This paper investigate historical premises of the old salt routes, roads called the ancient or medieval trade route on which the salt was barely transported from the extraction point to the trading one, back then being an extremely valuable trading product. Nowadays these roads have an important role in promoting the saline health resorts in Transylvania developed on the former mining exploitations. The tourist potential and image analysis reveals that both those in desolation and those recently upgraded are lacking a unified promotion that could bring them great profit by raising the number of tourists. We also bring some proposals for these thematic tourist routes.
