The good news is that there's a lot of great cycling in Croatia. There are many kilometres of unspoiled countryside and gorgeous national parks for mountain biking. The bad news is that Croatia is webbed with two-lane roads that offer great views but require nerves of steel as cars whiz by. The situation is better now that the coastal highway between Rijeka and Split is open as it draws trucks away from the narrower roads.
By far, the most popular cycling destination is Istria. The kilometres upon kilometres of gently rolling hills and rural roads make cycling a delight. Because cycling is so well organized in Istria, it's the easiest destination to arrange a self-guided trip.
There are about 60 marked mountain bike trails, almost 2600 km worth, but not all of them are plotted on the Istria tourist board maps. So far, you can follow maps of 1500km of marked circular trails, about 70% of which pass through unpaved country roads or forest paths.
Northern Istria has nine circular trails about 400km long. The mountainous terrain make these the most difficult trails but the views are spectacular. Look for ones that pass through the hilltop village of Motovun or the tiny town of Hum.
Central Istria has seven marked bike trails circling Pazin. These are relatively untouristed even in high season.
Southern Istria has the easiest trails. The 300km of marked trails are divided into eight sections with a lot of riding along the coast. There are two bike trails around Porec but the most beautiful trails are around Zlatni rt park outside of Rovinj. There are also three marked trails around Vrsar that pass through the Kontija forest with a sweeping view of the Lim Channel.
