East Valley

This is a 4.5 mi (7.2 km) dirt road climb into the trail system (or descent out of the system). It begins with dirt road near Khonkhor. Then it dwindles down to two track as you get into the mountain valley. It climbs/descends 640 feet over the 4.5 miles, so it is quite gradual (~140′ …

Moon Mountain Pass

One mile up to the top of the pass on each side. The NW side is an 850′ ascent/descent, and the SE side is 600′ of ascent/descent. The trail makes a stiff but fun return trail after riding down the Upper Traverse Trail and any of a few trails connecting to the East Valley Trail. …

Two Dogs Extension

This is a 2.75 mile loop that begins with a blazing fast 1.1 mile singletrack descent through a beautiful Siberian white pine and Siberian larch forest. This singletrack descent is followed by a 1/2 mile gradual dirt road descent, which is in turn followed by a challenging 1.1 mile 975 foot ascent heading back up …

Nukht East Ridge

A big steep one mile climb with lots of hike-a-bike followed by a really nice two mile descent. This makes for a good starting trail to ride across the entire network in the Yarmag Hills system. The entire trail is 4.35 miles long if you ride it out to the road, but the last half …

Yarmag Hills

These trails lie on the NW facing slopes of Bogd Uul between the Yarmag Bridge (over the Tuul River) to Nukht Amaralt (camp). This is a seven square mile area (18 sq km and 4500 acres). The trails are steep two track and singletrack, heading pretty much straight up and down the mountain slopes for …

Lower Tur Norakh Gol

The trail runs along the south side of the creek and along much of the north boundary of trail system/network (Khonkhor Hills South). Over its 4.1 miles, the elevation change is roughly 650 feet. The surface is mostly tame. The main asset of this trail is serving as access to a few of the better …

Upper Traverse

This trail runs along and near the top ridge of Bogd Uul on the far SE end of the mountain. It runs 5.5 miles and is generally best ridden NW to SE as it descends 1320 feet in that direction and only ascends 675 feet. This trail serves as the main connector trail across the …

Wild Horses

This is a 4.1 mile climb up the mountain to the top (and back down if you choose to do it as an out and back). It starts as a two track, and after about a mile or so, it dwindles down to narrow singletrack. It is about a 1750′ ascent to the top which …

Two Dogs

Head west from the THD on a 4WD two track. Go about quarter of a mile (~0.5km), and you will reach a small opening in the forest. Here you can continue in multiple directions — north, south or west. Do not head south. That leads you to the Chengeltei Mountain South trails. If you head …

Zaisan Trail

The trail heads south out of the back of Zaisan Camp. It continues south up the mountain for 2.25 mi (3.6 km) until you reach an open meadow on top. It is a 1700′ climb. So it is a pretty brutal climb. It is also makes for a fairly technical rippin’ descent with a lot …

Zaisan West Ridge

This is a technical point to point ride with several sections that are very steep. The technicality ranges from intermediate to double black. It is mostly rocky, but there are also rooty areas and organic areas. The trail initially heads south out of the backside of Zaisan Camp up the main Zaisan Trail (not Zaisan …

Selkh Am West Ridge

This is a big ridge that is quite complex. You have to piece together two tracks and small singletracks to work you way south down the ridge. The area is a mix of big climbs, blazing descents, pretty forests, barren rocky slopes, and outstanding views. It takes a lot of physical effort and a lot …
