I have found a hot spring water in eastern Congo (DRC) at the area called Uvira, about 16 km from lake Tanganyika and 30 kms from the border of Burundi and DRC (Gatumba). According to the natives, the water flows everytime of the year and I had a chance to touch the water.
I can rightly guess that the temperature of this water is about 85 deg. celcius, and it comes in small ponds spread over an area of 10 squire meters.
The people around are usually associating this water with medical treatment, and they have put fences of man and women separately. They usually come to have a bath and claims to be good to their muscle toucher.
