Yosemite National Park
Yosemite National Park is one of the most visited of the national parks and considered to be one of the top rock-climbing destinations in the world. In 1984, it was designated as a World Heritage Site by the United Nations for its natural beauty and ecological diversity. It's also famous for the dense concentration of waterfalls, including Yosemite Falls, the highest in North America at 2,425 feet. There is no shortage of outdoor adventures to be had at Yosemite and campers can find options aplenty in the valley. Those who are less into roughing it can shack up at any one of the more luxe hotels and resorts like the Tenaya Lodge at Yosemite.
