From Foss Crooks Woods to York

The River Foss was historically navigable for nearly 12 miles up to Strensall and had six locks.

The Foss Navigation opened in 1796 and was extended in 1804. It was sold to York Corporation in 1852, and all but the last mile and Castle Mills Lock closed in 1859. Rowntrees bought the wharf and warehouse that had originally been part of Leethams Mill at the junction with the Wormalds Cut which was in use until the 1980s, and barges were bringing 200 tonnes of news print per week into York from Goole until 1997.

Navigating the Foss

There is no overnight mooring available on the River Foss, so it is necessary to book both passages. Boaters are requested to pass back down through Castle Mills lock within 2 hours. It is, however, an attractive mile-and-a-half of secluded and interesting waterway for a return trip within the day. Larger boats are advised to turn at Wormalds Cut; a 40’ narrowboat can turn further upstream; or two narrowboats breasted nose-to-tail can use one to drive up and the other to drive back.
