Barnes is the village that London absorbed but couldn't quite urbanise. The common, the pond, the village green, the high street with its independent shops — all still functioning as a village in a way that most of London's absorbed villages stopped doing in the 1970s.
The Wetland Centre is the exceptional thing: a nature reserve built on disused Victorian reservoirs, with otter families, regular kingfisher sightings, and winter starling murmurations. The Thames towpath north to Hammersmith passes the Dove pub — the tiny bar, the riverside terrace — before reaching the bridge. It's the best section of the west Thames path.
