Eldorado Canyon State Park
Welcome to the Eldorado Canyon State Park Department!
Eldorado Canyon is a hidden treasure right in Boulder’s backyard! Whether it’s hiking amidst the towering sandstone cliffs, picnicking along scenic South Boulder Creek or climbing Eldo's sheer golden walls, Eldorado Canyon State Park truly has something for everyone! Discover this hidden jewel and take home memories that will last a lifetime.
Eldorado Canyon State Park selected as one of Ten State Parks You Can't Miss by SmarterTravel.com
Eldorado Canyon offers over five hundred technical rock climbing routes luring climbers from around the world to challenge their skills on “Eldo’s” golden cliffs. The beauty of this canyon engages all who visit. Hike or mountain bike our picturesque trails that vary from easy to difficult and connect with Boulder's trail systems. Enjoy a picnic by, or fish in, scenic South Boulder Creek. In the winter, Eldorado Canyon offers cross-country skiing and snowshoeing.
The quiet beauty of the park can be experienced best in the cooler months, and during summer weekdays. Please avoid the summer weekend crowds! Eldorado Canyon almost always reaches vehicle capacity on weekends and holidays from May through September, i.e. after filling the Park, vehicles are only admitted when space becomes available.
