Paddle
TRAVEL: 45 MILES
Kayak Class III rapids on the Mirant Power Plant's 16-year-old artificial course with Tsangpo veteran Tom McEwan's outfit, Liquid Adventures ($110; liquidadventures.org). Located in Dickerson, Maryland, the course is a training center for the USA Canoe/Kayak National Whitewater Slalom Team.

Rock-Climb
TRAVEL: 136 MILES
Send the Narrows, a 1,300-yard cliff band of sandstone from 20 to 200 feet high, full of ledges, horizontals, and imposing roofs, just outside Cumberland, Maryland. Nearly unclimbed until 2002, it now has close to 100 established routes ranging from 5.2 to 5.10+, including multipitch and some top-roping. While there, stay at the Stonebow Inn, a bed-and-breakfast in nearby Grantsville, where you can cast for trout on the Casselman River ($135; stonebowinn.com).

Hike
TRAVEL: 147 MILES
Explore Assateague Island National Seashore's backcountry, a sublime 48,000 acres of wilderness on the Atlantic seaboard. There's the pounding Atlantic surf on one side, Sinepuxent Bay on the other, and, in between, rolling sand dunes, pine forests, and green salt marshes where wild ponies and sika deer roam. With no potable water available, chances are you'll be one of the few at any of the waterfront's six first-come, first-served backcountry campsites (from $5; nps.gov/asis).

Mountain-Bike
TRAVEL: 241 MILES
Tear up the 100 miles and 1,500 vertical feet of doubletrack, singletrack, and fire roads spread over 11,000 acres at West Virginia's Snowshoe Mountain. Or tackle the four-year-old bike park, featuring ladders, jumps, and drops ($37; ride.snowshoemtn.com). At night, recover in the hot tub at the Rimfire Lodge (doubles from $154; snowshoemountain.com).
