Seaweed walk along the shoreline
An adventure with seaweed diver and food creator Karolina Martinson on Vrångö, Saturday 13 September
Join a seaweed walk along the shores of Vrångö together with Karolina Martinson.
An inspiring walk that takes you out across the cliffs and beaches of the Vrångö Archipelago Nature Reserve. On Vrångö’s Hiking Day, you’re invited to a different kind of walk — a unique opportunity to learn more about the edible treasures along the shoreline and what lies beneath the surface of the sea.
Karolina will show you how to harvest seaweed sustainably, without disturbing the ecosystems, and give you tips on how to use seaweed and wild herbs in your own cooking. A simple seaweed-inspired fika with small tastings is included.
