The hot spring overflowing from the big soup marsh flows down the waterway and forms this free natural foot soup in a flat place. The water temperature is not very high, you can step on the river bed, because the sand at the bottom of the pool is warmer, but pay attention to safety. We sit on the bamboo row and soak our feet while we pick apples (buy them at 7-11 for breakfast, and bring them to the place where we eat them). Of course, the apple core and the towel for foot cleaning must be taken away. There is no trash can here.
