If you park down at the circle you'll have to run up the road before getting on the trail.
This the longest single trail around Sugarloaf Mountain. It is easy terrain but watch for horse and bike traffic during the summer.
Around the north side of the trail you can extend by going on the Blue Trail (Northern Peaks Trail)
or Purple Trail
sections before returning to this loop.
Utilize the White Trail (Mountain Loop Trail)
to connect to the center sections if you want to go to the summit.
