The High Rockies, or high country, is a term for a region of the U.S. state of Colorado. It commonly includes Larimer County, Jackson County, Routt County, Grand County, Summit County, Eagle County, Lake County, and Pitkin County. Some notable towns there include Estes Park, Walden, Steamboat Springs, Grand Lake, Winter Park, Breckenridge, Dillon, Vail, Leadville, and Aspen. The geography of the High Rockies has some of the most rugged parts of the Rocky Mountains and consists of the Front Range and mountainous topography to the west, much of which is on or near the Continental Divide. Known for pine forests and winding roads, the former mining towns there have been reinvented by wilderness tourism such as hiking, cycling, fishing, and most especially both cross-country and alpine skiing. Notable ski resorts include Copper Mountain, Keystone Resort, Steamboat Ski Resort, Beaver Creek Resort, Buttermilk, Aspen Highlands, Snowmass, and Aspen Mountain. The High Rockies are also the location of Rocky Mountain National Park and Arapaho National Forest.

Dream Lake is a high alpine lake located in Rocky Mountain National Park in northern Colorado, located east of the continental divide. The lake is at the base of Hallett Peak and access is via the Bear Lake trail head. It is known for its views caused by surrounding steep cliffs, and is a destination for casual hiking.

Tyndall Glacier is a small cirque glacier in Rocky Mountain National Park in the U.S. state of Colorado. Tyndall Glacier is on the east side of the Continental Divide and in a cirque to the north of Hallett Peak. Tyndall Glacier is both an ice and a rock glacier, with the lower portions of the glacier being composed primarily of rock debris and a small portion of ice. Tyndall Glacier is named after John Tyndall, an Irish scientist and Alpine mountaineer who in 1861 first ascended the Weisshorn in 1861. He also made an early attempt on the Matterhorn prior to its first ascent. In 1861, Tyndall identified carbon dioxide as a heat-trapping greenhouse gas; the glacier that bears his name appears to be retreating.

Ptarmigan Pass, elevation 12,168 ft (3,709 m), is a mountain pass that crosses the Continental Divide in Rocky Mountain National Park in Colorado in the United States.

The Bear Lake Comfort Station, also known as the Bear Lake Generator Building, in Rocky Mountain National Park was designed by the National Park Service Branch of Plans and Designs is the National Park Service Rustic style and was built in 1940. It was converted for use as a generator house at an unknown date and apparently no longer serves its former purpose as a public toilet. It was added to the National Register of Historic Places on January 29, 1988.

Stones Peak is a 12,922-foot-elevation (3,939-meter) mountain summit located in Larimer County, Colorado. It is situated in Rocky Mountain National Park, one mile east of the Continental Divide and 11.5 miles (18.5 km) west of the community of Estes Park. Stones Peak is part of the Front Range which is a subrange of the Rocky Mountains. Precipitation runoff from the mountain drains into tributaries of the Big Thompson River. Topographic relief is significant as the summit rises over 3,900 feet (1,200 meters) above the Big Thompson River in Forest Canyon in two miles. The peak is a prominent landmark viewed from Forest Canyon Overlook along the Trail Ridge Road.

The Fern Lake Trail in Rocky Mountain National Park, Colorado, runs 4.8 miles (7.7 km) from Moraine Park in the eastern part of the park westward to Fern Lake, the first portion of the trail following the course of the Big Thompson River. The trail was first informally established in the late 1880s as a way to get to "The Pool," a wide spot in the Big Thompson where a small lodge predated the 1915 establishment of the park. The trail was improved by the Estes Park Protective and Improvement Association between 1907 and 1912, with a new bridge at The Pool. Two years later the trail was rebuilt to maintain no more than a 10% grade and to provide better access to Fern and Marguerite Falls. In the 1920s Fern Lake became a popular winter destination for skiing, complete with a lodge. From 1933 the trail was rebuilt over three years with Civilian Conservation Corps labor, building retaining walls and adjusting the trail's alignment.The Forest Inn at The Pool closed in 1951, and Fern Lake Lodge closed in 1960. Folksinger Judy Collins and her then-husband Peter Taylor ran the lodge in the summer of 1958, welcoming hikers a respite from the trail. It was demolished by the Park Service in 1968 as they eliminated concessions within the park. The trail is notable for its association with early tourism development in the park and for its Civilian Conservation Corps-executed construction. The Fern Lake Trail was listed on the National Register of Historic Places on February 28, 2005.
