Swanley Bridge Marina is a family-run narrowboat marina situated at the start of the Llangollen Canal in Swanley, near Nantwich, Cheshire.

Founded in 2006, it sits close to the junction of the Llangollen Canal and the Shropshire Union Canal, placing it within easy reach of the broader North West canal network.

The marina offers a concrete slipway (rated Grade 1a) available by prior arrangement for day use or longer cruises. Services on site include boat servicing and repairs, narrowboat engineering, hull blacking, grit blasting, and narrowboat haulage.

It serves as a popular base for cruising the 46-mile Llangollen Canal, which passes the Pontcysyllte and Chirk aqueducts — part of a UNESCO World Heritage Site.
