The vast parkland of Ladugårdsgärdet is part of the 27-sq-km Ekoparken , the world’s first national park within a city. An impressive 14km long, its combo of forest and open fields stretches far into the capital’s northern suburbs. This section of it, reached by bus 69 from Centralstationen or Sergels Torg, boasts three fine museums and one of Stockholm’s loftiest views.
