Site details


These commons cover 800 acres of predominantly heathland situated on either side of junction 10, joining the M25 motorway to the A3. There is a footbridge over the A3 that connects the two commons. Situated near to the famous RHS Wisley Gardens, the commons are a beautiful landscape and open space to get away from it all. Chatley Heath forms part of the commons.

As well as beautiful natural habitats such as Bolder Mere Lake and the wildlife that visits, there are also some interesting man-made features. Built in 1822, the historic Semaphore tower sits at Chatley Heath on the south-east side of Ockham common. Hidden in the woodland close to this is the Samuelson Mausoleum, built in 1919 by Sir Henry Samuelson to be a 'Temple of sleep' for his family. We acquired the building and surrounding land in 1992.

Please take care of our countryside and open spaces, particularly areas of heathland where fire risk is high and follow the Countryside Code.
