Slieve Corragh (SLEEV KORRA; from Irish Sliabh Corrach, meaning '"rugged/pointed mountain" or "sheep hill"') is one of the Mourne Mountains in County Down, Northern Ireland. It has a height of 640 metres (2,100 ft).

Slieve Commedagh (from Irish Sliabh Coimhéadach, meaning 'the guarding/watching mountain') is a mountain with a height of 767 m (2,516 ft) in County Down, Northern Ireland. It is the second-highest of the Mourne Mountains, after Slieve Donard, and the second-highest mountain in Northern Ireland. Slieve Commedagh lies to the northwest of Slieve Donard, and the two are linked by a col. The Mourne Wall passes east–west over the mountaintop, and there is a small one-room tower at the summit. There is also the remains of an ancient burial cairn on the summit. On its southern side is a group of granite tors known as 'the Castles'.The Slieve Commedagh massif also includes the summits of Slievecorragh (to the east), Shan Slieve, Slievenamaddy and Slievenabrock (to the north).

Slieve Lamagan or Slievelamagan (from Irish Sliabh Lámhagáin, meaning 'mountain of crawling/creeping') is one of the Mourne Mountains in County Down, Northern Ireland. It has a height of 702.2 metres (2,304 ft). Slieve Lamagan stands in the middle of the high Eastern Mournes, overlooking Ben Crom Reservoir to the west, Annalong River valley to the east, and Cove Mountain to the northeast. 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. An older name was Slieve Snavan, from Sliabh Snámháin, which has the same meaning.

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.

Bryansford is a small village in County Down, Northern Ireland. It sits at the northern side of Tollymore Forest Park, roughly halfway between the towns of Newcastle and Castlewellan. The village is within the townlands of Ballyhafry and Aghacullion, in the Civil parish of Kilcoo. It had a population of 392 people in the 2001 Census.

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.

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.

Annalong Forest is located near the village of Annalong in County Down, Northern Ireland. It is made up of two sections: Annalong Wood and Silent Valley. The forest consists of various species of conifer. It is part of the Mourne Area of Outstanding Natural Beauty. There have been two major forest fires in the area since 2011. One, which started on 30 April 2011, required 10 fire engines to extinguish and caused the temporary closure of several roads. Another, on 24 April 2010, destroyed approximately 50 hectares of gorse and was believed to have been started deliberately.

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.

Ben Crom (from Irish Binn Chrom, meaning 'curved/stooped peak') is a 526 metres (1,726 ft) mountain in the Mourne Mountains in County Down, Northern Ireland. It is situated beside Ben Crom Reservoir, which is upstream from Silent Valley Reservoir. The mountain is composed of granite. An exposed area on the south west of the mountain shows where the Eocene aplitic granite meets the laccolith top of the older Mesozoic granite ring dike. The summit of the mountain features granite crags which are crossed by basic and feldspar porphyry dikes. The mountain is used for sheep grazing and hill walking.

Tollymore Forest Park was the first state forest park in Northern Ireland, established on 2 June 1955. It is located at Bryansford, near the town of Newcastle in the Mourne and Slieve Croob Area of Outstanding Natural Beauty. It covers an area of 630 hectares (1,600 acres) at the foot of the Mourne Mountains and has views of the surrounding mountains and the sea at nearby Newcastle. 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.
