Colorado Sightseer is a small, family run business. There were 12 adults and an older child in our group. We had a very comfortable van with large, clean windows. I was a little worried about the windy roads, but Kristen was a careful driver and the speed was such that I didn't experience any motion sickness. The stops were varied and interesting with opportunities for short hikes. Kristen is a wealth of information covering everything from local history to the ecology of each area we visited or passed through. Along the way we saw big horn sheep, mountain goats, marmots and nutria. It was truly an amazing experience. The summit of Mt Evans was the pinnacle of the trip! Do hike the last bit up to the very top, it is worth it!
