Cruise boats plying Lake Mead and the Colorado River offer daytime sightseeing tours, evening dinner cruises and opportunities for celebrating special events. The Desert Princess on Lake Mead above Hoover Dam and the Celebration on the Colorado at Laughlin are jaunty replica paddle-wheelers reminiscent of Mississippi River steamboats. The USS Riverside is a sleek modern cruiser built to motor upstream from Laughlin under the highway bridge toward Davis Dam.
