Horsetooth Mountain Open Space
Horsetooth Mountain Open Space (consisting of Culver, Soderberg, and Hughey Open Spaces) is a scenic 2,711 acre park located on the west side of Horsetooth Reservoir. It is located 4 miles from Fort Collins and 12 miles northwest of Loveland. Elevations vary from 5,430 feet at Horsetooth Reservoir to 7,255 feet at the top of Horsetooth Rock. Horsetooth Rock is one of the most outstanding features in the park and is a very familiar landmark in Fort Collins and Larimer County. According to a local European legend, Horsetooth Rock is the remains of the heart of an evil giant, cut in two by the powerful Native American, Chief Maununmoku, thus protecting his people from the giant's wrath. The open space is also known for waterfalls and tremendous views of the Front Range. Horsetooth Mountain Open Space offers over 29 miles of trails for hiking, mountain biking, or horseback riding. The mild foothills climate offers year-round opportunities.
Parking is available at two locations: the Horsetooth Mountain Open Space trailhead parking area, immediately off CR 38 E approximately 5 - 6 miles west of the intersection of Harmony and Taft Hill in Fort Collins, and the Soderberg Open Space trailhead parking area, accessed by following signs to Inlet Bay off of Shoreline Drive. Drinking water is available at the trailhead. Please be sure to carry enough for your hike or ride. This is a very popular open space, so if you should arrive and find the parking lot full you will know that the trails are at maximum capacity. Please consider one of our other open spaces, such as Devil's Backbone Open Space or Rimrock Open Space for your outdoor enjoyment that day, and come back to Horsetooth Mountain Open Space another time.

Management Plan
Management plans for this historic homestead and open space area provide a second trailhead and a trail access into the popular Horsetooth Mountain Open Space as well as a trailhead for the future Front Range Trail. Educational and interpretive materials at this site will provide information on the historic buildings still present as well as the ranching heritage of this area. The complete Soderberg Homestead Draft Management Plan can be found online.
Future Vision
The bulk of Horsetooth Mountain Open Space was purchased from the Soderberg family in the mid-1980s. This site is the historic location of the Soderberg Ranch homestead. The acquisition of the homestead will accommodate a new trailhead and parking areas for visitors further expanding the points of access to Horsetooth Mountain Open Space. It is anticipated that this trailhead and trail will be open in late 2004.

Management Plan
Because this property is an extension of Horsetooth Mountain Open Space it will also host all of the same recreational opportunities found around the rest of the park. This will be accomplished by integrating the trail system to this area of the park. The Hughey Property is managed as part of Horsetooth Mountain Open Space.
