Zlatni Mostove Stone River Walk

The Zlatni Mostove stone river walk explores one of Vitosha's best-known natural features, a long field of large granite-type boulders that lies in a valley on the mountain above Sofia, Bulgaria. Known in English as the Golden Bridges, the stone river sits at about 1,410 m within Vitosha Nature Park. No scheduled public bus reaches the site, so visitors arrive by car or taxi on the Vitosha mountain road. Roadside and small lot parking is available near the area, which fills on sunny weekends. No permit is needed for day walks.

The walk is about 1-2 km round trip and takes around 1-1.5 hours including stops, with roughly 100-150 m of gentle climbing along the edge of the boulder field, so it is firmly in the easy category. The path is a mix of dirt, stone and boulder hopping. Walkers can follow the bank of the stone river, which is a natural scree-like flow of rocks left by past climate processes. Stepping onto the boulders is common but demands care, as surfaces are uneven, can be slippery after rain and have gaps between rocks.

Shade is intermittent: part of the route is shaded by spruce, while the boulder field itself is open and sunny. A small stream is audible beneath the stones in places, giving the feature its river name. Visitors can walk as far up the stone river as they like and turn back at any point, since the walk is out-and-back. The area also acts as a trailhead for longer hikes toward Cherni Vrah.

There is a small restaurant and kiosk in the vicinity, but water on the trail itself should not be relied on, so a bottle is advisable. Hiking shoes with real grip are important because of the rock surface. Children enjoy the scrambling, though parents should supervise closely near gaps. In winter the boulders can be snow-covered or icy, so the walk is best done on dry days in warm months.
