With this year marking the centennial of the National Park Service, there's no better time to explore a national park, whether it be close to home or across the country. Better yet, make it a camping trip so you and the kids can fully immerse yourselves in the adventure of it all. If you need help narrowing it down, Glacier National Park in Montana or Yellowstone National Park in Wyoming definitely won't disappoint, says Bryanna Royal of Crazy Family Adventure who has been traveling the country full-time with her husband, four kids and two dogs in their RV since May 2014. "The beauty of Glacier is simply breathtaking," she says. "I guarantee that your kids will not soon forget their experience in Glacier National Park and may go home with a new dream to be a Park Ranger, outdoor enthusiast and with an overall love for the beauty of our world." Plus, it has incredible wildlife sightings, including mama bears and their cubs, moose and big horn sheep, she notes. Yellowstone, however, is equally as breathtaking with its hot springs and colorful layered rock formations. It, too, has plenty of wildlife to spot—from bears to buffalo.
