Tips

Silent Valley Reservoir, nestled in the Mourne Mountains, is a peaceful retreat surrounded by sweeping granite peaks and heathered slopes. Built in the early 20th century to supply water to Belfast and much of County Down, the reservoir combines striking engineering with natural beauty. Visitors can stroll along well-kept paths, admire the Victorian-style dam and impressive Mourne Wall, or simply enjoy the quiet atmosphere by the lakeshore.

Silent Valley Reservoir marks the first point of interest on the sensational Mourne Wall Challenge. Enjoy dazzling views across the still waters and up to the mountaintops of the Mournes.
