The Rheintaler Höhenweg, or Rhine valley high path, is a hiking trail along the western side of the Rhine valley in Switzerland. It starts in Rorschach on the edge of Lake Constance, and follows the Rhine river southwards (upstream) through wine fields, fruit orchards and cheese-making countryside to finish in Sargans. The total route covers around 100 km (62 mi), and reaches a maximum altitude of 1430 m (4700 feet).
This route is not the same as the Rheinhöhenweg Trail, which is much farther north, downstream in Germany.
