The sun was bright almost all day so my boat trip around Oslo-fjord was exceptionally lovely. I went to the Viking Museum, the Norsk Folkemuseum (could have stayed there a few more hours but my legs were tired and I wanted to catch the boat back), and the Kontiki Museum.
After resting my legs a bit, I took a walking tour of the older part of Oslo. There are still several museums I must see before I leave here tomorrow evening!
