After Stein am Rhein, the river landscape stretches out to the Untersee (visible to the left in the direction of travel), the western arm of Lake Constance. Nestled between the lake ridge to the south and the soft-sloped Schiener Berg to the north, this body of water dominates the region. Water sports are very popular, with numerous sailing boats and windsurfers taking to the waters in summer. Scenic gems abound on both lakeshores. Explore the Untersee in all its scenic splendour on an Untersee-Rhine cruise.
