Looking for some info. on the trail system in Iron county, we are thinking of riding from Mercer up to Hurley in the next couple of weeks. I see a trail 8 marked in purple on the map that is listed as very difficult, has anyone been on this trail and if so what makes it very difficult? Would be looking for a good place to park and ride for the day or a good place to stay over night both in Mercer. Any info. about the area and general trail conditions would be greatly appreciated.
