Whether your itinerary allows for overnight sailing (as opposed to a few hours for a door-to-door journey centered on air travel) or you are doing it for pleasure, the trip from Copenhagen to Oslo (or reverse) on DFDS Seaways is likely to leave overall positive impressions. The ship leaves the port of origin at 4:15pm and reaches the destination at 9:45am the following morning. If you are into scenic travel, you have several hours of navigating Øresund and Oslofjord when the sun is up. If you are into shopping and entertainment, you are on a big cruise ship, with all attendant amenities.
In 5 words: Plenty to see and do.
For your first visit you need no less than two and a half days to be able to fully appreciate the city and all of its major sights while keeping pleasantly unhurried pace. Add another day for trips further afield.
Distances are walkable in the city center, you are unlikely to need use of public transport much, except for going further afield.
Love its colorful buildings and juxtaposition of old and new.
Don’t miss: climbing to the top of the Church of Our Savior.
