Tallinn vs Vilnius

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.

Vilnius

Vilnius has a humid continental climate with warm summers and cold, snowy winters. Spring and summer (May–August) are the best months to visit, with long daylight hours and pleasant temperatures. Winter is cold and grey but has its own charm with Christmas markets and occasional snow on the baroque rooftops.

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.

Vilnius

Vilnius Old Town is very walkable — most major sights are within 20 minutes on foot of Cathedral Square. For longer distances, buses and trolleybuses are excellent and cheap. Bolt (rideshare) is reliable and affordable. The city is expanding its cycling infrastructure.

Walkability: Very high in the Old Town. Most UNESCO-listed sights are within 1 km of Cathedral Square. Cobblestones can be challenging; wear sensible shoes.
