There are two types of canyon helicopter tours: air-only and landing. Air-only flights are perfect for travelers whose time or budget is limited. They’re also ideal for folks who want to get the flavor of the canyon from a birds’-eye view. It’s about a 45-minute helicopter ride from Vegas to the West Rim (a/k/a Grand Canyon West). The route passes over Hoover Dam, Lake Mead, and the Grand Wash Cliffs. At Grand Canyon West, choppers are permitted to fly below the level of the rim and land on the canyon floor. Federal regulations prohibit this type of flight at the South Rim.
