About Via Transilvanica
Via Transilvanica, the "road that unites", is a 1,400 kilometer long distance trail, a tourist route that crosses Romania diagonally from Putna to Drobeta Turnu Severin. It's designed for hiking, cycling and horse riding. Via Transilvanica is marked with painted markers, signposts and at every kilometer, there is an individually carved andesite stone, therefore all these milestones can probably become the longest art gallery in the world, which accompanies travelers along the way.
The trail crosses ten counties (administrative units of the country): Suceava, Bistrița-Năsăud, Mureș, Harghita, Sibiu, Brașov, Alba, Hunedoara, Caraș-Severin and Mehedinți and is divided into seven cultural-historical regions: Bucovina, Highlands, Terra Siculorum, Terra Saxonum, Terra Dacica, Terra Banatica, Terra Romana. In total, Via Transilvanica crosses 107 administrative-territorial units in Romania, and highlights the natural and cultural heritage of each region.
Via Transilvanica is a long-distance trail inspired by the history of other such trails in Europe, North America and beyond. But above all, it is a social project, so the focus is on the community. The project aims to bring to light places in the country, seemingly forgotten by the world and largely depopulated due to economic limitations, and bring them to life. This revival is due to the backpackers who, after a long day on the trails, expect a minimum of hospitality and at least one welcoming face to share stories with. This is what the road that unites is all about.
