Mount Piddington is a mountain located 1.5 kilometres south of the Blue Mountains village of Mount Victoria. The Mount Piddington Lookout is on the southern section of Mount Piddington. There are restrooms and a picnic area at its summit, surrounded by a loop road, Mount Piddington Road, which runs from the summit to Mount Victoria village. It is also the starting point of several bushwalking tracks that descend to the cliffs of Hornes Point and the Fairy Bower reserve. Notable sites on the slopes of Mount Piddington include Coxs Leap and Bushranger Cave.

Views of the Kanimbla Valley are possible from the lookout, although trees are present and are not entirely clear. The mountain is mostly covered in the bushland of the Eucalypt variety and adjoins One Tree Hill (1,111 metres) the highest point in the Blue Mountains Plateau.
