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 forests left in New England, with 7 acres of massive sugar maple, birch, and ash trees, some of which are more than 300 years old. There’s a nice campground with hot showers, 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.
