The High Sierra is a beautiful and unspoiled paradise that is a total contrast to the beaches and heat of Southern California. Frequented by lovers of the outdoors, the area boasts the world-renowned Yosemite National Park, which rivals other famous mountain parks in North America for its sheer beauty. King's Canyon and Sequoia national parks are also within the High Sierra, both of which contain rare natural treasures, such as Crystal Caves, Grant Grove and Cedar Grove Village. Those looking for an adrenaline rush can embark on a white-water rafting trip on one of the many rivers in the area. During the 1800s, the High Sierra was in the midst of the Gold Rush. While those days are long gone, many historic sites remain for travelers to visit, including Hangtown's Gold Bug Mine in Placerville and Marshall Gold Discovery State Historic Park in Coloma.
