Why Challenge Hill Is One of the Toughest Short Hikes in Douglas County | Castle Rock CO
Challenge Hill may be short, but it packs a serious punch – and it’s one of the most unique quick workouts in Douglas County.
Challenge Hill is a short but intense workout in the heart of Castle Rock. Often called the “Mini Incline” in reference to the famous Manitou Incline, this 200-step stair climb rises about 178 feet in elevation – and it’s a lot tougher than it looks. The views from the top, however, make it well worth the effort.
Challenge Hill
The main segment of Challenge Hill is about 1/10 of a mile long, featuring 200 steps and nearly 200 feet of elevation gain. Don’t let the short distance fool you—this steep climb will get your heart rate up quickly.
Once you reach the top, there are two options for descending. You can head back down the steps, though this can be challenging due to foot traffic (and tough on the knees). The other option is to run or walk down the adjacent 1/2-mile loop trail, which is often the preferred route.
Challenge Hill is open year-round, and you’ll typically find individuals and groups on the hill in all seasons. Many people don’t stop at just one ascent—repeating the climb is a popular way to build endurance and get an intense workout. Some even add a weight vest for an extra challenge or use it for training for steeper climbs and races.
There is no shade on either the hill or loop trail. Summers can be hot and dusty, while winter conditions may include ice or packed snow, making the climb more difficult and requiring extra caution.
