Wandle Park is off Merton High Street, Colliers Wood. The park lies alongside the river Wandle, an area rich in early industrial history, and is of informal design with woodland and wetland features. It occupies approximately 11 acres and is situated on the site of a former millpond.
The site is bounded by Byegrove Road, Merton High Street and the River Wandle. Public access is via Millars Mead Court, Baltic Close, behind flats along Byegrove Road and across the footbridge along the River Wandle. The main vehicle access is by the old lodge.
