Yellowstone National Park, WY
America’s first national park should be a bucket list entry for everyone. In addition to its nearly three million majestic acres, it’s to more than half the world’s hydrothermal features like geysers and hot springs. But it’s also home to the most thrilling and extensive collection of wildlife in the continental U.S.: From Grizzlies and brown bears to elk and deer and bison and mountain lions and now even 300-plus wolves. There’s truly nothing like it. There’s more than 2,000 camp sites across several campgrounds, but our pick is the option to go backcountry. You’ll need to get a permit and spots are limited (though you can reserve ahead of time) and be sure to follow best practices for camping and hiking in bear country. And remember to stifle the urge to mingle with the bison herds – way more people are injured by them every year than ever have encounters with bears.
