Originally, Kolindsund was a large tunnel valley. Later, it became a sound that connected Grenaa to Randers. Even later, it turned into a lake. However, after Denmark lost Southern Jutland in 1864, the need for arable land became more pressing, and Kolindsund was drained.
A walk on the old lakebed
Today, artificial dikes and pumps ensure that the old lakebed remains dry. The pumped water flows into the straight North Channel, while the more natural drainage water flows through the much smaller but more winding South Channel. The area is rich in wildlife and a good fishing area for sea trout, pike, perch, roach, and bream.
