We eventually found somewhere to stay on an archipelago near Turku. It was quite a large campsite, so not really what we usually head for but it served a purpose and was in beautiful surroundings with lots of wild life.
We spent a couple of days here. It was great for running and cycling but the weather was a bit cool. We left early in the morning to catch the ferry from Turku to Stockholm. We were lucky to see a small fox who watched us drive by completely nonplussed by our presence.
