Trehörningsviken
Trehörningsviken is a sheltered inlet just outside Nynäshamn where you can drop anchor among the islets and enjoy some genuine Stockholm archipelago calm. The three-cornered shape of the bay gives it a tucked-away feel, and it's well known as a favorite spot for the local sailing club NSS, which has moorings nearby — so you'll be in good company. The island of Lacka lies just to the north if you want to explore further.
