20. Gothenburg, Sweden
Its coast and islands have a good ferry service, a big amusement park, a science center, and good shopping. The old Haga is gorgeous and has cinnamon buns the size of plates and chocolate balls as big as your fist. Ferries, busses, and trams are easy to maneuver and the city is suitable for walking. There’s a big botanical garden and a nature museum with a stuffed whale. It has lots of coffee shops and you will need to have fika at least once or twice everyday.
