Hot Water Cascade

Hot Water Cascade is Hot Springs National Park’s largest visible spring, set into the slope at Arlington Lawn on Bathhouse Row. Water emerges beside the Grand Promenade, passes beneath the path, then spills down a steep rock face into two pools. You can see the park’s famous thermal water moving through the open landscape right in town. It’s an easy stop to add to a Bathhouse Row walk; allow 10 to 15 minutes to watch the water and take in the setting.

Look first for the spring’s outlet near the Grand Promenade, then follow the water under the path and down the hillside. From below, the fall and pools give you the whole route in one view. Tufa Terrace Trail reaches the promenade above if you want to look down from the spring’s upper side. For a photo, step back far enough to include the cascade and the lower pool together; the drop is what makes this spring feel like more than a fountain.

Arlington Lawn’s open spring gives you a glimpse of a different Bathhouse Row. The water was here long before the bathhouses, and this cascade suggests how the hillside may have looked before the area was built up around the springs. It’s a striking contrast: a natural source of hot water flowing in the middle of a district best known for its historic bathing houses.

The park’s thermal water began as rain about 4,000 years ago. It sinks through porous Bigfork Chert and Arkansas Novaculite, reaches depths of roughly 2,000 to 8,000 feet, warms naturally underground and rises back through fractures in the rock. The water emerges at about 143°F on average, then cools as it reaches the pools. These springs aren’t volcanic or heated by magma; the warmth comes from the natural heat deep in the ground.

From the Fordyce Bathhouse Visitor Center, walk north along Central Avenue toward Arlington Lawn; the cascade is just left of the pavilion. The upper view is reached by Tufa Terrace Trail and the Grand Promenade. The spring is listed as wheelchair accessible, and benches are nearby. This is a quick look at flowing water, not an outdoor soaking pool; the park has no outdoor soaking places. If you want to bathe in the thermal water, plan on a bathhouse instead.
