Reykjavik, Iceland.
A long day in this port so time for a morning tour to see lava flows, lakes, boiling mud and jets of steam. Also a visit to Viking World Museum. Then a visit to the city centre later in the day.
Oriana was berthed a shuttle bus ride from the city. Walking into the centre was a 45 minute or so walk. It has a nice waterfront although the city itself had lots of building works going on. Very built up from when I visited almost 40 years ago!
