Alderfer/Three Sisters Park

Alderfer/Three Sisters Park is a Jefferson County Open Space property in Evergreen, Colorado, about 30 miles west of Denver in the foothills of the Front Range. It holds a solid 4.6 rating across 40 reviews, making it one of the more well-documented outdoor destinations in the area. Evergreen itself sits at around 7,000 feet and draws both locals and day-trippers from the Denver metro looking for trail access close to the city. The park's multi-use trail network makes it a legitimate option for horseback riders who want quality terrain without driving deep into the mountains.

Alderfer/Three Sisters Park offers designated multi-use trails open to both hikers and horseback riders, giving equestrians access to forested foothills terrain with views toward the Denver basin. Riders typically bring their own horses, using the park's trailheads and parking areas equipped to handle horse trailers. The trail system winds through mixed conifer forest and open meadows, with routes ranging from easy flat sections to more challenging climbs toward the rock formations the park is named for. Hiking is equally popular here, and the park is managed to keep foot traffic and horse traffic safely separated on key sections.

Alderfer/Three Sisters Park serves the Evergreen community and surrounding Jefferson County, including riders coming from Conifer, Morrison, and the western Denver suburbs. It's a reasonable drive from Golden and Lakewood as well. Day visitors from the broader Denver metro regularly make the trip out to Evergreen specifically for this park's trail system.
