The bike trail is well marked. You need to follow the number three on the blue signposts in a clockwise direction.
The roads on the Castle Bike Trail are mostly asphalt, compacted gravel and dirt, with short stretches turning into a forest path. Therefore, the trail is suitable for mountain or trekking bikes with at least a front suspension and tires with a good tread depth.
Please take extra care on the forest path section of the trail between the villages of Šmihel pod Nanosom and Predjama, which can prove very rough for trekking bikes. If you are not comfortable with steep descents and a rougher ride, skip that section and go from Landol straight to Predjama.
This will take you down a section of the road used in the past by the Romans and local furmani (cart drivers).
Along the Castle Bike Trail, you will also find five bike repair stands and six pumptracks where you will be able to test your skills in a dynamic ride across the bumps.
