Lake Mead National Recreation Area (NRA) follows the Colorado River from the western boundary of the Grand Canyon to just north of the city of Laughlin, NV. Between its two reservoirs, Lake Mead & Lake Mohave, there are 300 square miles of water & over 1000 miles of shoreline in the NRA. With many people flocking to the water to escape the summer heat, Hoover Dam is still the star attraction. At 726 ft high & 1244 ft in length, this engineering marvel is a must see. Lake Mead NRA is more than just a lake. The water only covers 13% of the park, leaving over a million acres of desert landscape to explore.
