Europäischer Fernwanderweg E4 (von Gresten nach Wien: Main Route)

E4 Österreich (von Gresten über Wilhelmsburg, Hainfeld, Heiligenkreuz nach Wien Kahlenberg) Main Route

Covering 205.2 km, this is a true long-distance trail best approached as a multi-day journey through varied terrain.

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 E4 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.
