Christmas Tree Information

Perhaps the most diverse forest throughout the five-state Rocky Mountain Region and covering three million acres, we successfully blend recreation opportunities and commodity production.

Pike and San Isabel National Forests Cimarron and Comanche National Grasslands (PSICC) is a busy urban national forest noted for the majority of fourteen thousand foot peaks in Colorado and stretching from Colorado’s Front Range to the wide-open grasslands of western Kansas. Over 60 percent of the water used by metropolitan Denver originates from the South Platte River. The forest celebrates a wealth of significant experiences from historic cabin rentals to the birthplace of developed recreation on the San Carlos Ranger District. The Comanche Ranger District lays claim to the internationally known dinosaur trackway at Picket Wire Canyon and continues to excite researchers and visitors alike with new discoveries. 

With nine Wilderness areas, numerous Scenic Byways and a full spectrum of outdoor opportunities, it is no wonder that the PSICC ranks third highest in the nation for recreational visits at national forests.
