If you can't or don't want to take a Šarganska osmica train, take a walk on roads and paths near the tracks. You will see much of the same sights, visit intermediate stations (i.e. Golubići station featured in Kusturica's film Life Is a Miracle) and will be able to rest and admire to your will, not bound by train times. Ask locals for drections.
Küstendorf, Mećavnik
Traditional village just next to Mokra Gora conceived by, and home of, Serbian film director Nemanja Kusturica. Drvengrad is clearly visible from Golubići station and easily reachable by road (you park and you pay an entry fee) or by stairs from Šargan Eight station. The village is a nice mix of traditional and modern, wood and stone. It has streets and squares named after people Kusturica likes and admires (i.e. Ingmar Bergman, Diego Armando Maradona). It also has tourist services and modern facilities. Here Kusturica organizes annual international film festival which has interesting selection of films and attracts many people.
