This is an unusual entry for a trail, but oh is it fun ... ... and so different from the rest of the riding in Mongolia. The backcountry of Mongolia is a mountain biking paradise in pristine landscapes. You can drive 10 minutes out the capital or for days and find biking all along the way. However, you don't even have to leave the capital to find some fun.
Our family lives in District 15 of "UB" (Ulaanbaatar), and the district itself is a blast to ride. It sits on a hill and has dirt track, banks, drops, short chutes and obstacles everywhere. It's hard to visualize unless you have been here. The conditions are pretty much inner city, but with less cement and lots of dirt. =) Check out the photos to get a feel for the fun to be had. It's kind of cool too to realize that District 15 is only 2 miles from the Mongolian Parliament.
As you will see, there are advantages to living in a lesser developed nation as a mtber. Basically, District 15 is one of my main "after work" rides -- just roll my bike out the door and let the fun begin -- unless of course it is winter in Mongolia. Then one must sit and wait for the thermometer to find its long way back to near freezing temps again to get on the bike.
