Explore Britain's longest staircase lock—a dramatic engineering marvel of eight locks lifting boats 64 feet on the historic Caledonian Canal near Fort William.

Neptune's Staircase at Banavie, near Fort William in the shadow of Ben Nevis, is a remarkable feat of civil engineering built by Thomas Telford between 1803 and 1822. This staircase lock comprises eight interconnected locks on the Caledonian Canal, designed to lift boats 64 feet (20 meters) and remains the longest staircase lock in Britain. Each lock measures 180 feet by 40 feet, and the entire system takes approximately 90 minutes for boats to pass through. Visitors can witness the impressive hydraulic operation of the locks, which were originally hand-powered using 36 capstans requiring 126 full revolutions for a complete transit. Today, modern push-button hydraulic controls have dramatically reduced transit times while maintaining the historical character of this 19th-century structure. The base plinths of the original capstans remain visible, offering a tangible connection to the site's engineering heritage. The venue is kept by Scottish Canals and is open to the public as a free outdoor attraction. Its setting in the Highlands, with views toward Britain's tallest mountain, makes it an ideal stop for families interested in industrial heritage, engineering history, and scenic landscapes. The site is dog-friendly and requires no entry fee, making it accessible for all visitors seeking to appreciate this significant historical and engineering landmark.
