I will be in Gothenburg from the 5th of July for 2 days then will travel to Copenhagen. I am sure that we can pack in a lot of the city sights in 2 days - if there is anything that is a MUST do please let me know. I saw there is a hop on/off bus and the paddan boats. My main question however is this - how best to travel to Copenhagen and which would be the most 'scenic' route. I can see that I can travel to Helsinborg then across to Denmark or to Malmo then ferry across. I assume train would be the best way to travel, or in fact hire a car? Any advice would be most appreciated.
