Estes Park /ˈɛstɪs/ is a statutory town in Larimer County, Colorado, United States. A popular summer resort and the location of the headquarters for Rocky Mountain National Park, Estes Park lies along the Big Thompson River. Estes Park had a population of 5,858 at the 2010 census. Landmarks include The Stanley Hotel and The Baldpate Inn. The town overlooks Lake Estes and Olympus Dam.
Before Europeans came to the Estes Park valley, the Arapaho Indians lived there in the summertime and called the valley "the Circle." When three elderly Arapahoes visited Estes Park in 1914, they pointed out sites they remembered from their younger days. A photograph at the Estes Park Museum identified the touring party as Shep Husted, guide; Gun Griswold, a 73-year-old judge; Sherman Sage, a 63-year-old chief of police; Tom Crispin, 38-year-old reservation resident and interpreter; Oliver W. Toll, recorder; and David Robert Hawkins, a Princeton student.
