My husband and I took the West Rim/Skywalk tour on August 2nd and would highly recommend it! Our tour guide Erik was extremely knowledgeable and very friendly! He was able to talk about the little towns we passed through, the different animals we encountered, the different plants, the history of Hoover Dam and the Grand Canyon itself and also gave us pointers on how to take the best pictures. He also helped the group take many awesome pictures. Thanks again, Erik for making this trip a truly remarkable experience!
