Though this trail is mostly 4x4 road and two track, it is a spectacular ride for its beauty, adventure and biking. Start at the village of Hatgal and head north along the eastern shore of the lake. Go all the way around the northern tip of the lake and finish on the northwest shore at the bay across from Dulaan Uul (Warm Mountain). Dulaan Uul protrudes out from the western shore to form the bay. At this location you are truly at the ends of the earth just below the Mongolian Siberian border.
Along the 145 mile journey (233 km), you will ascend and descend 16 small mountain passes. Only a handful of them are truly difficult, and all 16 add some nice variety to the trip and some really nice DH runs.
There is only one supply point along the way. That is the tiny village of Khankh on the NE shore. This is about 100 miles into the trip and is the only point of civilization. Unless you want to ride both directions, it is necessary to have a vehicle pick you up on the NW shore. You can ride this unsupported and have a vehicle pick you up at the end. Or you can ride this supported and enjoy a few of life's comforts each night.
There is a ton of opportunity to get off the 4WD road and ride some of the big slopes of short grass. Many have no trail; you just pick your lines and let it rip (backcountry freeriding). There are also various rocks to session on along the way. You can take on as many diversions as you like and extend the trip for as long as you like.
After you leave the lower southern portion of the lake, you will likely only see two maybe three nomadic herdsmen families along the way until you get to Khankh. This is a truly remote XC adventure in exceptionally beautiful wilderness.
