Store Blåkilde is a typical basin spring located near Rold Skov, south-southwest of the lake Madum Sø. The water has a very characteristic sapphire blue color. On a sunny day, the clear water mirrors the sky in blue colors from sapphire to turquoise.
To get to the spring from the parking lot, you must follow the path that is approximately 1 km long and goes through a marshland, which makes it difficult to use the path in a wheelchair if the weather is bad.
Please notice, that the spring is preserved, which is why it is forbidden to collect animals and walk in the spring.
