|BEST PLACE TO:
||Upwards of 50 sport and traditional one-pitch climbs (ranging from 5.6 to 5.12) pepper the Tongue River Canyon in Bighorn National Forest near Dayton. Pick your way up dolomite pockets, cracks, or bulges.
||All the routes face south and can get hot in summer. Big Bird (5.9), Edward's Crack (5.8+), and Hang Dog City (5.11+) have roofs that keep the climbs rain-free.
||Take Interstate 90 north from Sheridan to U.S. 14 west; go right on County Road 92 and about two miles to a parking area. A trail leads to the crag (don't cross the bridge), about a quarter-mile up on the right.

||Dozens of remote alpine lakes, reached by hiking along the 45-mile Solitude Loop Trail, are filled with cutthroats, rainbows, and browns.
||At Lake Solitude, eight miles north of the West Ten Sleep trailhead on the Solitude Loop Trail, scores of hooked cutthroats will wear out your click drag.
||Four main trails spin off the circuit, but those at West Ten Sleep (70 miles west of Buffalo) and Hunter Corrals (20 miles west of Buffalo) are well-marked and easily accessed from U.S. 16.
||For guided trips or fishing permits (nonresident one-day permit, $6; annual license, $65) visit Big Horn Mountain Sports in Sheridan. Many areas only allow artificial lures.
||You won't need ropes or other hardware to explore novice-friendly Tongue River Cave. Experts will want to find 1,403-foot-deep Great Expectations, on the mountains' western flank, but few will brave its infamous tunnel, "Grim Crawl of Death."
||Go deeper into Tongue River Cave for graffiti-free rock formations. You'll need three days for Great Expectations; be ready to rappel down waterfalls and slither through a water-filled tunnel with little breathing room above the chilly, 37-degree stream.
||Tongue River Cave: Hike toward the crag in Tongue River Canyon (see Climbing, The Spot, above) and cross the bridge. The cave's a quarter-mile away. Great Expectations: You'll need a local caver to find and unlock its gated opening.
||Call the Bureau of Land Management at 307-347-5100 for information on Tongue River Cave. The Hole in the Wall Grotto (PO Box 4074, Casper, WY 82604) keeps the key to "Great X"—but you'll need connections to get in.
||The thermals at Sand Turn, a leeward cliff launch at 6,495 feet, carry gliders up 2,000 feet or more over rocky gorges and ravines. A paved parking area has room to assemble at least ten gliders.
||Thermal-sailing along the rock faces shooting up from the Tongue River is best in late morning. The daring will soar up to 11,000 feet and cruise the Bighorns' 40-mile spine.
||Follow U.S. 14 west from Dayton for about ten miles to the marked launch at the Sand Turn scenic lookout. Favored landing zones include the football field in Dayton and a clearing at the mountain's base.
||Johann Nield, a local hang gliding instructor, will provide information or take you out ($75 for three hours of lessons; weekdays 307-655-2217, weekends 307-751-6761).
