The walk

Follow the reservoir road from Silent Valley towards Ben Crom, then return the same way. The 10 km outing needs stamina even though it follows the road.

Underfoot

The walk follows a tarmac road. Allow for the full return distance; the route stays below the mountain summits.

Start & access

Start: Silent Valley Mountain Park, Head Road, Kilkeel, BT34 4HU.

Use the main Head Road gates. Check NI Water's admission, hours and access notices before travelling. Follow current signs and barriers.

Route map & access at NI Water — Silent Valley Trails

Give yourself enough time

Allow for your group’s pace, terrain, stops and daylight. Leave enough time and energy for the return journey.
