I recently visited Colorado with my two young kids, ages 4 1/2 and 6. When I travel, I try to find fun activities we can do as a family, all the while experiencing local flavor. We decided to do a couple of easy hikes so that we could all enjoy the beautiful outdoors that the state of Colorado has to offer. Two hikes recommended for youngsters by the NPS in Rocky Mountain National Park are Sprague Lake and Bear Lake. We did each of these hikes on separate days.
