If you're looking for a truly unique and challenging experience in the Black Hills, the Sunday Gulch Trail delivers. This 3.9-mile (6.3 km) route, with 661 feet (202 metres) of elevation gain, is officially rated as moderate for jogging with an estimated duration of 44 minutes, but don't be fooled; it's far more of a strenuous, 'hands-on' hike than a typical run. You'll scramble over boulders, navigate steep rock steps, and use metal handrails through narrow passages, all while surrounded by towering granite formations and the sounds of a gurgling creek.
Starting near the iconic Sylvan Lake Dam, the trail immediately immerses you in its distinctive environment. Be prepared for wet feet, as the path often runs directly through the creek, especially in wetter seasons. Parking can be busy near Sylvan Lake, so an early start is advisable. This trail is best suited for confident hikers who enjoy technical terrain and aren't afraid to get a little muddy.
The Sunday Gulch Trail stands out for its ancient geological features, with granite formations over two billion years old, and its immersive wilderness feel. It's a popular choice within Custer State Park for those seeking a blend of scenic beauty and a physically engaging adventure, offering a natural slot canyon-like experience that's unlike many other trails in the region. It's a fantastic alternative to more generic jogging routes if you're up for a real challenge.

While the trail is popular with trail running enthusiasts, it is generally considered difficult and strenuous for continuous jogging due to its rugged terrain. You'll encounter significant elevation changes, large boulders, and sections requiring scrambling and the use of handrails.
The terrain is highly varied and challenging. It includes dirt paths, but also numerous sections with rocks, boulders, and natural stairways. You'll navigate narrow gulches, steep descents and ascents, and multiple creek crossings, which means your feet are likely to get wet. Handrails are present in many steep, rocky areas to assist with navigation.
The loop is approximately 6.3 kilometers (3.9 miles) long. For jogging, it typically takes around 45 minutes, but this can vary significantly based on your pace and how much time you spend navigating the challenging sections. Many find it difficult to maintain a continuous jog.
The trail is easily accessible from the popular Sylvan Lake area within Custer State Park. Parking is available near Sylvan Lake, which serves as the primary trailhead for this route.
Yes, the Sunday Gulch Trail is located within Custer State Park, which requires an entrance license. You can purchase a daily or annual pass at park entrances or visitor centers. No additional permits are needed specifically for using the trail itself.
Custer State Park generally allows dogs on trails, but they must be kept on a leash. However, due to the extremely rugged and challenging nature of the Sunday Gulch Trail, with its steep scrambles, boulders, and handrails, it is often not recommended for dogs, especially larger ones or those not accustomed to such terrain.
Late spring through early fall is generally the best time. Be aware that snow and ice can persist on the trail until as late as June, making surfaces very slippery. Creek crossings can also be more significant in spring. Summer offers warmer temperatures, but the trail can be busy. Always check current conditions before heading out.
You'll experience exceptional and unique scenery, including towering granite formations, lush ponderosa pines, and ferns. The trail winds through canyons, alongside small waterfalls, and offers beautiful views of Sylvan Lake. The narrow, boulder-filled sections are particularly scenic, often compared to slot canyons.
Yes, there's a strategic difference. If you go counter-clockwise, you'll encounter the most challenging and steep boulder-filled descent into the gulch at the very beginning. Going clockwise means you'll face a steep climb through these same difficult sections at the end of your route.
Given the rugged and wet conditions, wear sturdy, waterproof or quick-drying trail shoes with good grip. Be prepared for your feet to get wet due to creek crossings. Comfortable, moisture-wicking clothing is advisable. Bringing water, snacks, and perhaps gloves for using the handrails or scrambling can also be beneficial.
Yes, the route also passes through sections of the Sunday Gulch Trail and the Sylvan Lake Trail, offering connections to other areas within Custer State Park.
