Geiranger is beautiful but there is not a lot to do there. The little church up the hill is nice, the walk alongside the waterfall is worth doing if you can cope with the uphill / downhill walking and there is the fjord centre further up the hill. The gift shop sells the same sort of tourist items as elsewhere in Norway and there is a place to buy coffee. I guess that private tours may be few and far between because they are likely to be used by any other ships or relocate to Hellesylt for Iona. If you like sitting outdoors in a beautiful, peaceful place, Geiranger is an ideal place to be, if you want activity, you may be disappointed. I have not stopped in Hellesylt, but having sailed past it, it seems to be little different from Geiranger.
