Thermal Water Display Pools

Overview

These are the park’s outdoor “show-and-tell” springs—managed pools and cascades that let you see (and carefully touch) the famous thermal water right on Bathhouse Row. They’re not soaking pools; think of them as living exhibits where steaming water courses over mineral‑built rock.

Where to Find Them

You’ll encounter several features within a short walk:

• Display Spring behind the Maurice Bathhouse
• Hot Water Cascade on the Arlington Lawn (largest visible spring)
• Maurice Historic Spring Area between the Hale and Maurice
• Promenade Seep behind the Quapaw
• Fordyce Fountains between the Fordyce and Maurice
• Administrative Fountain at the south end of Bathhouse Row

What You’re Seeing

The water you’re touching started as rain in the Ouachita Mountains, sinking thousands of feet along ancient faults, heating naturally underground, and returning to the surface after roughly 4,000 years at about 143°F (62°C). As it cools topside, dissolved minerals—especially calcium carbonate—precipitate out to form light‑gray, spongy tufa around the pools and cascades.

How the Springs Are Managed

Most spring openings are capped to protect water quality and route flow to a central system supplying bathhouses and public fountains. The park and scientists monitor temperature, chemistry, and flow; the system can deliver hundreds of thousands of gallons per day. A small portion is directed to these outdoor displays so you can witness the springs in action.

Safety & Etiquette

• Do not soak or wade—these are look‑but‑don’t‑bathe features.
• The water can still be scalding at the source; only brief touch is advisable.
• Rocks and paths near the cascades can be wet and slick. Obey signs and barriers.

Make It a Short Stroll (or More)

Pair the displays with an easy walk along the Grand Promenade or duck into the Fordyce Bathhouse Museum and Visitor Center for context and exhibits. If you want a true soak, head to the operating bathhouses on Bathhouse Row; if you want a taste, bring bottles for the public thermal and cold “jug” fountains around town.

Best Time to Visit

Weekdays and early mornings or later evenings are typically calmer along Bathhouse Row. Light is softer at the ends of the day, and the displays photograph well without harsh glare. Everything is an easy, urban walk between features, so you can comfortably fit them in before or after other downtown stops.
