At its southern foot is a small lake called Blue Lough, and a rock formation known as 'Percy Bysshe' .It is said that the mountain was named Sliabh Lámhagáin, "mountain of crawling/creeping", because its steepness meant it had to be climbed in a crawling position.

Also on the summit are the remains of two ancient burial cairns, one of which is the remains of the highest known passage tomb in Ireland. In Irish mythology the mountain was associated with the mythical figures Boirche and Slángha. It was later associated with, and named after, Saint Donard, who was said to have made the summit his hermitage. Up until the 1830s, people would climb the mountain as part of a yearly pilgrimage, which may have originally been a Lughnasadh (harvest) ritual.

Ben Crom Reservoir is a reservoir located in the Mourne Mountains near Kilkeel, County Down, Northern Ireland. Along with Silent Valley Reservoir, which is situated further down the Kilkeel River valley, it supplies water for County Down, surrounding counties and most of Belfast. It was constructed between 1953 and 1957, as the final part of the Mourne scheme to provide water to Belfast which started with the passing of the Belfast Water Act in 1893.Ben Crom is a mass gravity dam, meaning it is made of concrete and designed so that the dam's own weight stabilises it against the force of the water. The middle of the structure consists of mass concrete with granite plumbs weighing up to 5 tonnes. The outer face of the dam was made with precast concrete blocks. The project cost approximately £1 million to build and employed 186 people.In 2012 Northern Ireland Water carried out refurbishments at Ben Crom as part of a £1.6 million scheme to maintain and improve a number of reservoirs in Northern Ireland.

Glen River is a short river in County Down, Northern Ireland. The two-mile (3.2 km) course flows north-east from the foot of Slieve Commedagh and Slieve Donard in the Mourne Mountains into Dundrum Bay at Newcastle, descending 1,500 feet (460 m).It is quite a fast-flowing river with many small waterfalls and deep pools. The bedrock is composed of granite in the upper parts, becoming dark shale lower down. It flows through Donard Forest and Donard Park and is crossed by five bridges. The path that runs alongside the river is commonly used by walkers climbing Slieve Donard.There is an unusually prominent ice house beside the river, just before it enters the forest. It was built by the third earl of Annseley in the 1830s to serve his Donard lodge residence.

Millstone Mountain is a hill in the Mourne Mountains in County Down, Northern Ireland. It is the most easterly peak in the Mournes and, along with Thomas Mountain and Crossone, is one of the three subsidiary peaks of Slieve Donard.Millstone was produced in the area in the past and there are two former sites to the south-west and north-west of the summit. A granite quarry was opened on the northern side of the mountain in 1824 and a funicular railway, known as the Bogie Line, ran from it to King Street. The railway was diverted to the nearby quarry on Thomas Mountain in 1959. Both quarries are abandoned and the path of the Bogie Line is now a walking trail known as The Granite Trail.

Slieve Bearnagh (from Irish Sliabh Bearnach 'gapped mountain') is one of the Mourne Mountains in County Down, Northern Ireland. It has a height of 739 metres (2,425 ft). Its summit is crowned by two tors with a gap between them, giving it a distinctive shape. The Mourne Wall crosses the summit of Slieve Bearnagh east to west. Paths lead to the cols on either side of the mountain, namely Pollaphuca ("pool of the púca") to the west and Hare's Gap to the east. From the latter, one can also descend southwards to the head of the Ben Crom reservoir.
