Sitting in the scenic heart of the Green Mountains, at the junction of US-4 and Route 100, Gifford Woods State Park (802/775-5354) protects one of the few virgin hardwood forests left in New England, with seven acres of massive sugar maple, birch, and ash trees, some of which are more than 300 years old. There’s a nice campground (campsites around $20, cabins around $50) with hot showers, four one-room cabins, and access to many fine trails, including the Appalachian Trail and the Long Trail, which run together across US-4 just west of 2,190-foot Shelburne Pass.
