One of Sweden's richest bird lakes. Commonly known for the amount of cranes that stop at the lake before flying on towards and from their breeding grounds. On pillars in the lake you find the visitor center Hornborgasjön, an information center including an exhibition about the lake's history and bird life. Hornborgasjön is an over 4000 hectare large nature reserve. The reserve includes mainly the lake and its shoreline, but also some of the old farmland east of the lake.
Djupadalen is a nature reserve with amazing views over Åslesänkan, a hollow created by gushing water when the ice sheet retreated at the end of the Ice Age. The local flora includes juniper, rosehip, thyme, and dwarf thistle.
By following the valley you can walk in a unique way through the entire sequence of strata that form the plateau mountain landscape.
