Located in the southeast corner of Nevada, Clark County offers everything from outdoor family activities to adult excursions and events. Thousands of people are attracted to this area as it is home to Las Vegas, which is famous for its neon-illuminated casinos, world-class performances, unique nightclubs and NASCAR races at the Las Vegas Motor Speedway. From the bright lights of Vegas, visitors can head to the Hoover Dam, a wonder of a different sort. Rising 726 ft (221 m), the dam is a source of electrical power, as well as a water management facility and an engineering marvel that offers presentations, exhibitions and guided tours. Thousands of ancient cave drawings are found at Grapevine Canyon, which also boasts waterfalls and trails for visitors to explore. Clark County is also home to Red Rock Canyon National Conservation Area and Valley of Fire State Park, as well as the tourist destinations of Henderson, Laughlin and Boulder City.
