Denau to Sariosiyo: The Road to the Sangardak Waterfall
Sariosiyo is a mountain district at the foot of the Hissar range, where the road to the Sangardak waterfall and the Tupalang Reservoir begins. How to get there, road conditions and when to go.

Northern Surkhandarya looks nothing like the hot plain around Termez. Here the spurs of the Hissar range begin, cold rivers run through the gorges and walnut and mulberry trees grow in mountain villages. Sariosiyo is a district town near Denau and the starting point for trips to one of the most beautiful waterfalls in Uzbekistan, the Sangardak waterfall, as well as to the Tupalang Reservoir. Here is how to plan the trip.
Distances and time
| Section | Distance | Travel time |
|---|---|---|
| Denau to Sariosiyo | about 20–30 km | 30–40 minutes |
| Sariosiyo to the Sangardak area | roughly 30–40 km | 1–1.5 hours |
| Denau to the Sangardak waterfall | roughly 60–70 km | 1.5–2 hours |
The road to Sariosiyo is flat and paved. Further into the mountains it narrows, with climbs, bends and stretches of imperfect surface. Travel time depends on the weather and road conditions, so allow extra time.
Getting from Denau to Sariosiyo
Minibuses. Marshrutka minibuses run between Denau and Sariosiyo from ranks near Denau market and bus station. The ride is short and cheap.
Shared rides. On Yo'ldosh, drivers who travel between Denau and Sariosiyo list their trips and you book a seat in the app. This is useful if you need to leave at a specific time rather than wait for a minibus to fill up. Drivers are verified, and a seat typically costs less than a taxi.
Taxi. To go further into the mountains, the easiest option is to hire a local driver for the day: they take you to the waterfall, wait and bring you back. Agree on the price and waiting time in advance.
The road to the Sangardak waterfall
From Sariosiyo the road climbs up the river valley past mountain villages. What you need to know:
- Surface. Asphalt gives way in places to worn sections and gravel. An ordinary car usually manages in dry weather, but with care.
- Bends and narrow sections. Oncoming vehicles sometimes need to squeeze past each other, so slow down.
- Weather. After heavy rain the road can be washed out or strewn with rocks, and in spring mudflows are possible. Ask locals about road conditions before you set off.
- Coverage. Mobile signal in the gorges is unreliable.
- Fuel. Fill up in Denau or Sariosiyo, as there are no filling stations higher up.
If you are not confident about mountain driving, it is better to go with a local driver who knows the road.
The waterfall itself
The Sangardak waterfall is a tall cascade dropping from a cliff in a green gorge. In spring and early summer, when the mountain snow melts, it is at its fullest. A footpath leads from the parking spot to the falls. The walk up usually does not take long, but you need comfortable shoes with good grip.
Safety at the waterfall:
- stay away from cliff edges and do not climb on wet rocks;
- do not swim in the icy pool at the foot of the falls, as the current and cold are dangerous;
- keep an eye on children on the path;
- do not leave litter or light fires outside designated places.
The Tupalang Reservoir
The Tupalang Reservoir lies in the mountains of the same district. Turquoise water framed by mountains makes it one of the most beautiful sights in Surkhandarya. People come here for the views and photographs. Swimming in the reservoir is unsafe because of its depth and cold water, so stick to walking along the shore where it is allowed. The restricted area around the dam structures is closed to visitors.
Mountain villages and local hospitality
On the way to the waterfall you pass villages where life moves at an unhurried pace: sheep graze on the slopes, apricots and walnuts dry outside houses and people fetch water from springs. Locals are usually welcoming and happy to point you in the right direction. If you are invited in for tea, it is a sign of respect; you can accept, but do not overstay your welcome. Buying fruit, nuts, honey and dairy products directly from villagers is a good way to support them and to taste things you will not find in town. Photograph people and homes only with permission.
When to go
- May to June: the waterfall is full, everything is green and the mountains are cool.
- July to August: the valley is scorching but the mountains are pleasant; the best time to escape the heat.
- September to October: dry roads, golden autumn, and the walnut and fruit harvest.
- November to March: cold in the mountains, possible snow, and the road may be impassable. Not the best season.
- March to April: beautiful, but a high risk of mudflows and washouts after rain.
A one-day plan
- 7:00 a.m.: leave Denau.
- 7:40 a.m.: a short stop in Sariosiyo to buy water and snacks.
- 9:00 a.m.: arrive at the waterfall for a walk and a rest.
- 12:00 p.m.: lunch in a mountain village or a picnic.
- 2:00 p.m.: head back, stopping at the reservoir if you like.
- 5:00 p.m.: back in Denau before dark.
What to bring
- Comfortable footwear for the path and a light jacket, as it is cooler in the mountains than in Denau.

- Cash to pay the driver and to buy from local people.
- Your passport, as checks are common in border districts.
- A first-aid kit and sunscreen.
The way back
It is best to come down from the mountains in daylight. Minibuses run from Sariosiyo to Denau during the day, but there are few in the evening. If you need to leave at a particular time, find a ride in advance on the Sariosiyo to Denau page.
You can find a ride from Denau to Sariosiyo on your date on the Denau to Sariosiyo route page. The for passengers section briefly describes how booking works.
