Hessenweg 4 (Teilstrecke Marburg - Grünberg)

Marsberg - Edersee - Kellerwald - Marburg - Grünberg - Bad Nauheim - Frankfurt - Darmstadt - Neckarsteinach

Covering 37.2 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. The trail is officially waymarked as H4, so look out for the trail markers along the way.

This route is part of the National Walking Network (NWN) — a flagship trail maintained to national standards, often following scenic or historically significant corridors.
