Why it's Wildland
7.2A three-hectare pocket of wet woodland, ponds and other habitats, enclosed by railway lines and saved from development in the early 1980s.
Gunnersbury Triangle earns its place for the contrast: a compact wildlife reserve tucked into busy west London, where wooded paths, ponds and wetland habitat sit between railway lines. It is a worthwhile short nature break, rather than a destination for a full day by itself.
