Natural steam rising from the hot mineral pools at Old Town Hot Springs has been providing the public with a year-round bathing experience since the early part of the 20th Century. Centered on natural hot springs that flow into the pools, the water originates from the Heart Spring, which pumps approximately 150 gallons per minute and comes out of the ground like an artesian well (naturally without the use of pumps). The water then runs into an overflow system filling each of the pools.
