Hammarby Sjöstad is the argument that a city can be built well from scratch. Through the 1990s this was rail yards and oil depots on the south shore of Hammarby Sjö; from 2000 it became Stockholm's model district — apartments, canals, boardwalks and a closed-loop approach to water and waste that planners still fly in to study.
Three and a half kilometres, mostly flat, mostly on the water. Start at Luma on the Tvärbanan, where the old lightbulb factory's glazed tower marks the one survivor of the industrial years. Walk down Sjöstadsparterren, the stepped green spine, to the lake.
Then it's the strand — the shore boardwalk — east along Hammarby Sjö, with southern Södermalm rising across the water and the Sjövägen ferry stitching back to the city. The canals do the rest: Sickla Kanal, the locks where the lake steps down toward the sea, houseboats at the quays.
End at Sickla udde, the eastern point, where the Sicklauddsbron crosses to Sickla and the Tvärbanan loops you back around the south of the city.
