This is the lower of two peaks in the Mourne Mountains called Slievenaglogh, the other being situated further north near Hare's Gap. This Slievenaglogh overlooks the Silent Valley Reservoir, constructed in the 1920s to supply water for Belfast. Before it was flooded, the Silent Valley was known as the 'Happy Valley'. Labourers from the Happy Valley constructed the Mourne Wall for the Belfast and District Water Commissioners to delimit the catchment area. It is 2-2.5m high and 1m thick, encloses 9,000 acres of land (3,600 hectares) and passes over the summit of many of Mourne's highest peaks.   Slievenaglogh is the 748th highest place in Ireland.

Walls prove an excellent navigation aid.
Short Summary created by Colin Murphy  16 Jul 2020
Simplest place to start is the Bann's Road Car Park, which can accommodate about 8 cars. Follow the Banns Road (which is really just a decent stoney track) north for about 1.5km until you reach a gate/stile. Turn east and follow the gently ascending wall for 800m until it intersects a second wall heading NE. This will take you all the way to the summit, which is a mostly grassy/heathery area with a small cairn marking the high point. The final 300m is very steep and rocky and requires a little scrambling. Magnificent views over the Ben Crom and Silent Valley reservoirs.
