Schallenberger Ridge Loop begins by following the California Trail, the same trail pioneers traveled on, as it wanders through Coldstream Valley and follows alongside Cold Creek to Merrill's Ponds. From here, it follows a snow covered road and logging road to Schallenberger Ridge where you'll find excellent views of Donner Lake below and mountain vistas. To complete the loop, the trail makes a cross-country trek as it descends along the ridge back to the trailhead.
