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 makes for a long steady climb and a pretty blazing descent back down, but there are a few technical places along the way which will slow you down.
On top it connects with a trail that traverses much of the Khonkhor Hills South system from NW to SE. This upper trail, called Upper Traverse, will directly or indirectly connect you to pretty much all the other trails. So using Wild Horses and Upper Traverse, you can access several other trails and make some nice loops.
