Along the old trunk road between Stockholm and Nynäshamn, two stubby peninsulas protrude into the inner archipelago, towards the south-east. They are the Häringe and Hammersta nature reserve, which is one of the areas of Södertörn richest in plant life.
Ramblers and nature lovers travel from far away to the beautiful agricultural landscape of the area in order to follow the riding trails and rambling trails of the reserves, view the ancient remains, go owl spotting, and see the gnarled old giant oaks here.
Furthermore, many red-listed species can be found here, many resting birds, as many as seven of Sweden’s bat species, wild ivy and an old castle, Häringe Slott, offering accommodation and restaurant, onetime residence of Sten Sture the older, Torsten Kreuger and Axel Wenner-Gren.
Muskån on the Hammersta peninsula is mating grounds for sea trout, eel and ide, among others.
