My sister and nieces came to visit us last week. We took them up to Estes Park and Rocky Mountain National Park on Saturday and had the best time. We took the Aerial Tramway to the top of Prospect Mountain for some wonderful views and to feed the chipmunks. The kids could have stayed here all day! We then took them to Rocky Mountain National Park, to go boulder climbing at the Alluvial Fan. It was just a perfect day in every way!
