Khustain National Park
This approach to Tsetseegün from the south side is the easiest route by far. As you face the monastery, cut over to your right (east) until you get to the stream. Just follow the stream until it nearly disappears and then head north. About three hours’ walking should bring you out over a ridge into a broad boggy meadow, which you’ll have to cross.
Horses are available from Stepperiders Camp, just off the main Ulaanbaatar–Zuunmod road. Stepperiders is run by Minde, a recommended local horse guide who can give lessons, instructions and support to independent travellers planning their own expedition.

For more sedate walks in the Terelj ger camp area, just follow the main road and pick a side valley to stroll along at your leisure. From the main road, look out for interesting rock formations like Turtle Rock, in a side valley to the south of Terelj, which really looks like one at a certain angle.
The best tour operator is Morin Jim, a French-run operation based at Morin Jim Café. Horse trips cost T20,000 per day per horse, plus the same again for your guide.
