The London Borough of Camden is in percentage terms the second-greenest of the Inner London boroughs (based on public green spaces). It contains most of the swathe of land Hampstead Heath and many smaller green spaces. The Central London part of the borough, south of Euston Road, is characterised by its elegant garden squares with large instances: Tavistock Square and Bedford Square. In this part runs the Regent's Canal (a 'Green Route') around the top edge of Regent's Park, a little of which is in Camden, including all of associated Primrose Hill. Highgate Cemetery is in Camden but Highgate Wood is in the neighbouring borough of Haringey.
