at 6–7 AM for the best langur sighting odds - the monkeys tend to descend to the cliff base to feed in the early morning, though sightings are genuinely not guaranteed and depend on weather and season
Request a quiet rower rather than an electric boat - the langurs are sensitive to engine noise and the rowing boats allow much closer approach
Bring binoculars - the langurs are on the cliff faces, sometimes 100+ metres away, and are hard to appreciate without magnification
Vân Long is significantly less visited than Tràng An and Tam Cốc - visit it first on a Ninh Bình trip before the crowds arrive at the more popular sites
The water level is lowest in February–March, exposing more of the karst rock and making the landscape more dramatic - but any dry season month is excellent
Cold weather reportedly drives the langurs to shelter more, so a cold snap can lower your odds of a sighting even in the right season - if wildlife viewing is your priority, milder dry-season days are better bets than a cold spell
Tipping the rower is customary and appreciated at the end of the tour

FAQ

Common questions from travelers who've visited this place.

How much does a boat tour cost?›
150,000 VND per person for one round-trip route (20,000 VND entrance plus 130,000 VND boat fee), per the official 2026 price list. Tipping the rower on top of this is customary.
How long is the boat ride, and does it go through caves?›
The standard boat tour lasts about 1-2 hours. Vân Long has two main routes - one includes a cave section, the other stays entirely on open water and is generally considered better for spotting langurs. Ask your rower about combining both if you want the full experience.
Will I see monkeys and other wildlife?›
Sightings are not guaranteed. Delacour's langurs and various bird species are present, but visibility depends on season, weather, and luck - some visitors report something closer to a 50/50 success rate even with good timing. Early morning in mild dry-season weather gives the best odds.
