Castle Trail

Castle Trail is the longest trail in Badlands National Park and offers an iconic hiking experience through dramatic prairie landscapes, rugged rock formations, and expansive open views. Beginning at the Door and Window parking area, this well-traveled trail stretches five miles one way to the Fossil Exhibit Trail, making it a favorite for day hikers looking for a longer out-and-back adventure. Hikers can expect wide-open terrain, striking badlands scenery, and opportunities to spot wildlife along the route. With minimal shade and exposed conditions, Castle Trail is best enjoyed with proper preparation, plenty of water, and an eye on changing weather conditions.
