Reykjavik vs Tallinn

Reykjavik

Iceland's weather is famously unpredictable — "if you don't like the weather, wait 15 minutes." Mild for its latitude thanks to the Gulf Stream, but wind and rain are constant companions. Layering is essential.

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.

Reykjavik

Reykjavik is very walkable — the downtown core is compact. There's a bus system (Straeto) but most visitors rent a car to explore beyond the city. There are no trains in Iceland.

Walkability: Downtown Reykjavik is very walkable and compact. Beyond the city center you'll need a car or bus.

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.
