Lammassaari is an island just off the coast of Helsinki, separated from the mainland only by a shallow bay in which reeds grow. The area is popular for bird-watching and enjoying a bit of nature in an urban area. The old, traditional boardwalks passing through the reeds were replaced by new structures that also allow access to visitors with reduced mobility.

How to experience nature in an urban context?

The Lammassaari boardwalks, which used to be the narrow traditional kind, have been a favourite of birdwatchers and local inhabitants for years. The new structures make it possible for a wider range of people to enjoy the calm natural site in the middle of bustling Helsinki. 

Delicate and modern design for enjoying nature 

Adjacent to the spot where Helsinki was originally founded in 1550, Vanhakaupunki, and near to the recently built district of Arabianranta, the area is a popular resting and nesting site for migratory birds. The 3.5 km accessible nature trail through a bed of reeds with bird lookouts connects Lammassaari island to the mainland. The boardwalk is floating, held in place with stilts that allow for the vertical movement. Along the trail there are bird-watching platforms, which have glass walls thus offering views for people of any height.
