Neptune’s Staircase 2017

Neptune’s Staircase at Banavie, near Fort William just north of Loch Linnhe, is kept by Scottish Canals. It is the longest staircase lock in Britain, lifting boats 64 feet (20 m). It consists of eight locks, each 180 feet (55 m) by 40 feet (12 m), and it takes boats about 90 minutes to pass through the system.
