Five Escapes Beyond the 14 Islands
Stockholm sits on 14 islands, but the best reason to leave them for a day is a town founded before the country existed in its current form. Sigtuna, Sweden’s oldest surviving town, was established in 970 CE along Lake Mälaren, and its pedestrian main street, Stora Gatan, still has 11th-century Viking runestones set into the ground alongside ruined stone churches.
A palace where the king still lives
Drottningholm Palace, a UNESCO World Heritage Site on Lovön island in Lake Mälaren, is the actual private residence of King Carl XVI Gustaf and Queen Silvia, not a museum piece pretending otherwise. Its Court Theatre still uses original 1766 wooden stage machinery, and the rococo Chinese Pavilion sits behind grand baroque gardens. Historic 19th-century passenger steamboats reach it in 50 minutes from City Hall quay, or take the metro plus a short bus ride; entry runs about 160 SEK.
A fortress town at the gateway to the archipelago
Vaxholm, an hour northeast by Waxholmsbolaget ferry from Strömkajen for about 95 SEK, is a wooden fortress town with pastel 19th-century fishermen’s cottages, coastal bakeries, and the massive 16th-century Vaxholm Fortress guarding the channel into the capital.
A sailing enclave two hours out
Sandhamn, on the island of Sandön, sits two hours east via Cinderella express catamaran from Strandvägen, a chic outer-archipelago retreat of pine-covered dunes, wind-swept granite beaches, and the Royal Swedish Yacht Club’s historic clubhouse.
Sweden’s academic capital
Uppsala, just 38 minutes north by SJ regional train, holds Scandinavia’s tallest church at 118.7 meters, its oldest university founded in 1477, the Gustavianum anatomical theater, and the ancient burial mounds at Gamla Uppsala.
Timing the ferries around the seasons
Vaxholm and Sandhamn both run on far more frequent boats in June through August than in the shoulder months, so a March or November visit means checking the Waxholmsbolaget and Strömma timetables before you fix a date, rather than assuming a summer frequency. Uppsala and Sigtuna, reached by train and bus rather than boat, run on a normal year-round schedule and make the safer picks for a winter day trip.
Verdict: Sigtuna and Drottningholm both pack into a single half-day and pair well together if you are short on time; Sandhamn deserves its own full day given the two-hour crossing each way, so do not try to combine it with anything else.
One concrete tip: buy the Waxholmsbolaget or Strömma ferry ticket through their apps before you reach the quay, since queues build fast on sunny weekend mornings and every kiosk is card-only anyway. For a multi-day plan that folds one of these in, see the 3-day itinerary .
