Ulestraten-Bron, Sint Catharinastraat, Netherlands

Spa, a Belgian town, has some natural water sources.

A well-known spot close to Leuven where two springs supply 5 geometrically aligned lakes is known as the "Well-Known Site". The first, hertebron, is not accessible and is not suitable for drinking. The second, called "minnebron", is a well-maintained water source where many people go to get their water. A sign with an explanation and illustration of the local hydrology as well as a mineral analysis can be found at the outlet. Nearby is a church and numerous hiking trails. Water is fresh and almost constant in flow.
