What it is
Thac Dray Sap sits on the Serepok River about 30 km south of Buon Ma Thuot, the capital of Dak Lak province in Vietnam's Central Highlands (중부 고원 / 中部高原 / 中部高原). The name comes from Ede language — "Dray Sap" roughly translates to "smoke waterfall" — and once you see the mist rising off the basalt ledge during wet season, the name makes sense.
The falls drop around 20 meters across a wide curtain of water that stretches over 100 meters during peak flow. The basalt columns framing the cascade are volcanic remnants, maybe 100 million years old, giving the whole scene a geological weight that most Vietnamese waterfalls lack. Downstream, Thac Dray Nur (its twin waterfall) is connected by a short trail, and most visitors do both in a single trip.
Why travelers go
Honestly, most foreign tourists skip the Central Highlands entirely. That's a mistake. Thac Dray Sap offers something different from the coastal waterfalls: raw volcanic landscape, Ede cultural context, and almost no tour buses. You'll share the trails with domestic visitors and local families, not backpacker crowds.
The area also works as a half-day escape from Buon Ma Thuot if you're already there for coffee plantations or elephant-ethics tourism. The combination of red earth roads, coffee forests, and basalt geology feels distinctly highland — nothing like Ha Long Bay or Phu Quoc.
Best time to visit
The Central Highlands wet season runs roughly May through October. The falls peak between August and October when the Serepok is swollen. This is when the "smoke" mist is thickest and the full width of the cascade is active.
Dry season (November–April) means lower water levels. The falls don't disappear, but they thin out considerably — by March, you're looking at several separate streams rather than one unified curtain. The upside: trails are less muddy, and you can walk closer to the base.
Sweet spot: late September or early October. Full flow, but the heaviest rains have usually passed.
How to get there
From Buon Ma Thuot
The falls are in Krong Ana district, about 30 km south of the city center. Options:
- [Motorbike rental](/posts/renting-motorbike-vietnam (베트남 / 越南 / ベトナム)-legal-insurance): 120,000–150,000 VND/day from guesthouses near Nguyen Tat Thanh Street. The ride takes 40–50 minutes on QL14 then a signed turn-off onto a smaller road. The last 3 km is concrete but narrow.
- Grab car: Around 200,000–250,000 VND one way. Ask the driver to wait (negotiate 50,000–80,000 VND/hour waiting fee) or you'll struggle to find a return ride.
- Guided tour: Local tour operators bundle Dray Sap + Dray Nur + a coffee farm for 400,000–600,000 VND per person including lunch. Ask at your hotel.
From further afield
Buon Ma Thuot has a domestic airport (BMV) with flights from Hanoi and Saigon. From Da Nang or Hoi An (호이안 / 会安 / ホイアン), it's a long drive — roughly 6 hours — so most people fly or take a sleeper bus from Saigon (8–9 hours, around 250,000 VND on Phuong Trang or Thanh Buoi lines).

What to do
Walk both falls
Entrance ticket covers both Thac Dray Sap and Thac Dray Nur. The path between them is about 1 km through forest — mostly shaded, some stairs, nothing technical. Budget 2–3 hours for both falls plus photo time.
Swim (with caution)
There are shallow pools at the base of Dray Sap during dry season where locals wade. Wet season currents are dangerous — don't get in the water when the river is high. No lifeguards, no barriers.
Suspension bridge
A cable bridge crosses the river between the two waterfalls. It sways. It's fine structurally but not for anyone who dislikes heights. The view from the middle is the best vantage point for Dray Nur.
Cultural context
The Ede and M'nong communities consider the Serepok River sacred. Some tour guides from Buon Ma Thuot are Ede themselves and can explain the local legends. If you're into ethnographic travel, pair the waterfall visit with a trip to a nearby Ede longhouse village — Buon Don or Buon Jun on Lak Lake.
Where to eat
There's a small food court inside the waterfall park — basic "com binh dan" (everyday rice plates) for 30,000–50,000 VND. Grilled chicken and bamboo-tube rice ("com lam") show up on weekends when vendors set up near the parking lot.
For better food, eat in Buon Ma Thuot before or after. Try "bun do" (a local red noodle soup) at the market stalls near Cho Buon Ma Thuot, or get com tam at one of the rice-plate shops on Le Hong Phong Street. Vietnamese coffee (베트남 커피 / 越南咖啡 / ベトナムコーヒー) here is obviously excellent — look for any shop advertising "ca phe chon" (weasel coffee) if you want the local specialty, though a standard "ca phe sua da" at 15,000–20,000 VND is perfectly good.
Where to stay
Nobody stays at the waterfall itself — there's no accommodation. Base yourself in Buon Ma Thuot:
- Budget: Thanh Binh Hotel or similar on Ly Thuong Kiet Street, 200,000–350,000 VND/night.
- Mid-range: Muong Thanh Buon Ma Thuot, around 600,000–800,000 VND. Clean, central, decent breakfast.
- Homestay option: Lak Lake homestays (M'nong stilt houses) are 60 km south — combine with the waterfall as a two-day loop through the highlands.

Practical tips
- Entry fee: 30,000 VND per adult (as of 2024). Parking is 5,000–10,000 VND for a motorbike.
- Footwear: Wear shoes with grip. The basalt near the water is slick, especially in wet season. Flip-flops are a bad idea.
- Cash only: No card payment at the park or food stalls. ATMs are in Buon Ma Thuot — withdraw before you leave town.
- Sun + rain: Bring both sunscreen and a rain poncho. Highland weather shifts fast, especially June–September.
- Phone signal: Viettel works fine at the falls. Mobifone is patchier on the access road.
Common mistakes
- Only visiting Dray Sap and skipping Dray Nur: Dray Nur is arguably more photogenic — wider, more accessible at the base. Don't skip it.
- Coming in March expecting full flow: You'll be disappointed. Time your visit for late wet season.
- Not budgeting enough time: People assume "it's just a waterfall" and allocate one hour. With the walk between both falls, photos, and a swim, three hours is more realistic.
- Wearing white: The red basalt dust and mist will stain light clothing. Dress accordingly.
Final note
Thac Dray Sap isn't a bucket-list attraction — it's a regional highlight that rewards travelers willing to leave the coast. If you're passing through Dak Lak for coffee tourism or heading between Da Lat (달랏 / 大叻 / ダラット) and the highlands, carve out a half day. The volcanic geology alone is worth the detour.
