Sweden is much hillier and has fewer cyclists. The Baltic route takes you through beautiful agricultural and forested countryside with glimpses of the cold blue Baltic sea. Shivery cold to swim in even now. Wild camping is easy by quiet lakes that you can leap in to naked after a hot day in the saddle.
We loved Kalmar city and met a lovely Swedish family via www.warmshowers.org who recommended Kalmar castle. It’s an amazing 12th century castle complete with moat .
