The Pleasant Valley Loop Trail traces the edges of Pleasant Valley in a dense old-growth forest with the largest specimens of western larch anywhere in the state. The trail south of the highway is ungroomed and can have obstacles like rocks or tree wells depending on snow depth, but is very scenic as it traverses silent woods and the icy banks of the American River. The lower 3/4 of the trail north of the highway is usually groomed and rated easy to intermediate. There are four Sno-Parks along the way where you can park, but the lowest one, Hell's Crossing is the easiest to get to and allows the longest loop. A Sno-Park permit is required to park your vehicle at the trailhead. Dogs are generally not allowed on groomed trails.
