1. Stanley, ID
In September and early October, Idaho's jagged Sawtooth Mountains become a vibrant, technicolor dreamland. Camp out beneath the changing cottonwood, aspen, and alder trees at Stanley RV + Camp (just outside the tiny town of the same name) where there are full RV hookups, spots for tent camping, and two charming no-frills A-frame cabins. Better yet? You'll find whistle-clean restrooms, laundry facilities, and a postcard-perfect river right across the street. For a more rustic night out, try the shores of Pettit Lake where the alpine views are breathtaking and the popular Alice Lake Loop starts right outside your door.
