What it is
Thac Ban Ba is a multi-tiered limestone waterfall tucked into dense forest in Lam Binh district, roughly 130 km northeast of Tuyen Quang city. The falls drop across three main levels — the highest cascade around 50 meters — into pools colored a milky blue-green by calcium carbonate deposits. The surrounding area is home to Tay and Dao ethnic communities who've farmed these valleys for generations.
The waterfall only started appearing on traveler radars around 2018-2019, when local authorities improved the access road and built a basic trail system. Before that, it was mostly known to villagers and the occasional motorbike tourer pushing through the backroads between Tuyen Quang and Ha Giang.
Why travelers go
Thac Ban Ba isn't on bus-tour itineraries. That's the point. You get a legitimate jungle waterfall without the crowds you'd find at Ban Gioc or Thac Bac near Sapa. The pools at the base are swimmable in the dry months, the surrounding forest is dense enough to feel remote, and the ethnic minority villages nearby offer homestay experiences that haven't been polished for mass tourism yet.
For motorbike travelers heading to or from Ha Giang (하장 / 河江 / ハーザン), Thac Ban Ba makes a worthwhile detour — it breaks up the long ride and gives you something beyond mountain passes and rice terraces.
Best time to visit
The sweet spot is September through November. The rainy season (June-August) pumps up the water volume and makes the falls dramatic, but trails get slippery and leeches come out in force. By September the flow is still strong but paths dry out. December through February is cooler and drier — comfortable hiking weather, though the falls thin out considerably.
Avoid Tet and major Vietnamese holidays if you want solitude. The waterfall has become a regional day-trip destination for families from Tuyen Quang city, and holiday weekends bring minivans.
How to get there
From Hanoi: Take a bus from My Dinh station to Tuyen Quang city (roughly 3 hours, 120,000-150,000 VND). From Tuyen Quang city, you'll need your own wheels or a hired car to reach Lam Binh district — another 2.5-3 hours on provincial roads.
By motorbike: The most common approach. From Hanoi (하노이 / 河内 / ハノイ), ride north on QL2 through Viet Tri to Tuyen Quang city, then continue northeast on DT185 toward Lam Binh. Total ride from Hanoi is around 230 km, doable in a long day but better split over two. From Ha Giang city, head south on QL2 — about 150 km, mostly mountain road.
From Tuyen Quang city: Follow DT185 northeast through Na Hang town, then continue to Lam Binh. The turnoff to the waterfall is signposted (look for "Thac Ban Ba" in blue tourism signs). From the parking area, it's a 1.5 km walk on a dirt-and-stone trail to the main falls.
No Grab cars operate out here. If you don't ride a motorbike, arrange a private car through your hotel in Tuyen Quang city — expect 1,200,000-1,500,000 VND for a round-trip day hire.

What to do
Hike the falls trail
The trail from the parking area passes through bamboo forest before reaching the lowest pool. Budget 30-40 minutes each way. The path forks at the second tier — the left branch leads to a viewpoint overlooking the main cascade, the right drops down to a swimming hole. Wear shoes with grip; flip-flops won't cut it on wet rock.
Swim
The lower pools are calm enough for swimming from October through March. Water temperature hovers around 18-22°C — refreshing, not freezing. Don't swim during or immediately after heavy rain; flash floods are real.
Visit Tay villages
Several Tay hamlets sit within 5 km of the falls. Stilt houses, small-plot rice farming, and "ruou ngo" (corn wine) distilling. If you're staying at a local homestay, your host can introduce you to neighbors. Don't just wander into homes unannounced.
Combine with Na Hang Lake
Na Hang Reservoir (about 25 km southwest) offers boat trips through flooded karst scenery. Pair the two for a solid two-day loop from Tuyen Quang city.
Where to eat
There's no restaurant at the waterfall itself — bring snacks and water. In Lam Binh town (15 km away), a handful of "com binh dan" (everyday rice) shops serve standard northern Vietnamese plates: rice, stir-fried greens, braised pork, tofu, soup. Meals run 40,000-60,000 VND.
Na Hang town has slightly more variety: grilled stream fish, "thit trau gac bep" (smoked buffalo), and hill-tribe style sticky rice with sesame salt. Try the local "[pho](/posts/pho-vietnam (베트남 / 越南 / ベトナム)-noodle-soup-guide)" — it's beefier and less refined than Hanoi's version, served with extra herbs from backyard gardens.
If you're staying at a homestay, meals are included and typically feature home-raised chicken, foraged vegetables, and rice wine. Some of the best eating in the region happens at these family tables.
Where to stay
Homestays in Lam Binh: Basic but genuine. Expect a mattress on the floor of a stilt house, mosquito net, shared bathroom, and meals cooked by your host family. Around 200,000-350,000 VND per person including dinner and breakfast. Book through your hotel in Tuyen Quang city or call ahead — phone numbers are posted on local tourism boards at the district office.
Na Hang town: A few guesthouses and one or two mini-hotels with private rooms, hot water, and wifi. Rooms from 300,000-500,000 VND/night. Nothing fancy, but functional.
Tuyen Quang city: If you want a proper hotel with air conditioning and reliable hot water, base yourself here and day-trip to the falls. Muong Thanh and Vinpearl have outposts; budget hotels cluster around the central market area from 400,000 VND up.

Practical tips
- Entrance fee: 20,000 VND (as of 2024). Paid at the parking area.
- Phone signal: Viettel works intermittently near the falls. Download offline maps before you go.
- Cash only: No ATMs in Lam Binh. Withdraw in Na Hang or Tuyen Quang city.
- Leech socks: If visiting June-September, tuck your trousers into your socks or buy proper leech socks. They're harmless but unpleasant.
- Trash: Pack everything out. There are no bins on the trail.
Common mistakes
Underestimating travel time. Google Maps says 2.5 hours from Tuyen Quang city, but mountain roads with slow trucks and livestock crossings make it closer to 3-3.5. Don't plan this as an afternoon add-on.
Coming in deep winter expecting big water. January-February flows can be disappointing. If the waterfall is your main draw, aim for late rainy season.
Wearing the wrong shoes. The trail is short but rocky and often muddy. Sandals lead to twisted ankles.
Skipping Na Hang. If you've driven all the way out here, take the extra day. The reservoir boat trip is one of the most underrated experiences in northern Vietnam.
Final note
Thac Ban Ba rewards the kind of traveler who doesn't need everything polished. The road is long, the infrastructure is basic, and you won't find an English menu within 50 km. But the payoff — swimming under a jungle waterfall with nobody else around — is the kind of thing that's getting harder to find in Vietnam. Go before that changes.
