Questions

Hoover Dam, answered

How far is the Hoover Dam from Phoenix?

About 233 miles in a straight line from Phoenix City Hall to the dam, and about 244 from Mesa City Hall, measured to the Bureau of Reclamation's coordinates. ADOT puts US 93 from Wickenburg to the Nevada line at 200 miles. Road miles run longer than the straight line.

Can you visit the Hoover Dam for free?

The Bureau of Reclamation charges for its tours and the Visitor Center, and $10 for the Nevada-side parking garage. Lots 13 and 14 on the Arizona side are free. Walking on top of the dam is not allowed after dark.

How long does a tour of Hoover Dam take?

The Guided Dam Tour is a 10-minute movie plus about a one-hour guided tour. The Power Plant Tour's guided portion is about 30 minutes.

How much is the Hoover Dam tour?

Tour tickets are not currently available. As of October 2026, Reclamation lists Hoover Dam tour tickets as not currently available, so call 702-494-2517 before you go. When sales run, the Guided Dam Tour is $40 per person, sold on site only, first come, first served, and Reclamation says it routinely sells out. The Power Plant Tour is $25 for adults and $15 for ages 4 to 16. A self-guided Visitor Center ticket is $15. Children 3 and under are free.

Can you tour the inside of Hoover Dam?

Yes. The Guided Dam Tour goes through the historic tour tunnels and inspection tunnels, rides the original elevator to the top and includes the Power Plant Tour. The Power Plant Tour visits a platform over a 30-foot penstock and eight generators in the Nevada Powerhouse.

Is there free parking at Hoover Dam?

Yes, on the Arizona side: Lots 13 and 14 are free, and Lot 9 is $10. The Nevada-side garage by the Visitor Center is $10 per vehicle. RVs, trailers and oversized vehicles must use the Arizona-side lots.

Can cars still drive across Hoover Dam?

Yes, to reach the Arizona-side lots, after the security checkpoint on Nevada State Route 172. You cannot stop on top of the dam, even to drop off passengers. Reclamation's directions return Arizona-bound visitors through Nevada to cross on the bypass bridge.

What is the bridge in front of the Hoover Dam?

The Mike O'Callaghan-Pat Tillman Memorial Bridge, which carries the highway 900 feet above the Colorado River. It was dedicated October 14, 2010 and opened to traffic October 19, 2010.

Can you walk across the Hoover Dam bridge?

Yes, on the pedestrian walkway, during daylight only. Reclamation lists about 70 parking spaces just past the security checkpoint in Nevada.

What is special about the Hoover Dam?

Reclamation lists it at 726.4 feet from foundation rock to the roadway on the crest, with 3.25 million cubic yards of concrete in the dam itself and a nameplate capacity of about 2,080 megawatts. President Franklin D. Roosevelt dedicated it on September 30, 1935.

Is the Grand Canyon connected to Hoover Dam?

Lake Mead, the reservoir behind the dam, stretches about 110 miles up the Colorado River toward the Grand Canyon, Reclamation says.

Do you need a Lake Mead pass to visit Hoover Dam?

Reclamation's tour and Visitor Center tickets do not accept interagency passes such as America the Beautiful. The National Park Service charges a Lake Mead National Recreation Area entrance fee for recreating in the park: $25 per vehicle for up to 7 days.

Can you bring a bag into Hoover Dam?

Bags are inspected at building screening. Firearms, knives of any size, drones and marijuana are prohibited, and pets are not allowed on the dam or in the buildings, though service animals are welcome. Sealed food and bottled water may be carried.
