Happy Valley Park – Chalk grassland nature reserve in Coulsdon with rare wildlife, 24-hour access, and Green Flag Award recognition
Happy Valley Park contains some of the last remaining chalk grassland habitat in Greater London, home to nationally rare plants including the greater yellow rattle and multiple orchid species. The site is a designated SSSI and National Nature Reserve precisely because of this biodiversity. Visitors can explore nature trails to spot these rarities in their natural habitat.
Happy Valley Park ranks among south London's premier nature reserves.

The site's chalk grassland, ancient woodland, and varied geology support exceptional biodiversity.
