The remains of the smelt mill are impressive and well worth exploration. One prominent feature is the large intact chimney. The long building nearest the track is where the smelting took place. It used to have four ore furnaces, producing 2000 tons of lead per year. Much of the stone from these buildings was removed in the 1930s to build a new Methodist chapel at Muker.
Surrender Bridge is in the Yorkshire Dales National Park.
