Project description

Happy Valley is Croydon Council's largest open space and, together with the neighbouring Farthing Downs, comprises the largest area of chalk grassland within Greater London. It is home to important plant and invertebrate species, including 12 species of orchid and most of the UK's population of Greater Yellow Rattle. There is an important ancient woodland, home to a population of hazel dormice.

The objective is to create a balance between management for public amenity and nature conservation, fulfilling the needs of visitors while protecting a nationally important wildlife site.

We encourage visitors from a diverse range of backgrounds, ages and abilities, including from within the more urban areas of the capital.

Our QR audio nature trail, narrated by celebrities like Joanna Lumley, Tony Robinson, and Benjamin Zephaniah, alongside a diverse range of volunteer speakers offering translations in Hindi, Polish, and French, brings nature to life for everyone.

Project location

Happy Valley is located on the southern edge of London, on the border with Surrey. It offers a great opportunity to engage with a large population, including those with limited access to high quality greenspace.

Contribution to Big Chalk

The ongoing management of the Happy Valley SSSI/NNR, coupled with meaningful engagement with a diverse range of visitors and local people, fits well with Big Chalk’s vision.

Happy Valley is a proposed addition to the Surrey Hills National Landscape and there are plans to create a Green Community Hub on site.
