There were four separate bathing pools to choose from with different temperatures in each, ranging from 90 degrees to 104 degrees. No chlorine or chemicals are used; the thermal spring water flows through continuously, much like bathing in a stream would be. We tried all four baths but agreed that the 98-100 degree one was best. The water we bathed in today, fell as rain 4000 years ago, can you imagine that? We would do this again; a must do if you are in Arkansas!
Steam could be seen all over town rising from fountains, storm drains, natural springs, leaking pipes and all manner of cracks and crevices. This National Park is considered an "urban park" as all of the hot springs are within the city limits.
Free spring water is available all over town. Spigots are provided that dispense the precious H2O at its natural temperature of 143 degrees. I asked the Park Ranger on duty if I could fill the 90 gallon fresh water tank in our RV with this spring water. She said no one had ever asked her that question, but she couldn't think of a reason why not. "My hose wouldn't reach, and I'd have to double park and hold up traffic" I replied, maybe next time.
Very few springs remain in their natural state. Most have been capped off to harvest this unique resource hidden deep below the earth's surface.
Bill Clinton's hometown too!
