This is a magical place; you can see why the tribes thought so much of it for so many thousand years. It’s a little tricky to find, but worth the trouble: an eroded red sandstone slot canyon carved into the edge of the Bighorn National Forest, one huge wall is covered with unusually clear petroglyphs—and they’re not only easy to get to, they’re wheelchair-accessible (some are up a hill, but most are along a mostly-flat gravel path). There are pamphlets to help you decipher the petroglyphs, a physical timeline to help you grasp the passage of time (the canyon has been inhabited for at least 10,000 years), a beautiful trout stream that has undercut the sandstone on the other side of the canyon, forming deep shady overhangs and caves—we saw a tiny bat swooping down from the overhang to get a drink one time; a little nature center with pamphlets that describe the sights along a lovely, mostly shaded, numbered walking path; improved campsites (currently $17 a night for out-of-state campers in high season), picnic areas, multiple hiking paths, restrooms, horse facilities (call ahead to arrange)plenty of parking, and a beautiful little old-fashioned white clapboard farmhouse inhabited by some of the luckiest SOBs on the planet ;-). The only time I’ve ever seen it really crowded was Fourth-of-July weekend, and even then there was plenty of elbow room—just no camping sites available, but lots of places to picnic or park and stroll. Bring your curiosity and reverance, and you’ll be impressed.
