Copenhagen vs Tallinn

Copenhagen

Copenhagen has a temperate oceanic climate with mild summers, cold winters, and frequent overcast skies. Rain is possible year-round but rarely heavy. Daylight varies dramatically, from nearly 18 hours in June to just 7 hours in December.

Tallinn

Tallinn has a humid continental climate moderated by its Gulf of Finland coastline. Summers are mild and pleasantly long with up to 18 hours of daylight in June. Winters are cold, dark, and occasionally dramatic — the sea can partially freeze and the Old Town under snow is spectacular but icy. The transitional seasons are short. Northern lights are visible on clear nights from November through March.

Copenhagen

Copenhagen has an integrated transit system covering metro, S-tog (suburban trains), and buses, all using the Rejsekort smart card or DOT single tickets. However, cycling is by far the most popular way to get around — the city has over 450 km of dedicated bike lanes.

Walkability: Central Copenhagen is flat and very walkable. Stroget, the main pedestrian street, connects Radhuspladsen to Kongens Nytorv. Most major sights in the old city are within a 30-minute walk of each other. Just watch for bikes when crossing lanes.

Tallinn

Tallinn has excellent public transport covering the whole city by tram, trolleybus, and bus. Public transport is completely free for registered residents — one of only a handful of cities in the world to have made this permanent policy since 2013. Tourists pay, but fares are very cheap. The Old Town is entirely walkable. Bolt (founded in Tallinn) makes taxis among the cheapest and most transparent in Europe.

Walkability: The Old Town and adjacent districts are highly walkable on flat ground, though Toompea Hill involves a moderate climb. Cobblestones in the Old Town can be tough with luggage — rolling bags struggle. Winter icing significantly affects walkability. Overall the city is compact and pedestrian-friendly for its size.
