From the intersection of Highways 43 and 21, take Highway 21 south for 1.2 miles. Just before the bridge across the Buffalo River, turn right onto the gravel road called Cave Mountain Road. This road starts with a curving drive up the steep side of a mountain. Fun! You don't need a four-wheel drive, but the road can get bumpy. The hiking area is part of the Ozark National Forest near the Buffalo River. Drive 6 miles (from the turn off Highway 21) to the Upper Buffalo Wilderness Area parking lot on the right. As a reference, you'll pass the Cave Mountain Church and cemetery on the right at 5.4 miles.
The next phase of your adventure leads you down a well-marked trailhead (N 35° 54 100 W 93° 27 617). Cross the street from the parking lot and you'll see the trailhead. The hike from here is about 3 miles "out and back."
After about a mile, you'll see a fork. The hike continues around the crest of the cliffs. If you've got small children, you might consider the woods hike (left) rather than the cliffs (right). Either way and you'll end up at the Hawksbill Crag overlook. Be sure to bring your camera for some great photos.
The cache is in a plastic box with a log book. Take a picnic lunch. The view is fantastic. Muggles have found and destroyed it twice in the past, so please re-hide carefully and cover your tracks.
Special thanks to Jerry Turner and BiloxiBear for notifying me about muggle attacks and ozzfreak for resetting the cache.
