The port cities of Helsinki and Tallinn are separated by just a 50-mile strip of the Baltic Sea.
But while they share similarities in location, the neighbouring capitals offer a totally different vibe making them perfect for a twin-centre break.
It’s easy to travel between Finland and Estonia’s capitals via a picturesque three-hour ferry route, but you can cut down on journey time, and maximise sight-seeing time, by hopping on one of the nine daily 20-minute Finnair flights between the two.
