To preserve the high-elevation ecosystems and wilderness characters of the southern Rocky Mountains within its borders and to provide the freest recreational use of and access to the park's scenic beauties, wildlife, natural features and processes, and cultural objects.
- Rocky Mountain National Park provides exceptional access to wild places for visitors to recreate and experience solitude and outstanding scenic beauty. Trail Ridge Road, the highest continuous paved road in the United States, and the park’s extensive trail system bring visitors to the doorstep of a variety of wilderness-based recreational opportunities.
- Fragile alpine tundra encompasses one-third of Rocky Mountain National Park, one of the largest examples of alpine tundra ecosystems protected in the contiguous United States.
- Glaciers and flowing fresh water carved the landscapes of Rocky Mountain National Park. The park is the source of several river systems, including the Colorado River and the Cache la Poudre, Colorado’s first and only designated wild and scenic river.
- The dramatic elevation range within the park boundary, which spans from 7,600 feet to 14,259 feet and straddles the Continental Divide, allows for diverse terrestrial and aquatic ecosystems, varied plant and animal communities and a variety of ecological processes. The park is designated as a United Nations Educational, Scientific, and Cultural (UNESCO) international biosphere reserve and globally important bird area, with portions of the park’s montane, subalpine, and alpine ecosystems managed as research natural areas for scientific and educational purposes.
- The mountainous landscape of Rocky Mountain National Park has drawn people to the area for thousands of years. Visitors can see remnants of the different ways people have used this land over time, ranging from prehistoric big game drives to dude ranching to recreational tourism.
