I don't know how to express my experience with Grand Adventure. I am SPEACHLESS!! We took West Rim Skywalk tour and our tour guide was Erik. He was AWESOME. He was very knowledgeable about history of cities, Hoover Dam, Grand Canyon, plants, best shooting points of pictures, everything. Also, he was super friendly. The tour cost included breakfast, lunch and plenty of water. I will have South Rim Tour next time and will request Eric as my tour guide.
