Establishment the Rocky Mountain National Park

President Woodrow Wilson signed legislation on 26 Jan 1915 to create Rocky Mountain National Park. In 1976 the natural ecosystems of the park, which represent the Rocky Mountain Biogeographic Province, received recognition through the United Nations “Man and Biosphere” program as an international Biosphere Reserve. The reserve is part of the network of protected samples of the world’s major ecosystem types that is devoted to conservation of nature and genetic material and to scientific research in the service of humanity. It provides a standard against which the effects of human impact on the environment can be measured.

Size and Visitation of Rocky Mountain National Park

Acerage – FY 2001
Gross Area Acres 265,769

The park has grown to more than 415 square miles. In 1990, it gained an additional 465 acres when Congress approved expansion of the park to include the area known as Lily Lake. The National Park Service, the Conservation Fund, and some diligent legislators successfully halted land development in this area adjacent to the park’s boundary. It now is an important buffer zone that helps protect the migratory routes of wildlife in the park.

History of Rocky Mountain National Park

The snow-mantled peaks of Rocky Mountain National Park rise above verdant subalpine valleys and glistening lakes. One-third of the park is above tree line, and here tundra predominates – a major reason why these peaks and valleys have been set aside as a national park.

Visitors Guide


Park Headquarters, Lily Lake, Moraine Park Museum, Alpine Visitor Center and Kawuneeche Visitor Centers are accessible with some ranger led activities. Trail to Bear Lake, Beaver Boardwalk, Sprague Lake and Coyote Valley trails are accessible, as well as the backcountry site located at Sprague Lake. Most campgrounds, amphitheaters, overlooks and bathrooms are moderately accessible.

Summer backcountry campsites can be reserved starting 01 March each year. Permits are required for all overnight camping. They may be obtained at the Headquarters Backcountry Office or the Kawuneeche Visitor Center. Self reservation is available in some locations through out the winter months. Winter backcountry hours are 8:00 am – 4:30 pm.

Basic Recommendations

I recommend that you plan your trip and the areas you would like to see and then go and relax and make a day of it. Go and see all that is in the area and enjoy it. You spend more quality time and learn and see more than you could ever imagine.

Rocky Mountain National Park is open year-round with peak visitation in Jul and Aug. The roads close after heavy snow and the only road that goes through the park from one side to the other, closes from Oct through May.

Biking Guide

Biking in Rocky Mountain National Park is for the serious tourer. Riding is on paved road; bouncing downhill over bouldered trail is strictly prohibited. But don’t think the challenge is any the less for that. Trail Ridge Road is a 4 to 6 hour ride. If you can climb the 3700 feet up from Estes Park, you will find a delightful Alpine ride at 12,000 feet. And of course it’s all downhill from there, 3400 feet to Grand Lake!

Sport fishing is permitted in Rocky Mountain National Park, a protected area. Fishing activities are balanced with efforts to restore and perpetuate n atural aquatic environments and life.

Fishing was popular with early settlers in the Rocky Mountains. In an attempt to improve the sport, they stocked many streams with non-native species of trout and moved trout to lakes and streams that lacked them. The only trout native to the park were the greenback cutthroat and the Colorado River cutthroat.

Food and Supplies

Available in towns of Grand Lake or Estes Park and snack bar located at gift shop at Fall River Pass.


There are 355 miles of trails ranging from easy to strenuous. There are 82 miles of paved roads, and 28 miles of unpaved roads.

Fall River Road, one-way uphill only, is nine miles of gravel road and meets Trail Ridge Road at Fall River Pass. Fall River Road is open July 4 through mid-October. Bear Lake Road, highway 36, and lower sections of highway 34, are open year round. Roads close temporarily, due to weather conditions.

Horseback Riding

Horses with guides can be hired at two location inside the park on the east side, or from a number of liveries outside the east and west park boundaries during the summer seasons.

Skiing & Snowmobiling

Glaciers and snowfields are dangerous, steep slopes that end in a jumble of jagged boulders. Many park visitors have been seriously injured or killed by sliding on these slick areas. Stay on designated trails to avoid such dangers.

Snow play is permitted in only two areas of the park – Bear Lake and Hidden Valley. Be aware that snow conditions can be icy and hard packed. Heed signs in snow play areas.

Wildlife Watching

Rocky Mountain National Park visitors have a passion for viewing wild animals, especially the big ones. With an elk herd numbering more than 3,000, about 800 bighorn sheep, numerous mule deer and a small population of moose calling the park home, it’s no surprise that wildlife watching is rated the number-one activity by a vast majority of Rocky’s three million annual visitors.

The park’s great large animal population makes it one of the country’s top wildlife watching destinations. But there is much more to see than these so called; charismatic megafauna.” Also found are nearly 60 other species of mammals; more than 280 recorded bird species; six amphibians, including the federally endangered boreal toad; one reptile (the harmless garter snake); 11 species of fish; and countless insects, including a surprisingly large number of butterflies.

Some basic knowledge of animal habits and habitats greatly enhances prospects of spotting Rocky Mountain’s wild residents. A few park favorites:

  • Elk can be seen anytime, a popular viewing period being the fall rut, or mating season. Look for elk in meadows and where meadow and forest meet. Elk spend much of their time at or above treeline during the summer, moving to lower elevations in the fall, winter and spring. Favorite feeding times: dawn and dusk.
  • Bighorn sheep are commonly seen at Sheep Lakes from May through mid-August.
  • Moose frequent willow thickets along the Colorado River in the Kawuneeche Valley on the park’s west side.
  • Otters were reintroduced into the Colorado River area and are doing fairly well. These animals are difficult to spot.
  • Mule deer are common and can be seen anywhere. They are most often found at lower elevations in open areas.
  • Bats feed over lakes and ponds at dawn and dusk.
  • Marmots and pikas favor rocky areas. Marmots are best seen on the alpine tundra along Trail Ridge and Old Fall River roads. Pikas, small, light-colored mammals are common in rock piles. Listen for their sharp, distinctive bark and watch for movement.
  • Clark’s nutcrackers, Steller’s jays, golden eagles and prairie falcons can be seen along Trail Ridge Road.
  • White-tailed ptarmigans, some of the most sought-after birds in Rocky Mountain National Park, are common but difficult to spot. For best results, hike on the tundra and look carefully. Ptarmigans usually remain still, relying on their natural camouflage for protection.
  • American dippers, or water ouzels, can be found along most streams. Listen for their loud call, similar to the rapid clicking of two stones together, as they fly up and down their territories.

Weather of Rocky Mountain National Park

The high country of Rocky Mountain National Park is noted for extreme weather patterns. Shaped by elevation, slopes, and exposure, these patterns can change rapidly.

Temperatures are often moderate at elevations below 9,400. At higher points like Bear Lake, Trail Ridge Road or Longs Peak. It may even snow in July.

A wide variation between day and nighttime temperatures is also typical of mountain weather. Summer days in Jul and Aug often reach the 70’s or 80’s and drop into 40’s at night.

Based on ten years of precipitation data, Estes Park receives approximately 13.10 inches of moisture every year. Grand Lake receives about 19.95 inches yearly. This precipitation comes in the form of rain or snowfall through the year.

The Continental Divide runs northwest to southeast through the center of the park atop the high peaks. This accounts for two distinct weather patterns, one typical of the east side near Estes Park and the other associated with the Grand Lake area on the park’s west side.

Summer:  sunny mornings, possible afternoon thunderstorms and cool nights.

Winter: cool conditions to blizzard conditions with extreme temperature variations. Weather conditions change quickly in mountainous areas and snow is possible year round. Wear appropriate dress for each season; comfortable clothing, dress in layers, rain gear, and sunscreen
