Hi there. Just got back from our fjord cruise. To confrim, once IONA leaves Hellysylt it cruises part of the the way down Geraingerfjord, passes the Seven sisters waterfall, does a 180 degree turn in the fjord, and then sails back up - it does not go all the way down Geraingerfjord. I would check out the excursions offered nearer the time, but the road links between Hellysylt and Gerainger are not great.
