This hike uses the Sid Davis Trail to summit San Jacinto. It's the shortest route and is only really accessible when there is more than 2 feet of snow on the ground. We crampons or microspikes are mandatory and snowshoes advisable as the trail climbs straight up to Miller Saddle. Miller Peak is 100 years east of the saddle junction, so you might as well bag that while there. During summer, this route is covered in chinquapin and not really accessible unless you want to do some bushwhacking. The waypoint is at the junction with the main trail. The trail is NOT marked, but there is a sign in a bend where the trail crosses the creek directing you to Round Valley (to the left). You go right and stay on the right (north) side of the creek from there on.
