Oxleas Wood is one of the few remaining areas of ancient deciduous forest in the Royal Borough of Greenwich (with a small amount passing over the boundary into the London Borough of Bexley), in southeast London. Some parts date back over 8,000 years to the last Ice Age, the Younger Dryas. It is part of a larger continuous area of woodland and parkland on the south side of Shooter's Hill: other parts are Jack Wood, Castle Wood, Oxleas Meadows, Falconwood Field, Eltham Common and Eltham Park North (the latter being divided by the A2 main road from its southern section). Eltham Park North includes the ancient Shepherdleas Wood.
Oxleas Wood, Jack Wood and Shepherdleas Wood are a Site of Special Scientific Interest called Oxleas Woodlands, covering 72 hectares with oak, silver birch, hornbeam, coppice hazel, and a great number of fine samples of the Wild Service Tree. A larger area including Eltham Common is designated a Local Nature Reserve called Oxleas/Shooters Hill Woodlands.
The site covers most of the top of Shooters Hill (in the Royal Borough of Greenwich), and contains a folly called Severndroog Castle. There is an underground water reservoir in the grassed area called Oxleas Meadow. This serves the local area with water. This is associated with 'the hut' which is a building containing the equipment that Thames Water uses to control the reservoir.
Within Oxleas Meadow is a cafe. The café building is of brick construction and is owned by the Borough of Greenwich. Public male and female toilets are also located in this building and are available for use during the café opening hours. The café part of the building is leased to the café operator.
There have been plans to build roads through Oxleas leading to a Thames Gateway Bridge over The River Thames as part of the Thames Gateway redevelopment plans. These plans were abandoned in 1993 after strong local protests. The proposals for the Thames Gateway bridge have recently been revived and there is concern that, if built, this would lead to pressure to link it to the A2, crossing Oxleas.
