This wide, level trail can be used for a half-day walk and a pleasant picnic along the Middle Fork American River.  It goes through some of the best scenery available in the American River Canyons, and picnic tables are provided along the first 1¼ miles of the trail.  For those looking for a good workout, this trail is 11.2 miles round-trip.  Several side trails are accessible that can be used to create even more challenging loops.  There is little shade, however, so take plenty of water and sunscreen on hot summer days.
