This was a great tour of Denver, Boulder, Estes Park, and the Rocky Mountain National Park. This was our first (and probably only) trip to Colorado, and it was great spending the day with Christin and getting to learn about the area as well as the majestic Rockies! The tour is small enough (about 12 of us) to have that intimate feeling and enjoy the camaraderie of fellow passengers. Christin provided snacks and water as well as traction grip cleats for our shoes in the snowy/icy areas. She often volunteered to take pictures of tour members and scenery. She knows the area well and is quick to spot wildlife. We had a beautiful day for the tour, and the recent snow made the mountains even more beautiful. I would highly recommend this tour, or check out the other tours Colorado Sightseer offers in the Denver area. This was definitely a highlight of our multi-state vacation! Thanks, Christin!!!
