 The Nature Rambler Section's Committee of Railway Employee's Union developed this issue on the national level in 1953, and published the first brochure, which showed the whole route in map sketches.Later, organisation and control of the National Blue Trail movement was taken over by the Hungarian Rambler's Association "Friends of Nature" (MTSZ) in 1961.But the Blue Trail was known only among hikers until the beginning of the 1980s, when Hungarian TV broadcast a series about the route of the Trail.
