Nacka is where big city and island meet. It is easy to get here by boat, car, bus, bicycle or the suburban Saltsjöbanan train, and the trip usually takes between 10 and 20 minutes from Stockholm proper.
History buffs get their fill either at the Battlefield Museum HAMN, or have a fika at the 18th-century country estates Svindersvik and Stora Nyckelviken. If you're into architecture, the designer hotel J at Nacka beach and the beautiful historic homes from the 20th century in Saltsjöbaden are sure make an impression. For art and culture, Dieselverkstaden is a creative space and exhibition hall well worth exploring, as are 20 newly-painted murals in the area that will make your jaw drop.
For the outdoor types, Hellasgården and Velamsund’s nature reserves are classics that never go out of style.
