Hiking

The Philip S. Miller Park loop offers a fantastic blend of varied terrain and rewarding vistas, making it one of the top rated loop hikes near Castle Rock, CO. You'll traverse natural single-track trails through sagebrush and Ponderosa Pines, with the dramatic ascent of the Challenge Hill providing a strenuous workout and sweeping views of Pikes Peak and the Front Range. This moderate 6.2-mile (10.0 km) route involves 590 feet (180 metres) of elevation gain and typically takes around 2 hours and 47 minutes to complete.

Planning your visit is straightforward, as the park provides ample parking and facilities. However, be aware that dogs are not permitted on the Challenge Hill, so consider alternative paths if you're hiking with a canine companion.
