The Frost Trail is a short (1.18 mile) trail that runs up hill to the site of the old Frost Fire Lookout tower. There are a couple of very steep hill climbs and a few sections that have the usual tree roots sticking out into the trail. When wet this would be a very very difficult trail due to the hill climbs. When dry, this is a fairly easy trail. Stock Jeeps should not have any problems with the Frost Trail. The final 150 yards of the trail are a steep climb up to the top, and a little narrow with a drop off the right side that may have your passenger closing their eyes. To top it off, there is a gathering of rocks near the top on the left side of the trail that cause you to tilt a bit off-camber to the right. The trail tops out at around 5725' and offers a 360 degree view that includes Mt. Rainier and the Stewart range to the north. Due to the fact that this trail is well removed from the other trails on the Manastash ridge, it seems as though it gets little use and therefore it is in good shape.
