Starting three years before Grand Teton National Park was established in 1929—the Turner family ranch has been hosting visitors who come for a week of hearty meals, horseback riding, and in some cases, big game hunting at the only dude ranch in a national park. Now run by the fourth and fifth generations of Turners, it's still going strong. Accommodations are in rustic, yet comfortable, 1- to 4-bedroom log cabins, some of which date back to the late 1880s. Meals are served in the main house, where there's a welcoming family room with a fireplace and a piano, but most guests spend their free time in the saddle, exploring parts of the park only accessible via foot or hoof. Open year-round, the ranch also offers cross-country skiing and snowshoeing in the winter, and wilderness adventures, rafting, and fishing in the warmer months. For a summer stay, book at least a year (or ideally, two) in advance.
