Densely forested with eucalypt, the Jamison Valley stretches north-south from Katoomba to the Coxs River. It is approximately 12 kilometres long and stretches some 10 kilometres east to west from Narrow Neck Plateau to Kings Tableland.
It forms part of the Cox River system in the Blue Mountains of NSW and is approximately 100 kilometres west of Sydney. Like the entire Sydney and Blue Mountains region, the valley is a sandstone area, characterised by steep sandstone cliffs.
The valley contains many popular bushwalking trails and attractions include many spectacular waterfalls – Wentworth Falls, Empress Falls, Vera Falls, Gordon Falls, Leura Falls and Katoomba Falls.
