Krankesjön, Nature reserve and lake in Skåne County, Sweden.

Krankesjön is a nature reserve and lake in Skåne County featuring wetlands, reed beds, and diverse natural habitats across a large protected area. The landscape includes different environments that support a wide range of plants and animals throughout the seasons.

Krankesjön was lowered sharply around the turn of the twentieth century, turning a fairly deep lake into a shallow one with reeds along the shores. The exposed lakebed was then used for peat extraction. The shallow water now draws ornithologists and outdoor visitors, and because it freezes early it is used for ice skating. Ålabäcken, flowing north, is the lake's outflow to Kävlingeån.

Three birdwatching towers stand around the lake: a small one at Sjöstorps ängar near Revingeby, and two larger ones at Almen near Lund University's Stensoffan research station and at Silvåkra. The Silvåkra tower is the largest; Skåneleden passes it, and a rest area with a grill and wind shelter sits beside it. Lund Municipality built a boardwalk there out to the reed edge, leading to a hide for watching birds.

The lake is shallow and freezes early, giving good skating in winter. Three bird towers stand around the water: a small one at Sjöstorps ängar near Revingeby, and larger ones at Almen by Lund University's Stensoffan research station and at Silvåkra, the largest, where Skåneleden passes and a rest area with grill and wind shelter is laid out. From the Silvåkra tower a boardwalk built by Lund Municipality leads to the reed edge and a hide.

The lake was lowered sharply around 1900, turning it from fairly deep into a shallow body with reeds along the shores; the exposed bottoms were then used for peat extraction. Ålabäcken, flowing north, is its outflow to the Kävlingeån.
