I have once swam in a cave that was known for its sulfur stones, cleansing and therapeutic, it was a majestic experience. A greek volcanic island, Milos. The waters inside the cave were hot, opening the skin pores for greater benefits... Thank you for this reference, it took me back to that beautiful memory :)
This is not my picture but I found it online, the whole island is full of caves...beautiful... the volcano is not active but it has volcanic land, stones, sulfur, healing places. I went there around 23-24 years old I believe. I did a week of walking and camping here and there. I was by myself, it was wonderful, got a little burnt by the hot sun reflections around through the stones! but I absolutely loved it.
