Willowtree Marina sits on the Paddington Arm of the Grand Union Canal in West London, within the London Borough of Ealing.

It serves as a well-established base for residential, leisure, and pied-à-terre moorings, offering boaters a combination of accessibility, security, and attractive surroundings.

The marina provides a range of practical facilities including electric and water points, a pump-out station, fuel and gas supply, toilet and shower facilities, a laundrette, refuse disposal, a car park, and 24/7 CCTV security.

It also functions as a venue for filming, canal events, wildlife photography, and towpath walking. An on-site restaurant and bar, Lock & Quay, adds to its appeal as a destination on this stretch of the Grand Union Canal.
