Stockholm / Svinninge Marina

Svinninge Marina sits right in the Stockholm archipelago near Åkersberga, about 40 minutes from the city — close enough for a weekend trip, far enough to feel like you've actually escaped. You'll find water and electricity on the pontoons, decent showers, and a small shop for basics, though you'll need to fuel up elsewhere. It's especially well-regarded as a spot to haul out and get work done on the boat over winter.
