The bathing area is beautifully situated between two plank banks. Here you can find a suitable place to bathe. The higher the warmer. Do you think it's too hot? You have a cold inflow via a second watercourse. This way you can play with the temperature.

The barrier is there for a reason, because the area is indeed dangerous. The springs have a temperature of between 80 and 100 degrees Celsius. New cracks can appear in the ground at any time, as the ground has been changing and "moving" again since the 2008 earthquake. Keep a safe distance and follow the safety rules. Human reason should send warning signals in good time.
