Overview
Little Devils Tower is the less-trafficked alternative to the Cathedral Spires, a granite formation accessed by a 4-mile trail in the central Black Hills near Hill City. The trail gains 800 feet to reach the base of the formation, where scrambling terrain begins and rock climbing routes access the main faces. For hikers who've done the Cathedral Spires trail and want a comparable experience without the Needles Highway tourist concentration, Little Devils Tower offers the same Black Hills granite character with significantly fewer people.
The name is no accident: the formation resembles a smaller version of Devils Tower National Monument in northeastern Wyoming, the same type of igneous intrusion exposed by erosion, shaped into characteristic columns and faces by the same geological forces. The similarity is approximate but recognizable, and the Black Hills context gives it a regional coherence.
The Route
Miles 0 to 1.5: Trailhead to Base. The trail begins at the Little Devils Tower Trailhead and climbs through ponderosa pine forest, gaining elevation consistently. The trail is less developed than the major Custer State Park trails. Expect a narrower track with occasional loose sections. The formation comes into view in the final half-mile of the approach, growing in apparent size as the trail closes the distance.
Miles 1.5 to 2: Lower Scramble Zone. The maintained trail ends at a clearing at the base of the main formation. From here, use-trails and the beginning of the scrambling terrain are visible. The lower sections of the spire faces can be explored by hikers comfortable with uneven, rocky terrain without a maintained path. Marked climbing routes (for technical climbers with equipment) access the upper faces.
At the Formation: The view from the scrambling zones and from the base is across the Harney Range to the south and west, with the Black Elk Peak area visible on clear days. The rock surface of Little Devils Tower shows the characteristic pink-gray granite of the Black Hills igneous core.
Return (Miles 2 to 4): The trail returns the same way it came. The descent is straightforward on the approach trail.
Rock Climbing
Little Devils Tower has established technical climbing routes that attract climbers from across the Black Hills and beyond. The primary routes are on the main face and are well-documented in the regional climbing guide. Seasonal raptor nesting closures may apply on certain routes from March through July. Check with the USFS Hell Canyon Ranger District before planning a climbing trip.
Hikers who do not climb technically should stay on the maintained trail and the lower use-trail scramble zones visible from the trail end. Unroped scrambling on the upper sections carries real fall risk and is not recommended without technical experience.
Getting There
From Hill City (on US-385 in the central Black Hills), follow local roads west toward the national forest boundary. The trailhead is approximately 5 miles from Hill City on forest roads. A passenger vehicle can reach the trailhead in dry conditions; high clearance helps after rain.
From Rapid City, take US-16 southwest to US-385 south, then follow signs toward Hill City and the forest road approach. Total drive time is approximately 45-60 minutes.
No fee is required at this trailhead. No restroom or water is available. Carry all water from the car. Many hikers carry 1.5 to 2 liters for the 4-mile round trip; individual needs vary.
Connecting to Other Trails
Little Devils Tower is in the central Black Hills between the Sylvan Lake area (south) and the Pactola Reservoir area (north). The Cathedral Spires Trail is the more accessible granite spire experience for comparison. The Centennial Trail section near Pactola is the best longer route in the same part of the forest.
Practice Leave No Trace principles at the formation, particularly around the base where vegetation grows in rock crevices. For the broader context of Black Hills public lands, see national forests vs. national parks.
