Bourley and Long Valley is a 823.5-hectare (2,035-acre) biological Site of Special Scientific Interest between Fleet and Aldershot.
The area comprises a range of habitats, including pine and mixed forest, heathland, open scrub, and wetlands. It supports a rich fauna, with birds and invertebrates being of particular (national and European) importance.
It also includes the large multivallate Iron Age hill fort known (erroneously) as "Caesar's Camp". This impressive structure covers 10.5 acres. Excavation has shown it was built in three phases, and was reused in the mediaeval period as a park pale (a boundary used to retain deer). The hill fort is of national archaeological importance. The north eastern ridge of the fort provides excellent views over Hampshire and Surrey.
Although most of the land is owned by the military, for most of the year there is public access. There are a number of excellent paths and tracks, which are very popular for cyclists, walkers, and those exercising their dogs. The lakes formed from former reservoirs are particularly scenic. However, bathing is not allowed and fishing access is controlled. read more
