The mountain bike route Grmeč (Crni Vrh) is situated in the west Bosnia and Herzegovina. Grmeč mountain has a long ridge and the highest elevation point is Crni Vrh summit at height of 1605 meters over the sea level. The route is easy and placed mostly on dry unpaved and carriageway roads. The final ascent from Pećinica pool to Crni Vrh is for hiking only. I used GPS navigation because  there is no labeled path to Crni Vrh. It takes about 45-60 minutes to Crni Vrh.  Near the descent section from Crni Vrh to Smoljana village there is a spring of water named Potoci. Due to unlabeled hiking trail to Crni Vrh and many unlabeled junctions a GPS unit with the uploaded route is a must for fast and safe navigation.

The mountain bike route Široki Brijeg - Čabulja is situated in the south Bosnia and Herzegovina. The route starts from Široki Brijeg town. The first section is placed on the paved road. The final ascent to Velika Vlajina peak is for hiking only. I left the bike in the forest and hiked to Velika Vlajina and Pjeskulja peaks. According to VGI-TK25 topo map Pjeskulja peak is labeled as the highest elevation point of Čabulja mountain at elevation of 1786 meters over the sea level. I checked with 2 GPS units the elevation of Pjeskulja and it's obvious that elevation is not more than 1750 meters in any case. It's a mistake on the topo map. So I can confirm that Velika Vlajina is the highest elevation point of Čabulja at about 1780 meters over the sea level. From the ridge of Čabulja you can get an amaizing view to Čvrsnica, Prenj, Velež mountains and Drežnica canyon too. Due to many unlabeled junctions a GPS unit with the uploaded route is a must for fast and safe navigation. Near the trail there are few water tanks. Be warned, before drinking the water from the water tanks the water should be filtrated with active filters.

The mountain bike route Ljubunčić - Velika Golija is situated in the south west Bosnia and Herzegovina. Ljubunčić village is a good access point to Velika Golija mountain. The most of the sections are placed on dry and rocky carriageway. Due to the steep ascent to the ridge, count to hike on some short sections. The downhill ride is possible from Veliki Vrh peak. Veliki Vrh is the highest elevation point of Velika Golija mountain. During the war in Bosnia and Herzegovina the war line was placed along Velika Golija mountain. At the ridge keep the ride on the carriageway and don't ride off the carriageway. You can ride the route in opposite direction too. Due to many unlabeled junctions the GPS unit with the uploaded route is a must for fast and safe navigation.

The mountain bike route Udbina - Ozeblin is situated in Lika region on southern side of Lička Plješivica mountain. Udbina municipality is the starting point of the mountain bike route. Ozeblin is the highest elevation point of Lička Plješivica mountain. From Ozeblin you can get a nice view on Lapačko Polje field, Gola Plješivica peak, Osječenica, Klekovača and Šator mountains. The MTB route is fast and easy and mostly placed on the rocky carriageway and unpaved road. The final ascent to Ozeblin peak is a short hiking section. Due to many unlabeled junctions the GPS unit with the uploaded route is a must for fast and safe navigation.
