Deep Dale is a short ,steep-sided gorge near Buxton, Derbyshire, in the Peak District of England.

They discovered Roman artefacts, including bronze jewellery, enamelled brooches, pottery fragments, coins and an iron and bone knife.

[2][3]Deep Dale and Topley Pike is a protected nature reserve, which is overseen by the Derbyshire Wildlife Trust.

The reserve contains whitebeam, yew, ash and hazel trees and limestone fern on the lower scree slopes, with bilberry, cowberry and wild flowers on the steep upper slopes, including bloody crane's bill, clustered bellflower, rock rose and Nottingham catchfly.

It was opened in 1907 by Messrs. Newton Chambers & Co. and is currently operated by Tarmac Roadstone Holdings Ltd. A drystone wall runs along the length of the floor of the dale and marks the boundary between the mining rights of Buxton Mining Liberty and the Combined Liberty of Taddington, Flagg, Monyash and Upper Haddon.

The footpath through the lower section of Deep Dale is closed from 2017 until 2025 for natural restoration, following the removal of a large spoil tip (waste from the quarry).
