Cobham Wood is 165 acres of restored wood pasture located within Historic Cobham Park, and is home to the Grade I listed Darnley Mausoleum, originally completed in 1786 as the intended resting place of the 3rd Earl. Since late 2005, the landscape has been extensively restored as part of the wider Cobham Park Heritage Project.

Visitors can see many fine examples of veteran oak, hornbeam and sweet chestnut trees, many of the latter planted by the renowned landscape architect Humphry Repton 200 years ago. Visitors can also experience stunning views of the Thames Estuary, the North Downs, and the Elizabethan Cobham Hall (now a private school). The Mausoleum is of course a particular highlight. The painstaking two year programme of restoration is now nearing completion, and the results are spectacular.

Neglected for decades, Cobham Wood was once the scene of widespread joyriding and vandalism and the combating of this over the last ten years is a major success story. More recently, work as part of the Heritage Project has involved the selective thinning of scrub and young trees -particularly invasive sycamore - and the wood pasture habitat is being fully restored with the reintroduction of grazing cattle to manage the vegetation. In addition, new permissive access routes are being installed, both within Cobham Wood, and linking into the wider area.

Cobham Wood is also part of the larger Cobham Woods Site of Special Scientific Interest, which includes the neighbouring Ranscombe Farm Reserve. Ownership of Cobham Wood and the Darnley Mausoleum will transfer to the National Trust in September 2008.
