Cedar Sink Trail

Overview

Cedar Sink is a compact, above‑ground look into Mammoth Cave’s karst world. The official loop is about 1.0 mile total and typically takes 45–60 minutes. Expect roughly 295 stairs and around 150 feet of descent/ascent to get into and out of the sink—short on mileage, but not flat. It’s a great add‑on after a cave tour or a quick standalone hike when you want geology without a big time commitment.

Route and Terrain

From the trailhead, a rolling, roughly 6‑foot‑wide dirt path leads about 0.5–0.75 miles to the rim. Then the stairwork begins: multiple flights drop you into the 7‑acre sinkhole, where footing is generally flatter. You’ll find several small creek crossings on wood plank bridges. In wet periods, look for “karst windows” where surface flow disappears underground—an above‑ground peek at the park’s subterranean river system. If you prefer to put most of the downhill first, take the loop clockwise so the climb out feels a touch more gradual.

What You’ll See

The sinkhole itself is the star—cliff‑rimmed, lush, and dramatic. Spring and summer bring a strong wildflower show; keep an eye out for Tall Larkspur, Foamflower, and Bellwort. Butterflies are common on calm, warm days. In wetter spells, watch the creek enter one side of the sink and vanish into the limestone on the other.

Logistics and Tips

Parking is at the trailhead and can fill during busy times; arrive early for an easier spot and a quieter experience. The trail is not accessible due to the stair sections. Leashed pets are allowed; service animals are welcome. Surfaces can be muddy or slick after rain—sturdy footwear helps. After heavy rain, expect flowing water and extra caution on wet rock and stairs. No reservations are needed for this hike, and it’s an efficient way to experience the park’s surface geology without committing half a day.

Best Time to Hike

Late April through May is prime for wildflowers; October shines for foliage. Mornings offer cooler temps, easier parking, and calmer conditions for photography. The route is well‑shaded, which keeps it pleasant even in midsummer, though bugs can be a thing—pack repellent.
