There's a zillion places to hike in and near the Twin Cities. A favorite is the 20 miles of trails that wind through oak savannas and ravines along the bluffs of the St. Croix River at Afton State Park. Wander through restored prairies or along beaches, then hike to the edge of vistas overlooking the river valley, where you might spot bald eagles soaring overhead. Most visitors do day-hikes, but 28 backcountry campsites are available for the more adventurous. There are picnic and swimming areas, too.
