The Keystone Aqueduct Trail is a beautiful trail up above the town. The trail is beautiful in the fall with lots of aspens. It's also a very popular mountain biking trail.
The trail from Keystone Gulch Trailhead starts out on the road next to a creek. Continue up the road for about a half mile. There will be a bridge on the right to cross the creek. Follow the trail around to the left. When you reach the big metal pipe with boards over it you will be very close to the cache. It is a small medicine bottle wrapped in duct tape.
