A moderate grade, meticulously smooth, alternating inclines and rests, and the descent is easy on the knees. This makes it a great descent trail for hikers. The hike is rated easy.

Snowshoeing at Picture Rock Trail at Heil Valley

Saturday, February 27, 8:00am

Despite its lower elevation, Heil Valley Ranch has good snowshoeing conditions for most of the winter. With plenty of shady areas, the snow is ample in this area longer than in other lower elevation parks. The most challenging trail here is the Picture Rock Trail, a 5.2 mile trek with a decent amount of elevation gain. The hike is rated moderate.
