The Khentii Mountains start immediately northwest of Ulaanbaatar, and continue to the Russian border. This wild area is very reachable. One hour driving out of Ulaanbaatar and you will be alone. Terelj is a tourist destination with ger camps, it is known for its beautiful countryside with alpine  surroundings, many rocky formations and wild flowers blooming, including edelweiss and several species of orchid.  

A little further the paved road ends and you have to cross the river by 4WD vehicle. After this you will arrive in an extensive wilderness. Close by there are usually some nomad families, however closer to the Russian border it is largely uninhabited and it is a forested area with many wild animals including deer, bears, wolves, and foxes. It is a perfect place for rough (long) treks, From Terelj you can also make less strenuous trips where you can also visit nomads.

• Stay the night in a nice luxurious private ger in a ger camp, and go trekking and stay at local friendly nomads, coming back via canoe down the Tuul River.
