This is an out and back ride -- up as you go out and down as you come back. The turn around point is Tsetsee Gun sacred place, which is the highest point of Bogd Khan Mountain (just over 2255m or 7400ft).
The trail is very well marked with yellow blazes and distance markers on many trees. I like to think of the trail in three sections. The bottom section is about 2.3 km long. It is steep and difficult going up and VERY fast coming down with enough tech and rock to really keep you focused.
The middle section is 2.5 km. It is not as steep as the bottom but still has a some slope to it. It is a root and rock jungle -- gnar everywhere. It's a tough "go" on the way up, but if you have the skill set, a huge blast on the way down, bombing through rocks and roots EVERYWHERE.
Finally, the upper section is a little more than a km long. It is pretty much a rock fest to the top. It is much flatter than the other two sections, so quite a bit slower going on the return than the other two sections.
All in all, I would rate this trail an upper intermediate to advanced trail because of all the gnar and the climb up is a tough workout, both pedaling and pushing the bike. Then to make all that effort worth it, you have to have a good enough skill set to really capitalize on the return DH run. It is 1900' up and then back down. On a scale of 1-5, I'd give the ride a 4.5 to 5 rating. I absolutely love it.
