Cycling day trip from Postojna to Divača

Roll out from cave-famous Postojna and cruise across the Slovenian Karst to Divača. It’s about 37 km of rolling terrain with roughly 535 m of climbing and a net descent into Divača, topping out around 705 m. Expect a real mixed-surface ride: nearly half on farm/forest tracks, about a third on quiet roads with a touch of cycleway, and plenty of gravel. A gravel or trekking bike (35–40 mm tires) will feel right at home.

The route threads through pine woods, karst meadows, and dry‑stone walls, with big-sky views toward the Nanos massif. Services can be sparse between towns, so top up bottles in Postojna and carry snacks. Watch for loose gravel on descents and a brief busier stretch of road near settlements.

Fun fact: Postojna is world‑known for its vast show cave and nearby cliff-hanging Predjama Castle. At the finish, Divača is the gateway to the UNESCO‑listed Škocjan Caves—and a historic railway junction—so consider a short detour to the caves to cap the ride.
