Stora Alsjön

Welcome to the Stora Alsjön nature reserve in Södertälje municipality. This is an excellent area for a pleasant hike through hilly, forested terrain. The reserve has multiple lakes, with the largest being Stora Alsjön and Lilla Horssjön. Go for a picnic and enjoy the scenic view over the water from the steep cliffs or from a picnic table by the beach.

The forests here have been largely left untouched. The bog and the old trees create a strong feeling of wildness. Since a large part of the forest has not been affected by modern forestry, many endangered species have made their homes here, including many rare fungi.

Section 12 of the Sörmlandsleden trail passes through the reserve. You can hike the blue-marked trail together with the orange-marked Sörmlandsleden trail to make a 4 km loop that will take you through the southern parts of the reserve.
