Yellowstone And Grand Teton National Parks, Wyoming
These parks are so close that they almost touch, and they offer amazing autumn colors against a backdrop of snowcapped mountains, waterfalls, forests, and lakes that reflect the changing leaves. Hikes, horseback rides, and ranger-led treks are fabulous ways to see the foliage. Or get a bird's-eye view with a hot-air balloon ride or a trip on the Jackson Hole Aerial Tram.
When to Go: Head to Wyoming in September and early October to see the foliage. Read more on the Wyoming Office of Tourism website.
