Takes its name from the River Loop, which passes through this part of East Belfast. Its feeders, Merok Burn and the Glen Burn in Cregagh Glen, rise on the steep ground of the Castlereagh Hills. Reaching the plain, it slows and begins to meander somewhat, a feature which gives the river its name. It is particularly prone to flooding in this middle section in the vicinity of Ladas Drive. It then joins the Knock River to form Conn's Water, which flows to the sea.
