Anyone know if there are any trails up in the Chadron/Alliance area of the state?
I found some 2 track trails in the Nebraska National Forest. One starts in Chadron State Park. You will need some pretty detailed Topo maps and be prepared to turn around. there is a mix of public and private lands.

The "trails" I found were not the least bit difficult, but it was nice to get off the highways and farm roads and up into the hills. Could be busy during hunting season. Here is a picture I took from our campsite in the area years ago...
