Flakfortet is a mans made island build up with sand to protect the sound between Denmark and Sweden built over 100 years ago. We had a good light wind sail from Malmo. The island is privately owned with a great harbour, if somewhat expensive . The island is full of tunnels and Fortifications from WW1 and 2. We were walking along one tunnel using our phones as torches when a generator cut in for the islands restaurant Brenda got spooked and we left quickly.
