High Rock, FS 8440, located in the Gifford Pinchot National Forest a few miles south of Ashford, Washington, takes you to two popular hiking trails, High Rock #266 and Greenwood Lake #253. These top-rated hiking trails climb to even higher elevations. This straight-through road connects FS-85 and FS-84, climbing through lush old-growth forests to its highest elevation of 4308 feet, with beautiful views of the surrounding peaks and valleys below. At the top of the climb is a large parking area with stunning views of the cascades to the east.
There is one camping spot about two miles in on the road, but many side roads offer different camping areas.
The road has water runoff damage, but the effects are minimal with a 4x4 high-clearance vehicle.
