As Europe’s Greenest Capital 2016, Slovenia takes its eco-friendly practices seriously. That’s why the city center is pedestrian only. So, renting a bike and touring the city is a can’t-miss activity. You can see the top spots all in one day, including the pink Franciscan Church, the charming Prešernov trg square, and tranquil Tivoli Park. Not to mention, sticking to the streets is a great way to catch all of Ljubljana’s famous bridges, like Triple Bridge, Dragon Bridge, and Butchers Bridge.
