About Hoover Dam

Hoover Dam is located in Boulder City, Nevada, about 30 miles southeast of Las Vegas, and is the most-visited dam in the world.

It spans the Nevada/Arizona border in the Black Canyon of the Colorado River.

Hoover Dam created Lake Mead, which is the reservoir at the bottom of the dam. 

Hoover Dam is 726.4 feet high and 1,244 feet long and is a testimony to our country’s conception and construction of such a monolithic project (after all, taming a river isn’t an easy task) especially since it was built during the Great Depression. 

Boulder City: The Town That Built Hoover Dam

The dam was built in under five years in a barren and desolate land.

It was so far from civilization that a whole settlement had to be created so that the workers and their families had a place to live while the construction workers went back and forth to the dam site.

That town is named Boulder City, and it takes its designation as “the town that built Hoover Dam” very seriously.

Everywhere you walk in the downtown historic district of Boulder City is an homage to Hoover Dam.

Hoover Dam stands as a national, historic landmark and world-renowned structure – named one of the Seven Modern Civil Engineering Wonders.

Dam's Purpose and Benefits

So why was Hoover Dam built? For several reasons, starting with the fact that the Colorado River was wreaking havoc on the land, causing catastrophic flooding.

The river needed to be controlled, and its power was used for good.

With the west becoming more and more populated, demand for a stable, year-round water supply was increasing.

The dam would also serve as a source of hydroelectric power and help to irrigate farmland.

Visiting Hoover Dam

Hoover Dam is run by the Bureau of Reclamation. Fun Fact: It doesn’t even have a physical address!

Located in Boulder City, Nevada, there are several routes that’ll get you there.

Just ask your GPS or any local from Las Vegas down on down to Boulder City. (we’re partial to the Shaka Guide tour route, ourselves!)

There are security checkpoints that you have to go through in order to get to Hoover Dam.

You’ll drive through one in your car on the way there, and then you’ll walk through one (placing your stuff on a belt just like airport security) if you choose to go inside for the exhibits or a guided tour).

But Hoover Dam is free and open to the public, so you can park and walk around the entire site (which is mostly outside) including the rim, without ever paying for a guided tour or to see the exhibits. 

INSIDER TIP If you do want to see some great, interactive exhibits, check out the free Boulder City-Hoover Dam Museum in the historic district of Boulder City (with free parking in the plaza next to it).

It’s inside the Boulder Dam Hotel and open from 7 am - 7 pm, 365 days a year. Just walk into the lobby and straight back, no fee or ticket is necessary.

Parking

There is free parking available at Hoover Dam if you drive over the dam to the Arizona side and past the lots closest to the dam.

This would require about a ¾ mile walk (or further, and uphill on the way back.)

So, if it’s a hot day, you’d have to weigh the free parking option versus the $10 parking closest to the dam on the Arizona side or the $10 parking garage on the Nevada side of the dam. (Motorhomes and other high-clearance vehicles must use the Arizona lots.)

Guided Tours

And if you do want to spend some money seeing Hoover Dam:

• $10 for the Self-Guided Visitor Center Tour (the exhibits),
• $15 for the Guided Powerplant Tour of the original construction tunnel and generators (plus exhibits), or
• $30 for the Guided Dam Tour of the tunnels and elevator to the top of the dam (plus exhibits.)

Guided Dam Tour tickets cannot be purchased online. Dam Tour Tickets are sold on-site, in person, on a first-come, first-served basis, for ages 8 and up (Student, Military, and Senior discounts with ID).

The hours of Hoover Dam are daily from 5 a.m. to 9 p.m. The tours run from 9 a.m. to 5 p.m. (The last tour departs at 3:45 pm and the doors to the Visitor Center exhibits close at 4:15 p.m.) No tours are offered on Thanksgiving or Christmas.

Getting to Hoover Dam

One of the reasons Hoover Dam gets so many visitors is that it is very close to the tourist mecca of Las Vegas.

From the city, it’s an easy, half-hour to 45-minute drive southeast to Hoover Dam (depending on the time of day, traffic, and which route you choose to get there).

The closest airport to Hoover Dam is Harry Reid International Airport (formerly named McCarran International). This airport is situated in the heart of Las Vegas.

No visit to Hoover Dam is complete without stopping by or driving down through the Lake Mead National Recreation Area afterward for some hiking, scenic driving, and overlooks.

You can also visit Boulder Beach, the shoreline of Lake Mead, which you'll see from the rim of Hoover Dam.

Stop at the Lake Mead Visitor Center for maps and advice (or take the Shaka Guide tour which is full of great suggestions)!

Visit Red Rock Canyon near Las Vegas

If you have extra time during a trip to Las Vegas or Hoover Dam, consider visiting Red Rock Canyon, located less than a half-hour west of the city.

Shaka Guide offers an incredible tour of this stunning destination!

Planning a Trip to the Grand Canyon

If you’re also planning a trip to the Grand Canyon from Hoover Dam, here’s what you need to know:

• From the Hoover Dam to the West Rim of the Grand Canyon is just under a two-hour drive. This location is actually on the grounds of the Hualapai Reservation. From there, you can walk 70 feet out over the glass Skywalk bridge for a clear view of 4,000 feet straight down to the canyon floor. (And, FYI, the road that leads to the West Rim Skywalk is not covered by all rental car companies, so check the fine print of your rental car agreement.)
• From Hoover Dam to the more popular North or South Rims of the Grand Canyon is a much further drive – about five-and-a-half hours each way to either of those rims. 
• From Hoover Dam to the East Rim of the Grand Canyon is a little under four hours.

Weather & Best Time to Visit

Since Hoover Dam is on Lake Mead, the weather is the same for both of these locations (perhaps sometimes slightly breezier when you’re walking along the top of Hoover Dam.)

You can’t go wrong with the weather at any time of year, especially when it comes to sunshine. And winters are mild, compared to many other places in the U.S.

If you had to choose a season to come, then the best time of year to visit both Hoover Dam and Lake Mead is, decidedly, in Spring.

It’s sunny yet not too hot, and therefore you’ll be comfortable hiking or walking around Lake Mead and Hoover Dam.

If you’re in it for the swimming as opposed to walking or hiking, then you’d probably like the summer when the water’s warm (85 degrees, 29C) because a dip in Lake Mead is about the only thing that could cool you off from a sweltering 110 degrees (43C) day. Let’s break it down by season (below.)

But first, if you’re looking for the best time of year to visit Hoover Dam based on tourist levels, with Hoover Dam being such a major attraction, then the least crowded time of year is January and February. And the least crowded time of day is before 10 am, or after 3 pm.

Hoover Dam in Spring

This is the most popular time to visit. With warm, sunny days (plus the bonus of spring wildflowers) hiking is in full swing!

The average high temperatures in April, May, and June are 80 - 98 degrees Fahrenheit (27-37C). Nighttime lows are 50 - 66 degrees Fahrenheit (10-19C).

Hoover Damin Summer

Record-high temperatures define summertime here. So if it’s water activities you’re looking for with the picturesque mountains surrounding you, this is the time to come.

Swimming, paddleboarding, kayaking, and boating are all popular in the summer. But you should not hike in this hot weather because it could be downright dangerous.

In fact, some hiking trails are closed down completely for public safety. The average high temperatures in July, August, and September are 89 - 103 degrees Fahrenheit (32-40C). The nighttime low averages 77 degrees Fahrenheit (25C).

Hoover Dam in the Fall

This is another great season and a very popular one for camping. The weather is warm and pleasant, and the hiking season starts back up with many trails reopening until summer rolls around again.

The average high temperatures in October, November, and December are 59 - 83 degrees Fahrenheit (15-23C). Nighttime lows are 32 - 50 degrees Fahrenheit (0-10C)

Hoover Dam in Winter

Winter sunsets are simply spectacular here, and you’ll see the occasional snow-capped mountain, too. So this is a popular season for photographers, bikers, and campers.

The average high temperatures are 57 - 69 degrees Fahrenheit (14-21C). Nighttime lows are 30 - 40 degrees Fahrenheit (-1-4C)

1. Shaka Guide Tour

There are so many places to see and things to do on a trip to Hoover Dam. This is why Shaka Guide comes so highly recommended.

The Shaka Guide Hoover Dam & Lake Mead Tour is chock full of stops, advice, and detailed information you might not ever find out about on your own. 

2. Drive Across the Dam

At Hoover Dam, you should most definitely drive across the dam before parking, and up to the Hoover Dam Lookout on the Arizona side.

Not only will this give you your best view of the dam (there is not an equal view from the Nevada side) but you’ll see where all of the free parking lots are located to help you decide where you want to park.

3. Be in Two Times Zones at Once

Once you do park, you can walk across the entire rim of Hoover Dam on both sides. On one side, looking down is Lake Mead. On the other side, looking down is the Colorado River.

Halfway across the rim is the state line, so you can stand with one foot in Nevada and one foot in Arizona, straddling two time zones (Mountain and Pacific)!

4. Guided Tours & Museums

You can also visit the cafe and gift shop, see all of the outdoor artwork, bronzes, and plaques, and use the restrooms – free of charge.

If you do want to pay, the information above has all of the details of the different ticket and guided tour options.

But if you have stopped (or plan to stop) at the free Boulder-City Hoover Dam Museum, it’s arguably as good as the exhibits at Hoover Dam.

If you're interested in exploring original tunnels and generators, along with watching a ten-minute film about the building of Hoover Dam, consider the hour-long Hoover Dam Powerplant Tour.

It includes an elevator descent, though some may find it claustrophobic.

5. Lake Mead National Recreation Area

On your way back from Hoover Dam, make sure to stop at Lake Mead National Recreation Area and Visitor Center.

This park offers stunning scenic drives, overlooks, hiking trails, and the beautiful Boulder Beach shoreline at Lake Mead.

Don't miss the Historic Railroad Hike if you're not traveling in the summer heat. It's a big part of the Shaka Guide Tour.

6. Mike O’Callaghan-Pat Tillman Memorial Bridge

On your way back from Hoover Dam, you should take a little time to walk across the Mike O’Callaghan-Pat Tillman Memorial Bridge.

It towers over Hoover Dam and gives you a remarkable view of the dam that you’d otherwise only get from a helicopter.

7. Boulder City 

On your way to or from Hoover Dam, don't miss visiting the historic district of Boulder City, where Hoover Dam is located.

Explore the charming downtown with walkable streets, lined with restaurants, shops, and hotels.

Be sure to check out the Boulder City-Hoover Dam Museum.

Beyond the historic area, Hemenway Park is like a fairytale, and you might spot bighorn sheep grazing on the green grass in the late afternoon.

8. Red Rock Canyon

If you have an extra day to spare after seeing Hoover Dam and Lake Mead, Red Rock Canyon should top your list of other stupendous places to visit.

Only about 25 minutes west of Las Vegas, it is a spectacular feast for your eyes. (Shaka Guide has a fantastic tour for that, too!)

9. Las Vegas

And, finally, let’s not forget Las Vegas – a destination in and of itself, and the place most people will fly into in order to see Hoover Dam.

The options of things to do in Las Vegas are nearly endless and ever-changing, from:

• gaming (for those 21+) to shows
• fine dining to hotel experiences
• museums (like the Mob Museum and Neon Museum) to iconic wedding chapels, and
• the Fremont Street Experience to the Stratosphere observation deck now called the Strat Skypod

Some other activities include: 

• Biking: River Mountains Loop Trail Bike Rentals: All Mountain in Boulder City
• Hiking: The Historic Railroad Trail, Owl Canyon, Northshore Summit & more
• Swimming
• Camping
• Fishing
• Guided Fishing Trips: Captain Jack’s at Boulder Harbor Lake Mead
• Lake Mead Riverboat Cruises
• Kayak Tours of Lake Mead: Blazin’ Paddles, Boulder City
• Stand-Up Paddleboard (SUP) Rentals for Lake Mead: Paddle to the Core, Boulder City
• Boat/Jet Ski Rentals for Lake Mead: Boating Lake Mead at the Lake Mead Marina

Where To Stay

Best Western Hoover Dam / Photo by Lizzie Gerecitano

If you choose to stay closer to the Hoover Dam itself, and not in nearby Vegas, there are a few options for you: 

Best Western Hoover Dam

This is a great place in the heart of the Boulder City Historic District, with free parking and a pool.

Reasonably priced. Leave your car there and stroll through this gorgeous little town’s shops and cafes.

The hotel has a nice pub/restaurant on the premises with outdoor seating, and ask about a voucher for breakfast across the street at the fabulous Southwest Diner!

Boulder Dam Hotel

This is a gorgeous, classic, and quaint hotel featuring the incredible Boulder City-Hoover Dam Museum in the lobby.

Their outdoor patio is in the heart of the historic district, so you can walk to shops and restaurants. This hotel sells out, so advanced reservations are necessary.

The Hoover Dam Lodge

This hotel is on the highway in Boulder City (instead of in the walkable, downtown historic district) and features a trail that leads down onto the Historic Railroad Hike in Lake Mead’s National Recreation Area. 

Water Levels - What You Need to Know

Due to climate change, ongoing drought, and more people needing water from the area served by Hoover Dam, Lake Mead has dropped below important levels in recent years.

As environmentalists continue to search for ways to refill the lake, our nation’s largest reservoir continues to drop in water level. 

Lake Mead provides water to about 25 million people in Arizona, Nevada, California, and parts of Mexico, and provides electricity to 1.3 million homes as well, in the form of hydroelectric power.

If Lake Mead's water levels can't go up, the southwest will experience severe water cuts.

These will start with farms and then affect cities, reducing the amount of Colorado River water available.

Hoover Dam and Glen Canyon Dam at Lake Powell are using more water than the Colorado River can provide.

Changes are needed, or the Colorado River might start to dry up and not flow past Hoover Dam.

You can find out more details about this and many other geological and scientific facts about Lake Mead and Hoover Dam by downloading the Shaka Guide tour of Hoover Dam & Lake Mead.

It does a really good job of explaining the challenges that enormous, man-made dams like this face.
