Destination information

The bird wetlands of Vanhankaupunginlahti were a notable destination already in the early 19th century, when, for example, the bird painter Magnus von Wright made journeys there. The area has kept its appeal, and nowadays it offers good services as well, such as the accessible duckboard route to Lammassaari.

Viikki-Vanhankaupunginlahti is Helsinki’s biggest nature reserve. Vanhankaupunginlahti’s bird-rich wetlands are part of the Natura 2000 network.

The area of Vanhankaupunginlahti contains a variety of habitats: lush, herb-rich common alder forests, coastal meadows and reed beds. They are all easy to access, because the area boasts excellent routes and a variety of bird watching platforms, hides and towers.

When the ground is not frozen, visitors must keep to the paths in the reed bed areas.

Up-to-date information on the area is available on the website of the party responsible for its maintenance.
