It is a short trail starting from the Archipelago national park nature centre Sinisimpukka (Blue mussel). It is short and easy even though the terrain is rocky. Information posts will take you through the different ages in history and rock formed during the times. You will also get to enjoy the view of the beautiful Baltic sea and the Finnish archipelago.
Purunpää wind shelter is located in the Ölmos-Purunpää conservation area. Best way to reach it is via Söderlångvik museum. You will pass the apple orchards of Söderlångvik and then follow the path marked with yellow across the forest. Most part of the trail through the forest is rocky and you will notice how trees have adapted to survive on the rocky terrain with very little soil. Wind shelter is located on a high point looking over Purunpää bay.
It offers a breathtaking view and wide variety of plant life. If you are lucky you might see a moose or an eagle.
