Bicycling Croatia

Croatia rewards a bicycle more than almost any country its size. It has a thousand islands, a coast road with the sea on one side and mountains on the other, and an interior that almost no visitor ever sees. It also has hills, heat and some genuinely unpleasant traffic, and it is worth knowing which is which before you book.

Istria, which is where to start

The peninsula in the north west is the best cycling in the country and it is not close. Rolling hills rather than mountains, hill towns like Motovun and Groznjan on top of them, vineyards and truffle woods in between, and a network of marked routes.

The centrepiece is the Parenzana, a disused narrow-gauge railway from the Austro-Hungarian era converted into a trail running from Trieste through Slovenia and down into Istria. Railway gradients mean it climbs gently where a road would be brutal, and it goes through tunnels and over viaducts. About 130 km in total, and you can ride sections.

Istria also has the best food in Croatia, which matters more on a cycling trip than on any other kind.

The islands

The islands are the other obvious answer, and the ferry network makes island hopping by bike genuinely practical. Bikes travel cheaply on Jadrolinija ferries and you can build a route that never repeats itself.

Some are easier than others. Cres and Losinj have a long spine road and light traffic. Korcula and Hvar are hillier than they look from the boat, and Hvar in particular has a serious climb out of the town. Mljet is largely national park and is the gentlest of them.

Pag is the strange one: a treeless limestone landscape scoured by the bura that looks like the surface of the moon and is hard, exposed riding.

The coast road, with a warning

The Magistrala runs the length of the Adriatic and it is spectacular. It is also narrow in places, has no shoulder for long stretches, and carries heavy traffic through July and August including coaches and campervans driven by people who are not used to their own vehicle.

Ride it in May, June, September or October. Riding it in August is an unnecessary risk, and plenty of experienced cyclists simply will not.

The interior, which nobody rides

Inland Croatia is empty, green and almost entirely ignored by visitors. The Lonjsko Polje wetlands, the Slavonian plains in the east, the hills of Zagorje north of Zagreb with their castles.

One thing has changed here that matters. Croatia was declared free of landmine-suspected areas on 1 March 2026, the last of them cleared more than thirty years after the war. The old advice about staying on marked paths in former front-line areas no longer applies, and the interior is open in a way it has not been in living memory for anyone under forty.

Practical

Spring and autumn. Summer inland is very hot and the coast is too busy.

Rental is easy in the tourist centres and limited elsewhere, so if you want a specific bike, bring it. Trains take bikes on some services; buses take them at the driver's discretion and for a small charge, which is an unreliable plan on a busy summer route.

Croatia joined Schengen and adopted the euro on 1 January 2023, so a cycling route that crosses from Slovenia or Hungary has no border formalities and no currency change.
