1. Yosemite National Park | CA
Millions of people come to Yosemite National Park each year to see jagged peaks, glaciers, lush meadows and some of the world’s tallest waterfalls. Spanning 1,200 square miles, Yosemite offers activities ranging from child-friendly to extreme. Massive granite slopes like Half Dome and El Capitan dominate the landscape, taunting rock climbers. Paddlers dip into lakes and rivers, drivers cruise the dramatic Tioga Road, and day hikers walk by sequoias and canyons. Backpackers take to the rugged John Muir trail, named for the writer who helped create the park in 1890.
