Cycling day trip from Ljubljana to Postojna

This route takes you from the heart of Ljubljana, Slovenia’s lively capital, all the way to the famous cave town of Postojna. You’ll cover about 57 km—perfect for a solid day out. Expect a real mix of terrain: a good chunk on peaceful, quiet roads, but nearly a third of the ride is on gravel and unpaved surfaces, so bring a bike that can handle a little adventure.

Ljubljana is known for its charming old town, vibrant riverside cafes, and the iconic Dragon Bridge—definitely worth a quick coffee before you roll out. The ride gently climbs out of the city, winding through green Slovene hills and forests, with some 1000 meters of total ascent to keep things interesting.

As you approach Postojna, keep an eye out: this small town is world-famous for the jaw-dropping Postojna Cave, a massive karst cavern system. Whether you’re here for a quick visit or an underground tour, it’s the perfect reward after a day in the saddle. Don't forget to snap a photo before heading for a well-earned pastry at one of the local bakeries!
