The bus eases out of Las Vegas before dawn and the desert stretches open: rust-colored ridges, a low sun, and the Colorado River threading the canyon like a bright vein daring you to follow it. In a small group, the tour moves with purpose — a photo stop at the 'Welcome to Fabulous Las Vegas' sign, a breakfast pause in Boulder City, then the slow reveal of Hoover Dam rising from the canyon floor.

Sun Protection for Overlooks
The bridge and Lake Mead viewpoints are exposed; wear sunscreen and a wide-brim hat even on cool days.

Stairs and uneven surfaces in the power plant and on the dam make sturdy closed-toe shoes a practical choice.
