DH and I are exploring Scandinavia and the Baltic bit by bit. Last year we started with Denmark. This year is Finland with a few days in Estonia to conclude. We will be travelling by train and ferry to Helsinki, think maybe 4 days there, then off to Turku for a couple of days. We would like to go somewhere scenic with good walking routes and lakes/water for the middle part. There seem to be so many national parks it is hard to choose somewhere. We could hire a car for this bit. Any ideas that would help us gladly received.
