Our tour guide, Marc, was exceptional. Throughout the journey he spoke about the state of Colorado. Providing detailed information on it's history, certain places to visit, querky things to do. He also provided detailed information on the Rocky Mountains, it's surrounding towns and cities, and where the best spots were. He also told us of interesting stories from accidents on the mountains to films shot here. We visited all places on the itinery with suitable time spent in each. Marc also made sure everyone was suitably comfortable, had enough supplies and generally checked on our well-being and was happy to help if needed. Personally, Marc has been the best tour guide I have come across during my time in North America and the feeling amongst fellow travellers was also the same. 10/10 for sure!
