The dam deck is free and open until 9 p.m., but the Visitor Center doors close at 4:15 p.m. and the last paid tour leaves at 4:10 p.m. (1). If a Hoover Dam tour is the reason you’re driving out from the Las Vegas Strip, plan backward from 4:10 p.m. Then choose between the Power Plant Tour, the Guided Dam Tour, or the free deck and bypass bridge alone.
✓ Pros
- Interior access connects the dam's scale to the machinery that operates it.
- Free public areas make it possible to visit without committing to an interior tour.
- The bypass bridge offers a viewpoint of the dam that the deck cannot provide.
✗ Cons
- The last tour departure leaves little room for a late arrival or a slow security line.
- The most complete tour cannot be booked online and may sell out.
- Exposed walking routes are a poor fit for hot afternoons or visitors needing shade.
Hoover Dam Tour Options: Power Plant vs Guided Dam Tour
The Bureau of Reclamation runs three paid options at Hoover Dam: the Guided Power Plant Tour, the Guided Dam Tour, and the Self-Guided Visitor Center Tour. The Bureau sells the Guided Dam Tour as an extended package, and the other two tickets can be upgraded on-site (1). The Self-Guided Visitor Center Tour includes narrated exhibits, the 3D regional dam model in the Original Exhibit Building, and an observation deck with a 360-degree view of the dam, Colorado River, Lake Mead and the bypass bridge (1).
As of November 2026, Hoover Dam tours cost $15 per person for the Self-Guided Visitor Center Tour, $25 for adults on the Guided Power Plant Tour, and $40 per person for the Guided Dam Tour.
What the Guided Power Plant Tour Covers
The Power Plant Tour walks you through original construction tunnels to a platform above a 30-foot-diameter (9 m) penstock, then on to 8 commercial generators in the Nevada Powerhouse (1). It is the only guided tour listed as accessible to wheelchairs, motorized scooters and strollers (1). If anyone in your group uses one, this is your tour.
What the Guided Dam Tour Adds
The Guided Dam Tour ($40 per person, against $25 for an adult Power Plant ticket) is the extended package: historic tour tunnels, a ride in the original elevator to the top of the dam, a walk through the inspection tunnels at the dam’s center, and a look at the Colorado River through an inspection ventilation shaft (1). The route includes elevators and confined spaces. Strollers and motorized wheelchairs are not allowed, and the ventilation shaft is not accessible to manual wheelchairs (1). If you have specific access needs, confirm them with the Bureau before you go.

Buying Tickets Online vs On-Site: What You Need to Know
You can buy Power Plant and Visitor Center tickets online through the Bureau’s ticket link. Guided Dam Tour tickets are sold only in person, first come, first served (1). Your entire group must be present to buy them, everyone clears security before reaching the counter, and these tours routinely sell out (1). The Bureau accepts major cards and cash, but not personal checks (1).
As of November 9, 2026, the Bureau’s tour page lists all three tours with no service notice, but it warns that tours can be cancelled without prior notice, with refunds (1). If the Guided Dam Tour and its original elevator are the reason for your trip, call the Visitor Center on 702-494-2517 before you drive out (1).
The Visitor Center and tours run 9 a.m. to 5 p.m. daily, except Thanksgiving and Christmas Day (1). That 5 p.m. figure is the trap. Doors close at 4:15 p.m. and the last tour departs at 4:10 p.m. (1), so a 4 p.m. arrival leaves you almost no margin once you’ve parked and cleared screening.
The Bureau lists 9-11 a.m. and 2:30-3:45 p.m. as the least busy windows for Power Plant Tours (1). If you want Guided Dam Tour tickets, the morning window is the one to target. Arriving at opening gives you the best chance at seats and the lightest crowds. The afternoon window works for the Power Plant Tour if you already hold online tickets.
Security Screening and What You Can’t Bring Inside
Every visitor entering the Hoover Dam Visitor Center goes through screening. You remove metal objects, get screened with a hand-held wand (or ask for a pat-down instead), and have your belongings inspected (1). Bottled water is allowed. Sealed food and drinks can come in, but you can’t eat or drink them inside the buildings (1). The Bureau’s group-visit guidelines recommend bringing water, in a container that is not glass (2).
Leave these behind:
- Weapons and knives (banned from dam buildings)
- Firearms, explosives, fireworks, drones and marijuana (banned on all dam property) (1)
- Pets and comfort animals, which are not allowed on the dam or in buildings; service animals trained to aid a person with a disability are welcome (1)
Animals also cannot be left unattended in vehicles (1), so a pet in the car means someone stays with it.
Getting to Hoover Dam from Las Vegas: Driving and Parking
Getting to Hoover Dam from Las Vegas means a drive of about 30 miles southeast: take I-11/US-93 through Boulder City to Exit 2, then follow Hoover Dam Access Road (NV-172) (6). The Nevada-side parking garage near the Visitor Center costs $10 per vehicle (1). Oversized vehicles, recreational vehicles and vehicles with trailers must park on the Arizona side, in Lot 9 ($10) or Lots 13 and 14 (no charge) (1). Choose the garage if you’re touring, since it puts you closest to the Visitor Center and the security entrance.
Most passenger vehicles can still drive across the dam. All of them are subject to inspection on the Nevada side, and drivers who decline inspection cannot proceed (1). Stopping on the dam to pick up or drop off passengers is prohibited (1), so plan to park, not to drop someone at the door.
A good portion of the visit is outdoors, and the Bureau asks visitors to plan for all types of weather (1). Spring and late fall make the walking portions far more comfortable than midsummer afternoons.
The Hoover Dam Bypass Bridge Walk: Views You Won’t Get From the Dam
The Hoover Dam bypass bridge walk on the Mike O’Callaghan-Pat Tillman Memorial Bridge is free and gives you a bird’s-eye view of the dam (7). Drivers crossing the bridge cannot see the dam; the pedestrian walkway is where you get that angle (8). The Visitor Center observation deck looks out at the bridge (2), but walking onto the bridge flips the view: the dam and the Colorado River canyon line up below you.
A parking area on the Nevada side serves the bridge, and stairs and ramps lead up to the walkway (8). Expect sun exposure and wind across the span. Bring water and a hat in warm months.
If you’re short on time, rank this above the Self-Guided Visitor Center Tour. It is free (7), and it shows the dam from an angle no tour ticket gives you.
Combining Hoover Dam with Lake Mead National Recreation Area
Lake Mead National Recreation Area charges its own recreational-use pass, separate from any Hoover Dam ticket. As of November 2026, a private non-commercial vehicle pays $25 for 1-7 days of access (5). That single pass covers everyone in the car (5).
Lake Mead has been cashless since January 1, 2024 (5). Entrance stations accept only electronic card payments, so bring a card even if you paid cash at the dam. If you carry the America the Beautiful pass for national parks, leave it in the car here: Hoover Dam does not accept it for tours or the Visitor Center (1). The reverse also holds: your dam tickets do nothing at the park entrance.
For a couple doing the Guided Dam Tour and then driving to the lake, budget three separate charges (prices as of November 2026):
- $40 per person for the Guided Dam Tour (1)
- $10 for the Nevada-side garage (1)
- $25 for the Lake Mead vehicle pass (5)
Do the dam first, while tour seats are available, and save the lake for the afternoon.
Visiting the Dam Without a Tour: Free Public Access
You can visit Hoover Dam without buying a tour. The dam is open to the public daily from 5 a.m. to 9 p.m., separate from the paid Visitor Center and tours that run 9 a.m. to 5 p.m. (1). Walking across the deck, crossing the Nevada-Arizona line and looking down the downstream face cost nothing beyond parking.
The difference is depth. Public access shows you the dam’s outside. Only the paid tours take you into the construction tunnels, past the penstock and into the powerhouse (1). If you’re on a tight schedule or arriving after 4:10 p.m., the free deck plus the bypass bridge walk is a complete visit.

- Is it worth doing a tour at the Hoover Dam?
- Choose an interior tour when seeing the operating infrastructure matters to you; the public areas and bridge walk are enough for an exterior-focused visit.
- Which is the best tour of the Hoover Dam?
- The Guided Dam Tour covers the most interior ground, while the Power Plant Tour is the practical choice when accessibility or a shorter visit matters.
- Can I visit Hoover Dam without a tour?
- Yes. You can visit the public dam deck and bypass bridge without booking an interior tour; those areas provide an exterior visit rather than access to the machinery.
- How much does it cost for a tour of the Hoover Dam?
- As of November 2026, paid options range from $15 for the Visitor Center to $40 per person for the Guided Dam Tour.
- Are Hoover Dam tours wheelchair accessible?
- The Power Plant Tour is the listed accessible guided option; contact the Bureau about individual access needs before choosing a route.
- Can you still drive over Hoover Dam?
- Most passenger vehicles can cross, but drivers must accept Nevada-side inspection and cannot use the dam as a passenger pickup or drop-off point.
- Can I buy Guided Dam Tour tickets online?
- No. Buy those tickets in person with every member of your group present; online purchase is available for the other paid tour options.
- Where can I park at Hoover Dam and how much does it cost?
- The Nevada-side garage near the Visitor Center costs $10 per vehicle. Oversized vehicles, RVs and vehicles with trailers park on the Arizona side, in Lot 9 ($10) or Lots 13 and 14 (no charge).
Planning Your Hoover Dam Day
The decision rule is simple:
- Guided Power Plant Tour: pick this if you need step-free access or want a lighter commitment you can book online.
- Guided Dam Tour: pick this for depth, but only if you can reach the ticket counter early in the morning with your whole group.
- Free public access: pick this if the views matter more than the interior. Walk the deck and add the bypass bridge.
Whichever you choose, arrive well before the 4:10 p.m. last tour and the 4:15 p.m. door closure (1). Carry a payment card if Lake Mead is on the afternoon plan, since the park takes no cash (5).
