Rocky Mountain National Park spans 265,769 acres of pristine wilderness (358 square miles), making it one of the largest national parks in the United States.

• Trail Ridge Road (which connects Grand Lake and Estes Park) opened in July 1932.
• Approximately 11 miles of the drive along Trail Ridge Road are above timberline.
• Because Trail Ridge Road climbs to an elevation of 12,183 feet, it’s one of the most spectacular places in the world to star gaze. Go into Rocky Mountain National Park at night (the park is open 24/7), drive to a high point, and settle in for some spectacular celestial viewing!
• Trail Ridge Road has a relatively gentle grade, never exceeding 7%, and typically less than 5%.
• Inside Rocky Mountain National Park, there are 5 campgrounds, with 585 campsites.
• Before 1978, there were very few moose in Rocky Mountain National Park. In 1978 and 1979, 24 moose were relocated from Wyoming, and by 1994, the herd had grown to 700 moose. Today, most of the moose in Rocky Mountain National Park are on the western side, in and near Grand Lake.
• There are 600 buildings inside Rocky Mountain National Park, 150 of which are historic structures.
• Rocky Mountain National Park averages around 3 million visitors a year.
• The park contains 5 different visitor centers, as well as the Holzwarth Historic Site and the Sheep Lakes Information Station.
• Hundreds of species of animals inhabit the park, including moose, elk, deer, bighorn sheep, cougar, bear, fox, bobcat, marmot, beaver, porcupine, and badger, among others. Several species of fish, including 4 different species of trout, inhabit the park’s lakes and streams.
• Some 282 species of birds have been reported to inhabit or visit the area since the designation of Rocky Mountain National Park in 1915.
• Roughly 355 miles of trails are maintained for hiking within Rocky Mountain National Park.
• The park contains 450 miles of streams and 156 lakes. Only 48 of the 156 lakes contain trout populations, as cold water temperatures and lack of spawning habitat prevent populations from sustaining in many of the higher elevation lakes.
• Longs Peak is the tallest mountain in the park, with peak elevation of 14, 259 feet.
