The Cross-Country Ski Trail at Allegheny National Forest in Bradford, Pennsylvania is an easy and flat trail that leads from the Morrison Loop Trail / Rimrock Loop Trail parking lot and leads over to the road that leads up to the Rimrock Overlook.
We hit this trail at the end of the day looking for a campsite, but could not find any within the first 0.3 miles. The trail itself is flat, but the ground off to the sides of the trail is very wavy, which doesn't make it easy to camp on. It's a nice trail to hang a hammock and build a small fire. Camping is technically allowed off to the sides if you can find a good spot to setup shop.
Dogs are allowed on this trail.
Note: The entire length of this trail is closer to 1 mile one-way.
