An old tramway viaduct crosses the valley, showing how the region developed industrially in the 1800s. This structure reveals how people once harnessed the natural water power of the area.
The name refers to old mills that once used water from this site. Visitors can observe how the flowing water shapes the landscape and daily rhythms of the surrounding area.
