    Cycling

    Silent Valley Reservoir in the heart of the Mourne Mountains is one of the most beautiful places in Northern Ireland.

    Situated in the Mourne Mountains AONB near Kilkeel, Silent Valley Reservoir not only supplies most of the water for County Down and Belfast, but it is also a beautiful spot to visit.

    Nestled in the heart of the Mournes between Slieve Binnian and Slieve Muck, Silent Valley lives up to its name as one of the most peaceful and tranquil spots in County Down.

    Hiking

    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.
