Khentii hotels and hostels
Khödöö Aral
Run by Ikh Zasag University, it's not a particularly attractive ger camp, but it does have hot showers. It's 7km west of the Avarga Resort.
Onon
Between Gurvan Nuur and the village, by the monastery, is this ger camp, which opens in summer when there is demand, which isn't often.
Jargalan Hotel
Once a government guesthouse, this place limps along as a hotel. Rooms are falling apart and hot water comes in a thermos; some have a TV, although it shows just one channel. If the hotel is empty the manager is open to bargaining.
Khongor's Ger Camp
Next to the Naadam Stadium, this new place that has basic accommodation and meals.
Erdes Hotel
This overpriced Soviet dinosaur with its grumpy staff might be your only option, as hotel rooms are scarce in Öndörkhaan. The standard rooms are pretty dishevelled and use a shared bathroom so you might want to splash out on a half-lux room.
Khuvchin Jonon
About 350m north of Government House, this newly constructed hotel offers 17 comfortable rooms, and is the best Öndörkhaan has to offer. It's clean and the staff runs a tight ship.
Chinggisiin Gurvan Nuur
This resort has a nice location on the shore of a lake about 2km from Dadal village. Meals are around Tug1500. There are no gers. A good hiking trail starts from the back of the camp.
Avarga Resort
This is the place to come if you have a burning desire to join Mongolian families on holiday. The rather run-down resort offers hot-water bathrooms or you could bury yourself in mud on the shores of the lake.
