Serbia: E4 Long Distance European Trail from Krivelj to Sokobanja

This track is the route of the E4 European Long Distance Trail from Krivelj to Sokobanja in Serbia based on Map 11 of "Rambling through Serbia at a slow pace", a booklet published by Planinarski Savez Srbije (PSS), the Serbian Mountain Association. While the track is close to the trail described in the booklet, I cannot guarantee it is the exact route or indeed the best, all I can say is that I successfully walked it in April 2018. More details of my trip can be found in my blog johnpone4serbia.blogspot.com.
This trail starts near Krivelj where my previous trail ends (https://www.wikiloc.com/hiking-trails/serbia-e4-long-distance-european-trail-from-vratna-monastery-to-krivelj-24708578). It follows various farm tracks to Borsko Jezero, a popular resort beside a man made lake, before climbing the nearby, tree covered summit of Tilva Njagra. Then it crosses to the scenic Lazarev canyon (where I met a hiking group from Serbia4Youth (www.serbia4youth.org)). There is a cave at the start of this limestone canyon but the trail climbs up the ridge to the south, with some gorgeous views, eventually reaching the summit of Malinik. After this peak, the trail passes through various villages to reach Rtanj. A pyramid shaped mountain with an air of mystery above a partially abandoned mining village. Then it is downhill to the tidy, holiday spa town of Sokobanja.
After Sokobanja, my next trail is at https://www.wikiloc.com/hiking-trails/serbia-e4-long-distance-european-trail-from-sokobanja-to-jalovik-izvor-25472000

Subsequent to my trip the Mountaineering Association of Serbia published a route for the E4 in this area, see https://pss.rs/terenipp/krivelj-soko-banja/.
