Narrowboating in the UK involves cruising on canals and rivers in long, slim boats called narrowboats, which are designed to navigate the narrow locks of the UK's canal system. These boats are a popular way to explore the UK's waterways, offering unique holiday experiences and a slower pace of life for those living on board.

Narrowboats are specifically designed to fit the narrow locks of the UK canal system, typically measuring less than 7 feet (2.13 metres) wide. They are known for their elongated, slim profile and are often ornately decorated, especially those used for leisure. Modern narrowboats are usually made from steel and powered by diesel engines, though older boats may be made of wood.

Narrowboating holidays are popular for their scenic routes, peaceful atmosphere, and opportunities to explore the UK's countryside at a slower pace.
