OverviewLittle Devils Tower in Custer State Park. The canyon stream follows a west-southwest course north of the Needles/Cathedral Spires area before it turns northwest just above Sylvan Lake. Below Sylvan Lake, the stream drops more rapidly through large boulder fields and alongside of steep granite walls. Along its course, it passes below 7,000-foot Sylvan Peak and 6,458-foot St. Elmo’s Peak, both to the south. Eventually, the stream is joined by the Lost Cabin Creek on the north and a stream flowing in from the south at Johnson Canyon before it empties into Spring Creek Canyon near the junctions of highways 87, 89 and 385. Sunday Gulch drops 1,200 feet over its 6.5-mile length.
Black Elk Wilderness and the Black Hills National Forest. It’s almost all private property along the gulch from the Johnson Canyon/Lost Cabin Creek junction area downstream to where Sunday Gulch joins Spring Creek Canyon.
The Sunday Gulch Trail takes hikers through the best of what Sunday Gulch has to offer, which is probably why this is one of the most popular canyon hikes in the Black Hills. The route is so breathtaking that many hikers never realize there is even more to Sunday Gulch. Since the trail is in the core area of the Black Hills, granite formations are the most common feature, with tiny waterfalls and rock grottos in many places. Many of the boulders are covered with moss or lichens. Because of the high steep walls and thick forest in the gulch, there is little direct sunlight on the floor. This factor contributes to the longevity of snow and ice accumulations over the winter and into June, when the trail usually re-opens. Rock climbers are often seen in several locations from the granite spires in the Sunday Gulch Trail area over to the Needles area.
To see all of Sunday Gulch would require hiking Trail 4 from Little Devils Tower to Sylvan Lake, then picking up the shore trail there and hiking over to the Sunday Gulch trailhead. The Sunday Gulch Trail takes hikers to the end of Custer State Park and the western reaches of the Norbeck Wildlife Area. There is no trail down the gulch from there, but the public lands are open to off-trail hiking and the privately-owned land along the gulch can be viewed from Highway 87, as it passes through the lower section of Sunday Gulch to the junction with Spring Creek Canyon.
If you prefer to go the counter-clockwise loop, look for the narrow passage between high granite walls near the dam on Sylvan Lake. The other end of the loop is about 100 yards back toward the Sylvan Lake Store and behind a large granite outcropping. That trail comes out to a tiny bridge. Both trailheads on the loop are accessible from the 1-mile long Sylvan Lake Shoreline Trail. Blue diamond markers help keep hikers on the right course. The trail is normally only open from June through October. Ice and snow on the boulders makes hiking any other time of the year rather hazardous. Custer State Park rates the trail rated as strenuous.
Trail 4 from the Sylvan Lake trailhead follows the upper canyon of Sunday Gulch until the trail begins its steep ascent to the saddle between the Cathedral Spires and the Little Devils Tower. This stretch of trail is about 1.1-miles long and gains about 250 feet in elevation. Most people who hike along here do not associate this section with being part of Sunday Gulch, but it actually is the uppermost part. The Sylvan Lake Shore Trail provides a route between Trail 4 and the Sunday Gulch Trail. The map shows how this 1-mile loop trail connects the other two trails.
Red TapeTo access Custer State Park, you must have either a daily or annual park permit. The park does not allow open fires or firearms. Dogs are supposed to be on leash, but the park does not do a good job of enforcing that. There have been some problems caused by this, so pepper spray is not a bad idea. Camping is only in permitted areas. Please check at the entry station for the latest updated camping information. While some trails remain open all year, the Sunday Gulch Trail is closed in the winter. The park reserves the right to make additional closures as conditions warrant.
