Display Spring

Overview

Display Springs are the easiest place to see the park’s famous hot water in the wild—bubbling straight out of the hillside behind Bathhouse Row. It’s a short, shaded stop where the sound of running water and a bit of steam set the mood.

What You’ll See

• A small open-air spring complex with shallow pools, mosses, and blue‑green algae, framed by tufa—the light‑gray, “spongy” rock the hot water deposits as it cools.
• Two nearby spring vents: the upper one typically runs a touch hotter than the lower because it mixes less with cool groundwater.
• It’s photogenic, tranquil, and takes just a few minutes to appreciate.

Where It Is and How to Find It

It sits directly behind the Maurice Bathhouse on Bathhouse Row, along the Grand Promenade near Arlington Lawn. From Central Ave, use the stairs between the Maurice and Hale bathhouses to pop up to the springs.

Why the Water Is Hot (Short Version)

Rainwater seeps deep into the folded and faulted rocks of the Ouachita Mountains, travels down roughly 6,000–8,000 feet, warms via Earth’s normal geothermal gradient (no volcanic hotspot here), and then rides fault “superhighways” back to the surface. When the 143°F water reaches air, minerals fall out and build tufa—easy to spot around the spring mouths.

Ecology

Right at the vents you’ll notice heat‑tolerant algae and microbial mats clinging to the tufa. It’s a tiny micro‑ecosystem built around constant warmth and minerals.

Best Time to Visit

• Go early or late in the day for fewer people and softer, more flattering light for photos.
• Weekdays tend to be calmer than weekends along Bathhouse Row.
• The spring area is open daily and closes overnight; it’s an easy add‑on before or after a stroll on the Grand Promenade.

Know Before You Go

• The water is very hot—typically around 143°F. You can feel the thermal water at designated display springs, but keep it quick and use common sense.
• There are no outdoor soaking areas anywhere in the park. If you want a soak, use the bathhouses that pipe the spring water indoors.
• Drinking the thermal water is popular, but do it at the designated fountains along Bathhouse Row, not from the spring pools.
• No restrooms right at the spring; plan a quick detour before or after your visit.
