Mangerton's western slopes lie within the Killarney National Park. On Mangerton's north-western face lies a deep corrie lake called the Devil's Punchbowl, which is a popular scenic destination for hill walkers; although the mountain is often overlooked by walkers due to the proximity of its more scenic and accessible neighbour, Torc Mountain.
