Heading up in 10 days. I have tracks for a couple of loops but would like other options. Most of us will be on small dirtbikes so gnarly tracks are welcome!
Did you ever find any tracks for this area? I am heading up sometime this weekend, looking for some nasty trails.
Excellent national forest map of the entire system. This is what I've always used and never had any problems. GP is definitly under snow until late june early july. One of my favorite places to ride, check out trail 261. Big bikes not welcome on these trails.
OHVtrails.net supported by Trail tech has gpx files for the majority of the little bike trails in the GPNF. I rode several of them over the past weekend and they were pretty spot on.
