There are plenty to be found all over the place, but particularly in resort towns. The minerals within are said to provide health benefits, and they will certainly keep you relaxed. Hot springs exist for everyone, but they vary greatly. Some are separated by gender whole others are mixed, some are indoors, while many others are in stunning natural surrounds. Please note that you may be required to remove your clothing, and those with tattoos may not be permitted entry, depending on the place.
