Rheinfähre Ellikon–Nack, Ferry crossing between Ellikon am Rhein and Nack, Germany.

The Rheinfähre Ellikon–Nack is a passenger ferry across the High Rhine, linking Ellikon am Rhein in the Swiss municipality of Marthalen with Nack in the German municipality of Lottstetten. Since 1905 it has run as a roller ferry, and the current vessel, the «Rüedifaar» (ZH 4200), has been in service since 1979 and belongs to Marthalen.

This ferry crossing has operated for around 500 years and was modernized in the early 1900s with a roller system. The technology made the crossing safer and more reliable than before.

The ferry is part of the inventory of historic transport routes of Switzerland. Until 1972 a customs post stood at Ellikon for ferry passengers. Swiss customs officers may use the boat to cross armed from Ellikon over German territory to the Swiss right bank at Rüdlingen.

The ferry operates only during warmer months, mainly on weekends and holidays in the afternoon hours. Visitors should be flexible with departure times and check current operating days beforehand.

The ferry is a Rollfähre, a reaction ferry propelled by the river current against a fixed cable, in use here since 1905. The vessel «Rüedifaar» (ZH 4200), built in 1979, belongs to the municipality of Marthalen. Swiss customs officers may use it to cross armed through German territory to the Swiss bank at Rüdlingen.
