The surface is mostly smooth hardpack, but has some significant sandy stretches and some rocks to keep things interesting. Much of the route is on north-facing slopes, so it can be good in summer when other places are too hot. The downside is that these trails are slower to dry than some others in the area, so they may be too muddy in the colder seasons. As mapped here, the loop starts from Polecat Gulch trailhead, but you could alternately start from the parking area on Cartwright Road.

Note: As of 2021, all users are required to travel counter-clockwise on this loop (may not apply in the winter).
