The Heder spring area in Salzkotten offers a fascinating insight into the natural water landscape of the region. In a small area, 20 springs emerge here, which unite to form a green-blue stream. Some of these springs emerge impressively from beneath houses and farms. After just a few meters, they power a historic mill whose old wheel is still intact. A Kneipp basin invites you to refresh yourself and offers a soothing cool-down for tired legs. The area, which was last redesigned in 2006/07, offers an oasis of peace and relaxation away from the traffic. Guided tours are available by arrangement and offer in-depth insights into the special features of this unique natural area.
