I finally got to make that trip to Phoenix. Stopped off at El Dorado hot springs in Tonopah, Arizona. They were very busy and according to the owners that is not unusual this time of year. We had planned on staying the night but they told us that we needed at least a two weeks ahead reservation to spend the night. They only have 3 private rooms. So we used one of the private hot tubs called "The Duck Pond". It had a small pond with some fish in it and at least one small turtle. The hot tub was perfect for the two of us, but it has room enough for 4 or 5 soakers. There was also a cold shower and cold tub. The water flowing through the hot tub was the perfect temperature and the tub was very clean! I don't know what was in the water as far as minerals etc. but they told us it was ph balanced at 8.2 with a temp of about 105. Well when we got out we noticed that our skin was very soft and smooth. I am looking forward to returning before the weather gets too hot. The place may look old and run down but our experience was great!
