Cycling day trip from Postojna to Koper

Get ready for an awesome all-day cycling adventure from Postojna to Koper! Starting in Postojna—famous for its massive cave system (a must-see if you have extra time!)—the route clocks in at about 90 km, winding south toward the sparkling Adriatic coast.

Expect a mix of really nice surfaces: roughly half paved or asphalt and a good chunk of gravel and unpaved sections. You’ll roll along mostly quiet country roads and scenic tracks, which means fewer cars and more peaceful views. Prepare for a decent amount of climbing at the start (over 1,600 meters up!), but the payoff comes with a longer descent as you approach the sea.

You’ll end in Koper, a charming port city with a historic old town that feels like a slice of Venice. Grab a gelato or some seafood by the harbor! All in all, this route is hilly but rewarding, perfect for endurance riders who enjoy both inland forests and coastal vibes.
