These are former slate mines which have developed amazing and ever-changing natural colouring through the constant dripping of mineral rich water. The caves were rediscovered in the early 20th century and became a tourist attraction. This part of Thüringia is also well worth exploring for its attractive forests, rivers, walking tracks, culture and hospitality.
