The DMG area includes spectacular scenery from the ancient Torridonian Sandstones and Lewisian Gneiss. It is popular with hill walkers, containing six Munros and several Corbetts.

Red deer are present on the hills, and roe and sika on the lower ground, taking advantage of the numerous woodland schemes.
