Bingley Five-Rise Locks is one part of a series of eight staircase locks in two flights on the Leeds & Liverpool Canal near Bingley Station. It is the steepest lock flight in the UK.
The five-rise locks are set up in such a way that the top gate of one forms the bottom gate of the next. They were built by local stonemasons and raise the canal level by 18m over a distance of 97.5m. They allow passage for vessels up to 22m long and 4.3m wide.
The first boat to complete the journey down through the five locks, on 21st March 1774, took just 28 minutes.
To travel up the flight, the bottom lock must be empty with all the others full. To descend the top lock must be full and the other four empty. The journey through the staircase can take up to 90 minutes.
The locks are closed at night. They are situated in a valley parallel to the River Aire. After traversing them, there is almost 26km of lock-free canal to enjoy.
