Once a narrow-gauge railway, the 123 km Parenzana Trail now connects charming towns across Croatia, Slovenia, and Italy. Ride through rolling vineyards, olive groves, and coastal landscapes with panoramic Adriatic views. Historic tunnels and bridges add character, while the gentle gradient makes it ideal for leisure cyclists. Stop for truffle dishes, seafood, and local wines along the way — this cross-border route blends history, nature, and gastronomy in a uniquely Mediterranean ride.
