Horseshoe Park is aptly named because of its history. A 500 foot thick glacier once covered the entire valley and as the glacier moved slowly over hundreds of years a distinct U-shape was etched out of the valley. Mountains were carved and rock debris was carried out of the valley and a large horseshoe shape was etched. As the glacier melted and dissipated lateral moraines were formed. All that was left behind were sediments that became the settled meadows of Horseshoe Park. The park is situated in the Rocky Mountain National Park near Aspenglen, Colorado.
The park is open daily from 9 am to 5:30 pm and closed each evening. During the summer months, from mid-June to about the third week of August the park hours are slightly extended from 9 am to 6 pm. There is no overnight camping in the park but there is a picnic area along the loop around Endo valley. The picnic area is one-half mile along a one-way dirt road to the summit on the Old Fall River Road. The Fall River Visitor Center is open during park hours to provide information and maps as well as address safety concerns with visitors of the park.
