Black Elk Peak Trail #9 (Sylvan Lake)

This is the classic, most popular way to the highest point in South Dakota. Starting from the Sylvan Lake day‑use area, Trail 9 climbs steadily through pine forest and granite outcrops to the stone fire lookout atop Black Elk Peak. Expect big‑sky views, photogenic rock spires, and a satisfying summit payoff. The out‑and‑back is roughly 7 miles total (about 3.5 miles each way) with around 1,480 feet of gain—moderate overall but with a punchier final mile and a staircase finale to the tower.

The route is well‑traveled and generally well‑marked, but a few junctions can give first‑timers pause—study the map at the trailhead pavilion before you go. Underfoot you’ll see packed dirt, gravel, and plenty of granite; it’s rocky and uneven in spots, especially near the top. Granite spires flank the upper trail, and the historic 1938 stone fire tower caps the summit with 360‑degree Black Hills views.

Wildlife shows up often enough to keep it interesting—think deer, birds, and the occasional mountain goat. Geology fans will appreciate the ancient granite and metamorphic knobs and spires that make this area so distinctive.

Tips: start early. Summer afternoons bring fast‑building thunderstorms and even hail, and Trail 9 gets busy. Bring plenty of water, snacks, and layers (including a rain shell). Sturdy boots and trekking poles are helpful on the rocky grades. Bathrooms are at Sylvan Lake; there’s no water or services on the trail.

Want variety? Many hikers turn it into a loop by combining Trail 9 with Trail 4 for added Cathedral Spires scenery (expect a bit steeper, more rugged grade on Trail 4). If you prefer the gentlest grades, stick with Trail 9 out‑and‑back.

Best time to hike: May through October. Summer offers lush scenery but the biggest crowds; early fall is cooler, quieter, and often the sweet spot. Weekdays and early mornings win for parking, solitude, and calmer weather.
