Tallinn

Tallinn is one of the best-value capitals in Europe, and its biggest draw costs nothing: the UNESCO-listed medieval old town is free to wander, all cobbled lanes, town wall, and merchant houses that feel pulled from a storybook. Climb Toompea Hill for the free Kohtuotsa and Patkuli viewing platforms, which look out over the old town’s red rooftops and church spires toward the harbour. Kadriorg Park, the green grounds around Peter the Great’s palace, is free to stroll, and several historic churches open their main halls without an entry fee. Food and drink stay cheap by Nordic standards, so this is a rare spot where a few euros still buys a proper sit-down meal. Visiting in the shoulder months of late spring or early autumn brings lower accommodation prices and thinner crowds than the short summer peak. Tallinn also makes a budget base for a ferry day trip across the gulf to Helsinki or an onward bus south toward Riga.
