Cascade Falls and Swimming Hole | Hot Springs SD

Setting and Character
Tucked away about 8 miles south of Hot Springs, Cascade Falls and Swimming Hole is one of South Dakota’s most inviting natural oases - a place where warm, spring-fed waters tumble through limestone terraces into emerald pools surrounded by cottonwoods and smooth sandstone. It’s small, unpretentious, and wonderfully local, a spot that feels half like a secret and half like a summer ritual.

Natural Formation and Waters
The falls are part of Cascade Creek, which flows from Cascade Springs, one of the warmest and largest natural springs in the Black Hills region. The water remains a steady 67°F (19°C) year-round, creating a mild microclimate even during the colder months. As the creek spills over a series of gentle rock ledges, it forms shallow basins perfect for wading and swimming. The limestone underfoot gives the pools a green-blue hue, glowing especially vividly in afternoon light.

The setting is intimate - not a roaring waterfall, but rather a soothing sequence of cascades no more than a few feet high. The flow creates a soft, rhythmic sound that carries through the trees, blending with birdsong and the faint rustle of prairie wind.

A Natural Swimming Spot
Cascade Falls has long been a beloved swimming hole for locals and travelers alike. The main pool, framed by smooth rocks and shaded by overhanging branches, is ideal for cooling off in summer. Children paddle at the edges while others float lazily downstream, the water clear enough to see every pebble below. On weekends, the area fills with the laughter of families picnicking on the grassy banks and the splash of swimmers jumping from the low ledges.

Unlike many cold mountain streams, the warmth of the spring-fed water makes this place unique - it’s comfortable even early in the season or during late autumn. Some visitors wade in even in March or October when the air is crisp but the water still inviting.

Scenic Surroundings and Wildlife
The falls are nestled within a pocket of cottonwood, ash, and willow trees, their roots weaving through layers of golden sandstone. The scent of wet rock mixes with the sweetness of prairie grass, and butterflies often flit through the sunbeams near the banks. Deer occasionally wander down to drink at dawn or dusk, and songbirds fill the canopy with sound.

A short walking path follows the creek, revealing small side pools and secluded corners where the water deepens or slows. The soundscape shifts subtly along the way - from bubbling trickles to quiet stretches where the creek runs glassy and still.

Visitor Experience
The Cascade Falls picnic area, managed by South Dakota Game, Fish & Parks, offers shaded tables, restrooms, and a gravel parking lot. The trail from the lot to the falls is short and easy, making it accessible for all ages. The atmosphere is informal and welcoming - no lifeguards, no entry fee, just a few signs reminding visitors to respect the environment and keep it clean.

On warm afternoons, locals often bring coolers, towels, and folding chairs, treating the place like their backyard swimming spot. Others come early in the morning to enjoy the solitude before the day heats up. The acoustics of the small canyon amplify the trickling water, making it an oddly peaceful place even when busy.

Historical Note
The area around Cascade Springs has been a gathering spot for centuries. Indigenous peoples valued the warm waters for their constancy and clarity, while early settlers in the 19th century used the springs for irrigation and small-scale recreation. The nearby town of Cascade, now a ghost town, once drew visitors hoping to enjoy the reputed therapeutic qualities of the mineral-rich water.

Impression and Atmosphere

Travelers often stop “just for a few minutes” and end up staying for hours, lulled by the easy rhythm of the falls and the gentle warmth of the water.

A Local Gem
