5.00This was our third tour with this company. Darryl only does small group tours and he does them well! Prices are very reasonable, especially for Vegas. Darryl is very knowledgeable about Nevad and Vegas and answered any questions we had. I would highly recommend any of the tours he has, you won't be disappointed! We will use Grand Adventure tours again.

5.00The tour was a great excursion from Las Vegas. Alfonso was very friendly and easygoing. He was a great tour guide, informative and very knowledgeable. He took great pictures of our group at the Las Vegas welcome sign and at the Hoover Dam. The transportation was comfortable and pick up convenient. The experience was amazing.

5.00This was my first trip to the United States, and on my bucket list I wanted to see the Hoover Dam. I booked a tour with Grand Adventures - so glad I did. Due to a couple not being able to make the tour, I had a solo tour with my awesome tour guide, Alfonso - he was so friendly, interesting and engaging and had so much knowledge about this extraordinary piece of engineering. On the tour, we visited the Las Vegas sign, amazed at the beautiful Lake Mead and historical Boulder City and took in the gorgeous landscape of Nevada before reaching the spectacular Hoover Dam. Throughout the tour, Alfonso provided a history of Las Vegas, together with interesting facts about the topography etc. Along the way, Alfonso offered to take photos which was so great - a lasting memory of the great day and the wonderful sites seen. I would highly recommend this tour. Thank you Alfonso for such a great tour.

5.00I was unable to go because my husband was ill. My friends who did go had a great time. They shared that Paul, the tour guide, was wonderful and went above and beyond to meet the needs of each individual on the tour. Traveling with a small group is the best way to see Hoover Dam.
Excellent tour

5.00My wife and I were visiting Las Vegas and we booked the Hoover dam powerplant tour. Alphonso was our guide. He was patient and very helpful. He took many pictures and was knowledgeable about many aspects of our tour! If you like history and engineering the powerplant is a fun visit. Views are amazing. Recommended 👍👍
Spectacular tour

5.00Darryl was very accommodating in the pick up as we were slightly off the strip. He was very knowledgeable and friendly. The tour was described and I would certainly recommend it to anyone traveling out to Nevada. I was amazed at the sight of the Hoover Dam and the work that went into its construction.
