5.00Gia and Milton were outstanding! Grand Canyon, Hoover dam, etc was wonderful. This was not a selection on the list provided to review. They provided everyone with great information, we’re patient, energetic and funny, and allowed everyone to have a phenomenal time. I would highly recommend them in any tours that they do.

3.00If you do the underground tour, there’s only about 15 min left to walk over the dam or to see exhibits. Not enough time by far. There are two brief stops on the way back to LV, again not enough time. Too rushed.
A Great Experience touring the Hoover Dam!!

5.00Had an amazing experience on this Grand Canyon tour! The itinerary was well organized, the stops were beautiful, and we got to see so much in one day. The views at Eagle Point and Guano Point were breathtaking, and the bonus stops at Hoover Dam and Hemenway Park made the trip even better. The guide and driver were friendly and kept everything running smoothly. Great value for anyone visiting Las Vegas!

A Must-Do Hoover Dam Experience

5.00My significant other and I just finished the Hoover Dam Tour with National Park Express, and we had an absolute blast! The tour was well organized, informative, and gave us plenty of time to explore and take in the incredible views. Seeing Hoover Dam up close was amazing, and we really enjoyed learning about its history and engineering. The stop in Boulder City was a nice bonus, giving us time to walk around, browse the shops, and enjoy the local atmosphere. The entire experience was stress-free, and the staff did a great job keeping everything running smoothly. We would definitely recommend this tour to anyone visiting Las Vegas who wants to get out of the city for a few hours and see one of America's most impressive landmarks. It was a highlight of our trip! 😊🏞️🚐
Could be better

3.00So we got picked up outside the horseshoe. The email is pretty clear with imagery of where the pick up is. Bus is air conditioned & relatively comfy! Robert L (the driver) was friendly enough to start & had some facts & jokes. He continued some historical facts while we were en route to the Dam. When we got there, he mentioned about tickets and we were a little confused. Turns out its a physical ticket for the plant tour. We arrive at the Dam & he parks up and lets us off. No direction, tells us a time to be back at the bus. He then said we had the option of going to a cheaper gift shop, or going to the bridge to look at the other state sign. He was like if one wants to go, we all have to go. We wanted to go. We did not go and ended up at the shop instead. Im not sure if he got confused or what, but we ended up on top of a hill. The pictures I got were amazing, I had a lovely time with my friend, but it could have been better. My issues: - We were dropped off with no direction, knowing that some of our tickets included a tour of the generator/plant. Id have liked a direction or recommendation of where to start. As such, we didnt have enough time for the tour once we realised where it was - The options of one or the other. If youve paid for a ticket and you can chose going to the top of a hill for some cheaper gifts, drinks.. or an actual tourist option. Dont have them on the same ticket or make time for both. Its not fair on a few people to not get what they paid for and wanted to do, because others dont want to do it (or the driver misunderstood!) Also, there were signs (e.g. entering nevada & arizona) that people probably want a picture of. Point that out. - Letching over younger females. I didnt like the obvious "checking out" once we were getting on the bus. It felt disgusting. I should add that Robert L did not say or physically touch this female, but the looks were creepy and uncomfortable. - Boulder City: Literally a 30 min stop with a "oh BTW, they are slow at making food here.. so hurry". It was treated as a lunch stop rather than an ability to look at the history of there - given that it housed the men who built the Dam. So it felt almost pointless.
