Rock-Climb
TRAVEL: 49 MILES
Trek through Tohickon Valley Park toward the 200-foot shale cliff known as High Rocks. The wall is craggy enough to give both experienced and newer climbers a workout and, once summited, offers expansive views of the Tohickon Creek valley. When the sun starts to dip, camp near the banks of the creek (campsites from $15; buckscounty.org).

Road-Bike
TRAVEL: 85 MILES
Spin through the sleepy countryside of Lancaster County. This 84-mile road ride (lancasterbikeclub.org) through the Susquehanna Valley features 6,000 feet of climbing and the chance to break at Susquehannock State Park (padutch.com/z/susquehannocksp.htm). Afterwards, roll into the Harvest Moon Bed and Breakfast, in nearby New Holland, where the innkeepers are also your personal chefs (doubles from $99; harvestmoonbandb.com).

Eat
TRAVEL: 130 MILES
Go green at Natural Acres, an organic farm in Millersburg that recently opened a five-room bed-and-breakfast serving raw-milk cheeses, farm-raised organic eggs, and homemade white spelt bread (doubles from $65, including breakfast; naturalacres.com).

Paddle
TRAVEL: 309 MILES
Canoe down the placid Clarion River in Cook Forest State Park, a sprawling 8,500 acres of woodsy goodness that features some of the tallest and oldest trees in the country—including white pine and hemlock. Then step ashore to explore the park's more than 30 hiking trails, or cast a line in the Clarion, chock-full of trout, bass, and catfish, before sleeping in one of 22 cabins or at one of hundreds of campsites (campsites from $15; cookforest.com).
