[1] Atop Watership Down, which is exposed and windswept, lies a Beech tree planted in memory of Richard Adams.
Other nearby features include Ladle Hill, on Great Litchfield Down, immediately to the west.
Part of the hill is a 10.37-hectare (25.6-acre) biological Site of Special Scientific Interest, first notified in 1978.
The hill has a partially completed Iron Age hill fort on its summit, and the surrounding area is rich in Iron Age tumuli, enclosures, lynchets and field systems.
Watership Down Stud is a horse-breeding establishment owned by Andrew Lloyd Webber and his wife Madeleine Gurdon, a former eventer, who live nearby at Sydmonton Court.
