3. Yellowstone National Park
Nothing can bring a family together or make mom and dad feel like kids again quite like camping under the stars and snuggling up by the campfire with s’mores. And there is no better place to do it than Yellowstone National Park, which boasts over 2.2 million acres of outdoor beauty. There is something for everyone here—hiking, biking, fishing, boating, horseback riding and more. Or you could just choose to relax and observe the wildlife (elk, buffalo and even grizzlies) and nature attractions (think geysers, canyons, and waterfalls).
