[1] Radnor Gardens is located 0.5 miles (0.80 km) south of Twickenham town centre between the A310, Cross Deep, and the Thames riverbank.

It affords one of the few pedestrian points of access to the river on the Middlesex bank between Twickenham and Kingston Bridge.

The course of the former channel can be discerned in the lawns during dry weather and metal remnants of connecting footbridges can be perceived lining the central and southern footpaths in the gardens today.

Twickenham War Memorial by Mortimer Brown was erected in 1921, which, despite facing south, was sited to form a focal point of a vista from the Royal Star and Garter Home on Richmond Hill to the north-east.

[6] The gardens are administered by Richmond upon Thames Borough Council and form the southern limit of the Twickenham conservation area.
