My husband and I decided to take the Mountain Summit shore excursion (bus tour) because we had already done the train in the past. The road tour is on the opposite side of the canyon from the tracks, so offers a different perspective than from the train. We could see the train on the other side and passed it. The scenery was fantastic, and due to the exceptional weather, our driver/guide (Bryan Terrell) took us a little farther than he is usually able to do. He went above and beyond, making our excursion very enjoyable. He was very knowledgeable and humorous. He made many stops so we could get good pictures of all those beautiful snowy peaks, and never rushed us along. We saw a bear and he stopped a safe distance away so we could view it. The whole tour was a very reasonable price, and provided excellent value. Thank you Bryan for a great tour! We highly recommend this tour.
