The medieval castle on the green hill above the old town, reached by a glass funicular or a short woodland walk, with an Outlook Tower over the red roofs, an exhibition on Slovenian history and a courtyard that is free to wander.
Prešeren Square, the Triple Bridge, the Dragon Bridge and Plečnik’s riverside market colonnade: the car-free heart of Ljubljana, best seen on foot or with a guide who knows the stories behind the bridges.
An hour of optical tricks, tilted rooms and photo-ready illusions on Congress Square, open daily into the evening. The easy rainy-day win for families and anyone who likes a playful break from churches and bridges.
The official city pass: the castle and funicular, a river boat cruise, a guided city tour, more than twenty museums and galleries, the zoo, city buses and a bike hire, for 24, 48 or 72 hours.
