Slovenia's capital appeals to vacationers seeking a historical, scenic getaway that doesn't break the bank. Located about halfway between the Mediterranean Sea and the Alps, Ljubljana offers a postcard-worthy setting filled with charming architecture, expansive green spaces and bike- and pedestrian-friendly streets. The picturesque Ljubljanica river weaves its way through the Ljubljana Old Town area, where the bulk of the city's can't-miss attractions – which are all free to visit – reside. You can cross the river via stunning bridges like the Dragon Bridge and the Triple Bridge, one of several Ljubljana sights created by Slovenian architect Jože Plecnik. Other old-world locales, such as Ljubljana Cathedral and Prešeren Square, are a short stroll away from the river's banks.
