Visiting Hoover Dam from Las Vegas is one of the easiest “big wow” day trips in Nevada: a world-famous engineering landmark on the Nevada–Arizona border, stunning desert views, and a visitor center with tours that take you inside the dam’s tunnels and powerhouse. This guide is built for real trip planning—hours, ticket prices, security rules, exact driving directions, and airport connections—so you don’t waste time once you arrive.
📍 What is Hoover Dam (and what to expect)
Hoover Dam is a massive concrete arch-gravity dam on the Colorado River, creating Lake Mead and generating hydroelectric power. For visitors, the experience usually includes:
- 🚶 Walking the top of the dam (outdoor views of Lake Mead on one side and the Colorado River on the other)
- 🏛️ Visiting the Visitor Center exhibits + observation deck
- ⚡ Taking a guided tour into the powerplant (and, if available, deeper “Dam Tour” access)
Good to know: Hoover Dam is open to the public daily 5:00 a.m. to 9:00 p.m. (Pacific Time).

Pro tip: If your goal is the Visitor Center + tours, the Nevada garage is usually the most convenient.
🚗 How to get to Hoover Dam from Las Vegas (step-by-step)
Hoover Dam is about 30 miles southeast of Las Vegas.
Fastest drive (most common route)
- Get onto I-11 S / US-93 S / US-95 S toward Boulder City
- Take Exit 2
- At the traffic circle, take the 3rd exit onto NV-172
- Turn right onto NV SR-172 / Hoover Dam Access Rd
- Follow signs to parking/tours
⏱️ Typical drive time is often around 35–45 minutes depending on traffic/lines at the checkpoint (holiday peaks can be slower). The Bureau of Reclamation specifically warns about periodic delays, especially in summer/holidays.
✈️ Airport Connections (Harry Reid International Airport — LAS)
If you’re landing at LAS and going straight to Hoover Dam:
✅ Option A: Rental car (most reliable)
- Pick up your car at LAS rental facilities, then route yourself to I-215 E → I-11/US-93 S, then follow the official Exit 2 → NV-172 directions above.
Why it’s best: you control timing (tours sell out), and returning is stress-free.
✅ Option B: Taxi / rideshare (works, but plan your return)
- You can get dropped near the Visitor Center area; however, because the dam area is busy and pickup availability can vary, arrange a clear pickup plan/time window before you go.
✅ Option C: Tour bus (no driving, easiest “hands-off” day trip)
Travel Nevada recommends bus tours from Las Vegas (many pick up on the Strip), often combining Hoover Dam + Boulder City.
🚌 Can you do Hoover Dam without a car?
You can, but it’s not as simple as a single city bus that drops you at the Visitor Center.
Practical car-free strategies:
- ✅ Book a Hoover Dam tour bus from Las Vegas (simplest)
- ✅ Take a bus to Boulder City (for example, intercity services exist) and then use a taxi/rideshare onward to the dam
- ✅ Use a private shuttle between Las Vegas and Boulder City, then connect onward
🎟️ Which tour should you pick?
If you want the “full inside the dam” experience
- Guided Dam Tour ($40)
Arrive early because it’s on-site only and can sell out.
If you want “inside + wow” but with more availability
- Guided Power Plant Tour ($25 adult / $15 youth)
The official site notes the least busy windows are 9:00–11:00 a.m. and 2:30–3:45 p.m.
If you mainly want views + history + photos
- Visitor Center ($15) + outdoor walking time
📸 Best viewpoints (quick wins)
1) Top of the dam (classic view)
Great for wide shots and the iconic “standing on the border” feeling.
2) Hoover Dam Bypass Bridge viewpoint
For the dramatic “dam from above” look, stop at the Mike O’Callaghan–Pat Tillman Memorial Bridge area—known for bird’s-eye perspectives of the dam.
⚠️ Common mistakes (and how to avoid them)
- ⚠️ Showing up late and missing tours: Last tour departs about 4:10 p.m. and doors close 4:15 p.m.
- ⚠️ Bringing a pocketknife “by accident”: knives of any size are not allowed in buildings.
- ⚠️ Underestimating checkpoint delays: plan buffer time; delays are common in peak periods.
- ⚠️ Trying to stop on the dam to drop someone off: stopping/loading/unloading on top is prohibited—use parking lots.
- ⚠️ Thinking national park passes work here: they aren’t accepted for tours/Visitor Center.
♿ Accessibility notes
- Power Plant Tour is listed as accessible to wheelchairs/motorized scooters/strollers.
- Wheelchairs are available to rent at the parking garage for $5.
- Dam Tour has restrictions (example: no motorized wheelchairs; ventilation shaft not accessible to manual wheelchairs).
