The area ranges in elevation from around 225 metres to 475 metres, and includes two hills, Toot Hill () in the east and Nessit Hill () in the south. Within the forest are two reservoirs, Trentabank () and Ridgegate (), which are fed by Bollin Brook. They are the highest of a series of four reservoirs, the lower two being the Bottoms and Teggsnose Reservoirs, south of Tegg's Nose.
