"The easiest (and for kids, the most fun) way to access Ljubljana Castle is to take the 70m-long funicular that leaves from the Old Town...cable cars leave at regular intervals throughout the day." Full review

"A fixture on the city's skyline. The medieval castle boasts thick stone walls and houses a plethora of historical spaces, including a chapel, an open-air prison, a gunpowder room and a lookout tower." Full review
