Local lore says that the volcano used to spew fire, lava, and ashes, but was turned into mud by a local priest who believed it was the work of the Devil, and he was able to banish him with the help of holy water. Today phosphates, sulphur and magnesium bubble up through the mud, which is reached by climbing up a steep wooden staircase. After a 5-10 minute soak in the mud, one climbs back down another, slippery wooden staircase to wash off in a nearby lake. As with any tourist attraction, paid options are available, including a massage in the mud and a bath in the lake.
