ST519 Perelik - Smolyan

Stage in the Sultans Trail, a historic and cultural long-distance hiking route from Vienna to Istanbul.

Covering 16.3 km, this is a substantial hike requiring a reasonable base fitness. Most walkers complete it in about 3 hours and 37 minutes.

This linear trail moves from one end to the other without looping back. A return journey by transport — or retracing the path — is needed to get back to the start. Follow the ST519 waymarkers throughout to stay on the official trail line.

This trail belongs to the International Walking Network (IWN) — one of Europe's most ambitious cross-border hiking networks. Waymarking and maintenance follow international standards throughout.
