There is a side trail leading from the PCT directly to Sawmill Campground climbing a hill for a quarter mile. The access from the road is not the official PCT. The campground has some picnic benches, fire pits, a pit toilet and trash cans. There is a water tank half a mile down the road leading to the campground.
A little bit of trail finding may be needed here in winter. The shortest is to head about 50 yards northwest off trail to reach the campground, or backtracking a bit later on a short side trail which can be hard to see when there is untouched snow on the ground. Car-campers use the access from Sawmill Motorway Forest Rd, where there's a water tank. Most sites have nice picnic tables, fire pits, and share trash cans and a pit toilet.
