MOUNTAIN BIKE
The San Juan Hut System (Ridgway, Colo.; 970/626-3033; www.sanjuanhuts.com; $475, including lodging and meals) consists of six wooden cabins along the 206-mile bike path between Telluride, Colorado, and Moab, Utah. The entire trip takes a week, but you can fashion a long weekend itinerary on the trails from either starting point.

KAYAK
In the mid-1800s Port Townsend, Washington, was a booming seaport with grandiose Victorian mansions all over the fashionable "uptown" quarter. Nowadays, the town—surrounded by water on three sides—is a perfect place for dipping an oar. PT Outdoors (888/754-8598; www.ptoutdoors.com; half day $45; daylong $76) leads kayak tours around Discovery Bay and to Protection Island, a National Wildlife Refuge that's home to elephant seals, sea lions, and bald eagles.

HIKE
The Allegheny Front Trail circles the forests and wetlands of the Black Moshannon State Park in central Pennsylvania (814/765-0821; www.dcnr.state.pa.us), providing a 40-mile hiking route through rough terrain. The ridges just south of Route 504 offer the best views.
