Belsize Wood

Belsize Wood is a 0.7 hectare Local Nature Reserve and a Site of Borough Importance for Nature Conservation, Grade II, in Belsize Park in the London Borough of Camden. It is a steeply sloping site divided into a northern half, which is always open to the public and is of lesser ecological value, and a southern part which is in a better state of conservation, and which is only open at weekends. The two halves are separated by a public footpath between Lawn Road and Aspern Grove. The site is owned and managed by Camden Council.
