With 653 acres, Green River Reservoir is the largest “quiet” lake in Vermont. No gas-powered boats are allowed on the water, which makes it perfect for paddling. And you need a boat — and some muscle — to get to every one of the 28 remote campsites tucked in along the 19 miles of undeveloped shoreline; Some spots are as far as two miles from the launch. Parking is limited, and the park is considered “full” when the lot is.
