Okay, so maybe these aren't exactly waterfalls, but this section of Panther Creek, just off of the Dominion Walking Trail, features a beautiful babbling brook perfect for getting lost in thought and putting the wheels in motion.
(The cache does not require bushwacking. Look for the short path to the creek visible from the walking trail. Cache location is a few feet to the west of the posted coordinates.)
If you're looking to exercise, Dominion Trail offers a bizzare "Fitness Challenge" along the stretch near this cache. Some of these challenges genuinely require Olympian-level athleticism; others are more like elementary-school playground games. I have no idea why these things were installed. Also look out for evidence of the old ranches which once dotted this area.
