Hythe Pier stretches 700 yards from the centre of Hythe to the deep water channel of Southampton Water. It is the 7th-longest pier in the UK. It carries a pedestrian walkway on its northern side and the Hythe Pier Railway on its southern side.

The railway is the oldest continuously operating public pier passenger train in the world.  The narrow gauge trains date from WWI, now electric but originally battery powered, they were used in a mustard gas factory.
