Ba Be National Park guide: the lake, Puong Cave and Tay homestays

What Ba Be is, and why you sleep by the lake

Ba Be National Park was created in 1992 and covers 10,048 hectares, according to Vietnam's Nature and Biodiversity Conservation Agency. It was named an ASEAN Heritage Park in 2004 and a Ramsar wetland in 2011, the 1,938th in the world and Vietnam's third. At its centre is the lake: up to about eight kilometres long, 17 to 23 metres deep on average and about 35 metres at its deepest, with a surface that rises and falls between roughly 300 and 500 hectares with the seasons. The agency counts 1,268 species of higher plants, 182 of them orchids, and 470 vertebrate species in the park.

Since the 2025 provincial merger, the lake lies in Ba Be commune in Thai Nguyen province; older maps, signs and booking pages still say Bac Kan province, Ba Be district or Nam Mau commune, so search under both names. The lake area is not a town. Lodging is mostly family homestays in the Tay villages on the shore, and the commune names Pac Ngoi, Bo Lu, Coc Toc and Ban Cam as its homestay villages.

That is the reason to stay rather than visit. A homestay owner quoted by the provincial newspaper in 2026 noted that most visitors stay only one or two days, and a single night leaves you with a rushed boat trip squeezed between two long drives. With two nights, the lake gets a full day and the villages get an evening and a morning.

The boat day: An Ma, Puong Cave, Dau Dang and Ao Tien

Almost everything worth seeing on the water fits into one boat day, and the boat is how you get between the sights. The commune describes the classic loop: An Ma Temple on its island in the lake, Ao Tien (the Fairy Pond) on the northern side, Puong Cave on the Nang River and Dau Dang Waterfall beyond it, with Ba Goa Island, the Widow's Island, in the Pe Leng basin. The provincial tourism portal describes another way in: motorboats from Buoc Lom pier run down the Nang River and through Puong Cave into the lake.

An Ma Temple stands on a limestone island about 30 metres high; the provincial tourism portal says the old temple was restored in 2006. Local tradition holds that it honours loyalists of the Mac dynasty who died at Puong Cave in the wars of the late 16th and early 17th centuries. Puong Cave is a tunnel cut by the Nang River: the commune gives a ceiling of more than 20 metres, an average width of 30 metres and a river passage of almost 300 metres, home to 23 species of bats. Dau Dang is where the Nang breaks over a jumble of boulders in three tiers along a steep stretch of about 500 metres, with a wooden walkway for visitors. Ao Tien is a small pond enclosed by cliffs and forest, about 100 metres on foot from the lake shore.

Boats are run under the tourism area's management, and the price list is posted at the piers; that list, not a quote from a stranger, is what counts. A 2024 report by the Vietnam News Agency's Bao Tin Tuc cited a 2023 notice setting 300,000 dong for Route 1, from the pier on the north shore to An Ma Temple and back. We could not find a current official price list online, so check the board at the pier and agree the route and the stops before you set off. Take water, a hat and a layer for the cave, and expect the longer routes that include Dau Dang to take most of the day.

Hua Ma Cave and the land side of the park

Hua Ma Cave is the dry cave of the area, and the provincial tourism portal calls it the most intact natural cave in the area. It lies about eight kilometres from the centre of the park, halfway up a mountain in Ban Pjan village of Dong Phuc commune (formerly Quang Khe commune). From the foot of the mountain, a stone stairway of more than 300 metres climbs to the entrance; you then descend about 100 metres into a chamber nearly 700 metres long, with a ceiling up to 50 metres high and a dry floor. Wear shoes with grip and allow time for the climb.

On land, Vietnam's national tourism site points to hiking trails that fan out around the lake and to the quiet roads along the water, which suit a bicycle. Homestays and local guides can arrange both. The provincial broadcaster reports SUP boards, kayaks and lakeside camping on offer, and the national tourism site notes that the calm water is used for swimming and fishing; ask your host where it is sensible to swim.

Keep the day after the boat trip for one of these rather than a second round of sights. A morning climb to Hua Ma and an afternoon in a kayak, or a walk between Pac Ngoi and the neighbouring villages, is a better use of Ba Be than covering more distance.

Staying with a Tay family

The Tay are Vietnam's second-largest ethnic group, and the national tourism site describes how they settle in valleys beside rivers and lakes, in raised wooden houses, with wet-rice farming and fishing as part of daily life. At Ba Be you can stay in such a house and, as the national tourism site puts it, learn fishing and boating first-hand from your host family. The commune lists fishing, brocade weaving and cake-making among the traditional activities visitors can join, and evenings of Then singing to the tinh lute, the Tay's long-necked instrument.

Pac Ngoi is the best-known village, on the lake shore, and the obvious choice for a first visit. Bo Lu is where the Long Tong spring festival is held. Coc Toc and Ban Cam are smaller. Before you book, check whether you are getting a private room or a space on a shared sleeping floor, what bathroom you will share and whether dinner with the family is included.

This is a lived-in village, not a show. Follow your hosts' lead on shoes inside the house, ask before photographing people, and keep music and voices down in the evening. Book ahead for weekends and Vietnamese holidays, when domestic visitors fill the lake.

Getting there from Hanoi, and onward to Cao Bang or Ha Giang

Ba Be has no airport or railway. Vietnam's national tourism site puts the trip at about six hours from Hanoi, and suggests booking through a tour company or arranging it yourself; it names Mr Linh's Homestay as one host that arranges transfers from the capital. A new 37-kilometre road from Bac Kan to the lake, opened in April 2025, has cut that last leg from more than two hours to under one, according to the former Bac Kan provincial newspaper, so current journey times may be shorter than older guides suggest. The commune puts the lake about 50 kilometres from Bac Kan ward.

We found no official timetable for buses from Hanoi to the lake, so we do not give one. In practice, most international visitors come on a tour, by private car or by a transfer arranged through their homestay. If you take a bus, confirm with your host where it stops and how you will cover the last stretch to the village.

The same new road continues west towards Na Hang in Tuyen Quang province, and Cao Bang lies further north. That is what makes Ba Be useful on a northern loop: a gentle lake stop between Hanoi and the more demanding roads of Ha Giang or the Cao Bang border country. Treat each move between them as a travel day.

When to go: rain, cold and festivals

The national tourism site describes the forest as green all year, with dry, chilly winters and occasional storms between July and October that can disrupt travel plans. Pack a warm layer for winter nights in a wooden house, and in the rainy months build a spare half-day into the plan in case a boat trip is cut short.

Two dates stand out. The Long Tong spring festival at Bo Lu, on the 10th day of the first lunar month, brings tug-of-war, stick-pushing, bull fights and dugout canoe races, according to the commune; the An Ma Temple festival follows on the 6th day of the second lunar month. In March and April, after the first heavy rains, the commune describes shoals of fish leaping the rapids at Dau Dang. Festival days and national holidays are the busiest; ordinary weekdays are the quietest.

A workable two-night plan

This is an editorial suggestion, not a timetable. Check the weather and the boat routes with your host the evening before.

• Day 1 — Arrive: leave Hanoi early, reach the lake by the afternoon, settle into a homestay at Pac Ngoi or Bo Lu and walk the shore before dinner.
• Day 2 — Boat day: a full day on the water to An Ma Temple, Ao Tien, Puong Cave and Dau Dang Waterfall, with lunch arranged through your host or the boat driver.
• Day 3 — Land and leave: climb to Hua Ma Cave or kayak in the morning, then drive back to Hanoi or on towards Cao Bang or Ha Giang.
• Only one night? Do the boat loop on the first full day and skip Hua Ma; expect most of both days to go on the road.
