A half-day trip from Las Vegas to Hoover Dam, 726 feet of 1930s concrete on the Nevada–Arizona line, with the Visitor Center, power plant tour options and the view from the bypass bridge.
Hoover Dam is the reason modern Las Vegas exists. Built between 1931 and 1936 in Black Canyon on the Colorado River, the 726-foot curved concrete dam created Lake Mead and still generates hydroelectric power for Nevada, Arizona and California. It is about 35 miles southeast of the Strip, roughly 45 minutes by car through Boulder City. That makes it the easiest major day trip from Las Vegas: you can be there and back in half a day.
The Bureau of Reclamation runs three ways to see it. The Visitor Center ticket covers the exhibits, a film and the overlook. The Power Plant Tour adds a guided trip down by elevator to see the generators, and you can book it online. The Guided Dam Tour is the longest and most detailed, going deeper inside the structure.
It is sold only on site, first come, first served. The site is open daily from 9am to 5pm. Whichever you choose, you can walk across the top of the dam, where the Nevada–Arizona line is marked, and see the art deco details and the memorial to the workers.
Day tours from Las Vegas handle hotel pickup and transport, and usually include a Visitor Center or Power Plant Tour ticket, or time to explore on your own. Some add a stop at the Mike O'Callaghan–Pat Tillman Memorial Bridge. Its walkway gives the classic view of the whole dam from about 900 feet above the river. Others combine the dam with Lake Mead, Boulder City or a Grand Canyon West day. Check what your tour includes, because time inside the dam varies a lot between products.
A few practical points. All visitors go through security screening, and large bags are not allowed in the facility. Summer temperatures in Black Canyon are intense, and the top of the dam has little shade, so go early. The Dam Tour involves stairs and narrow passages and is not suitable for everyone. Arizona does not observe daylight saving time, so in summer the clocks on the two ends of the dam differ by an hour. Tours run on Nevada time.
What to expect
The experience
The Visitor Center ticket ($15) covers exhibits, a film and the overlook. The Power Plant Tour ($25 for adults) is a guided visit to the generators and can be booked online. The Guided Dam Tour ($40) goes deeper into the structure and is sold only on site, first come, first served.
Best time
Arrive early to beat the crowds and heat; the bypass bridge is best for photos in good light.
How long
About four to five hours.
Tips
You can walk across the top of the dam for free. Look out for the state-line markers, the art deco towers and the memorial to the workers who built it. It is exposed and hot in summer. The Mike O'Callaghan–Pat Tillman Memorial Bridge has a pedestrian walkway with the best full view of the dam, about 900 feet above the river. Many tours include a stop there, and it is a short uphill walk from its parking area. Everyone is screened, and large bags are not allowed inside the facility. Leave them on the coach or in your car and carry only essentials. Tours from Las Vegas include hotel pickup and usually a Visitor Center or Power Plant Tour ticket. Some combine the dam with Lake Mead, Boulder City or the Grand Canyon. Check how long you will spend at the dam. Arrive early and buy the Guided Dam Tour on site if you want the most in-depth visit. It is not sold online. Make sure your trip includes the bypass bridge walkway for the classic photo of the whole dam. Add Boulder City's historic downtown or a Lake Mead cruise to turn it into a full day.
