Qalai Khumb is a rather non-descript place, halfway between Khorog and Dushanbe on the Pamir Highway. Geographically, it looks like the perfect stop-over, but the place has little of the charm of other villages around.
Instead, we recommend the village of Yoged 30 km west of Qalai-Khumb. There is a nice homestay (OSM / Gmaps), lovely walks above the village, and several shrines you can visit.
Just beyond Yoged, you can go animal spotting in the Darwaz range (but you need a permit).
Qalaik Khumb practical
Qalai Khumb is a good place for a meal, though. Oriyono, located right next to the central bridge, has a superb view from its river balcony.
The town has several more restaurants, a basic market and a petrol station.
There are plenty of places to stay in Qalai-Khumb as well. Karon hotel is the most expensive and eye-catching hotel, but browse around and you will find a bevy of simpler hostels and homestays. Guesthouse Roma and the house of Bakhrom Sangakov have come recommended. More tips are welcome.
Border crossing and border market
5 km east of Qalai Khumb is a bridge over the Panj river, in the village of Ruzvai. The border crossing is open to foreigners, but it closes frequently. The same goes for the weekly border market.
Your questions and reports are welcome in the Ruzvai – Nusai border crossing forum thread.
