Take a look at some example ports
There's a vast range of places you can go to with P&O Cruises.
It is just nine miles long but the spectacularly snaking Geirangerfjord is the most photographed of all Norways fjords because of the sheer beauty of its setting.
Sailing through Norways beautiful Sognefjord, the worlds longest and deepest fjord, is one of the most memorable cruise experiences.
Because it was completely rebuilt after being destroyed by fire in 1904, Alesund looks quite different to other Norwegian towns along the country's west coast now better known as simply 'Fjordland'.
An Alpine town as well as a cruise port, Andalsnes nestles where the towering Romsdal Alps meet the northern end of the sparkling Romsdalfjord.
Estonia's cruise port Tallinn is also a fascinating medieval capital. This multi-faceted city and its architecture - a legacy of Teutonic, Polish and Russian rule - will have your eyes on stalks.
Nearby Geiranger might be more widely known, but the UNESCO World Heritage listed village of Hellesylt seems determined not to be overshadowed by its more famous neighbour.
