During a short visit in Stockholm last may I visited for the firt time the little island of Stora Fjäderholmen, about 20 minutes with the boat out on the archipelago. On the island there are several cafés/restaurant. During the spring time birds nest here and wherever you go you see seagulls or gooses. REally cute to see how to take care of their eggs, among all the toursit having picnic and sunbathing.
Handycraft shops and exhibition are part of the attractions on the island. Even a whisky distillery (Mackmyra Swedish Whishy) can be found there.
