Jackson Hole, Wyoming

The total solar eclipse on August 21 will be the first in almost 40 years to be visible from the continental U.S., with a path of totality that slashes across the States from Oregon to South Carolina. For prime viewing, head to Jackson Hole—spectacular scenery, expansive vistas, and minimal light pollution make it an ideal vantage point. Once the two-minute main event is over, there are plenty of warm-weather activities to keep you occupied, from hiking the backcountry of Grand Teton and Yellowstone national parks to exploring Jackson proper (be sure to snag a pastry at Persephone Bakery and a chic, locally crafted souvenir at Made). —Lila Battis
