Blue River Resort water is classified as Hot Springs. The temperature of the water at the source is 60°Celsius and only fluctuates downward when rain water enters the hole.
The temperature of the water for each pool is controlled with the addition of domestic water. Except the cold water pool, all others provide the full therapeutic benefit of the “hot springs” classification.
