Evans Plunge

Long before any pool was built, the warm springs of this valley were known and valued by the Lakota and the Cheyenne, who regarded the healing waters as a place set apart. Tradition holds that this was neutral, shared ground where different nations could come for the water's benefits, and the springs remain part of the older, living history of the Oceti Sakowin homeland in the Black Hills.

That reputation for healing waters carried into the settler era, when the town of Hot Springs grew up around the promise of the mineral springs. The whole community, with its distinctive pink sandstone buildings, was built on the idea that these waters were good for body and spirit, and Evans Plunge became the centerpiece of that vision.

What makes Evans Plunge remarkable is that it is filled and warmed entirely by nature. Mineral springs bubble up through the gravel floor of the pool, delivering a steady flow of naturally warm water that keeps the pool at a comfortable temperature the year around, without any furnace or heater. The same flow drains continuously, so the entire volume of water refreshes itself many times over.

That constant turnover means the water is always clean and moving, a living spring rather than a still tank. Swimmers can feel the springs welling up beneath their feet, a direct connection to the geology of the Black Hills, where rain and snowmelt sink deep, warm in the earth, and return to the surface here, at the southern foot of the hills.

Evans Plunge opened in the 1890s, named for a local businessman who developed the springs into a bathhouse and pool, and it has operated continuously ever since, making it one of the longest-running swimming attractions in the region. Generations of families have learned to swim in its warm water, and it has been a summer institution for the whole southern Black Hills.

Over the decades the facility has grown and modernized, adding slides, play features, and other amenities that keep it lively for today's families, all while preserving the historic spring-fed main pool at its core. That blend of old and new lets visitors enjoy modern fun while swimming in the very same waters that drew people here more than a century ago.

The town of Hot Springs is worth exploring in its own right, a community of handsome pink sandstone buildings that give its historic downtown a warm, unified glow, all built during the boom the springs created. The Fall River runs through town, and the whole place has the easygoing feel of a small Western spa town at the edge of the mountains.

Because Evans Plunge is indoors and naturally warm, it is a year-round attraction, a welcome swim in the heat of summer and a cozy one when snow lies on the surrounding hills. Paired with the nearby Mammoth Site, Wind Cave, and the wider southern Black Hills, it anchors an easy day in a quieter, less crowded corner of the region.
