Rankin Ridge Nature Trail

Overview

A tidy, 1.0‑mile loop that climbs 239–275 feet to the highest point in the park, Rankin Ridge is the quick-hit viewpoint you do between longer stops. Expect a steady, manageable climb, big Black Hills panoramas, and on crystal-clear days a faint rim of the Badlands far to the east. Most hikers take 30–40 minutes. Benches along the way make it easy to linger.

Route and What You’ll See

Hike the loop clockwise for the best flow: ascend the narrower singletrack through ponderosa pine (shadier and more scenic), then descend the wider old service road with broad, continuous views. The footing can be rocky or gravelly in spots. At the top sits a steel fire tower (built in the 1950s) that marks the park’s high point; it’s closed to climbing, but the ridge delivers the views you came for. You’ll move from pine forest to an open, airy ridge—watch for shifting light across Buffalo Gap grasslands and the eastern Black Hills.

Wildlife and Nature Notes

This ridge isn’t a wildlife hotbed, but you may spot prairie dogs near the trailhead and, occasionally, bison in the broader area (more often near the main road). Deer and elk are possible in the surrounding hills. Stay alert, give all animals space, and enjoy the soundtrack of wind in the pines.

Tips and Trail Strategy

Clockwise is friendlier: shade on the way up, views on the way down. The return road is wider and easier underfoot—also the better choice if you’re managing a stroller. Parts of the descent are sun-exposed; start early in warm months and bring water (there’s none on trail). Some hikers report poison ivy—longer pants help, and staying on trail is smart.

Getting There and When to Go

The signed spur to the trailhead is off SD‑87, about five miles north of US‑385 near the visitor center. There’s a gravel lot right at the trailhead—don’t accidentally park along the road below. Clear mornings and late afternoons offer the best light and cooler temps; go on a clear day if you’re chasing those long-distance views. If you want more solitude and wildlife after this sampler, consider tackling the longer Lookout Point loop elsewhere in the park.

Know Before You Go

No pets are allowed on this trail. There’s no drinking water, and the tower itself is locked. Roads can occasionally close—check current conditions before you head out. Expect some loose gravel on the descent.
