Some time ago I read about a cycle track from Dubrovnik to Mostar called the Ciro trail which now was the right time to find out what it’s about.
The Austro-Hungarian monarchy at the end of the 19th centory built a network of narrow gauge railway to link the southern Adriatic harbors on the coast like Kotor and Dubrovnik with the hinterland cities and central Europe. This network had been abandoned in the seventies. With the help of EU funds some parts had been converted into a cycle path in 2016 in order to support tourism.
Coming from Herceg Novi in Montenegro I started my Ciro Trail in Dubrovnik old town. First I worked up 300hm to a plateau where I joined the actual cycle path just behind the BiH checkpoint. The track is all flat termac and cuts through rocks and leads over damms filling up troughs. The area is completely depopulated here though the station buildings give a little glimpse of the glory times of this era. On an info board at Hum station where the railwayline split up one to Dubrovnik and one to Kotor it said that they had up to 60 trains per day running through this junction.
After around 60km on this superb path and my night stay at an artificial lake the path changed to heavy gravel where you thought they may have just removed the rails and nothing else. This rattling 20km section included also several unlit tunnels and led finally from the plateau down to the Neretva valley where I felt to come back into civilisation.
The third 40km section of the trail to Mostar was all along the river and parallel to the new standard gauge electrified railway line which links the harbor in Ploce with Mostar.
This trail was a true experience and is still an insiders tip for advanced cyclists. I would wish they can further invest in the incompleted sections so eventually it may be part of the Eurovelo network and bring tourism at a much larger scale to this area.
