Slieve Donard ( SLEEV DON-ərd; from Irish Sliabh Dónairt, meaning 'Dónairt's mountain') is the highest mountain in Northern Ireland and the wider province of Ulster, with a height of 850 metres (2,790 ft). The highest of the Mourne Mountains, it is near the town of Newcastle on the eastern coast of County Down, overlooking the Irish Sea. It is also the highest mountain in the northern half of Ireland, and seventh-highest on the island.The Mourne Wall – built in the early 20th century – runs up the western and southern slopes of the mountain, joining a small stone tower at the summit. 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. Royal Engineers camped on the summit for four months in 1826 as part of the Ordnance Survey's Principal Triangulation.

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.

The Shimna River flows through the park where it is crossed by 16 bridges, the earliest dating to 1726. The river is a spawning ground for salmon and trout and is an Area of Special Scientific Interest due to its geology, flora and fauna. The forest has four walking trails signposted by different coloured arrows, the longest being the "long haul trail" at 8 miles (13 km) long. It was listed in The Sunday Times top twenty British picnic sites for 2000. The Forest Park has been managed by the Forest Service since they purchased it from the Roden Estate in 1941.

The Glen River flows through the forest where it is crossed by three stone bridges. The north east section of the forest contains a Heritage Stand of Scots and Corsican pine planted in 1927. A south east section, beside the Glen River, was the former site of Donard Lodge. The lodge was built in the 1830s by the Annesley family and demolished in 1966 after falling into ruin. The Annesleys planted a number of exotic trees in the area surrounding the house, including Giant Redwoods and Monkey Puzzles. There is also a small stone shelter, built in 1842, a short distance from the river.

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.
