Directions to Cairn Hill (Cairnryan): My route starts at Cairnryan Village Hall, adjacent to P&O Ferry Terminal. Park up at Cairnryan Village Hall. Walk N for c. 300 yards, cross the grass onto Claddyburn Terrace. Take the private single track lane to High Croach that bears left from Claddyburn Terrace. Follow this track uphill for c. 0.9 miles to NX 0796 6846. Turn left into a gateway heading W towards a gate in corner of the field. Head W along the dry stane dyke for c.140 yards to reach a gate into a rough pasture field. Walk c. 170 yards WSW towards a gate in the field. In the next field head WNW for c. 130 yards to another gate leading into a large field. Proceed NNW for c. 650 yards to a gate in the NW corner of the field. A 4x4 track heads NW into a boggy area turning W towards the grassy summit of Cairn Hill. There is a trig point on the summit. The remains of the cairn are a low grassy mound c. 15 yards ESE of the trig point. My route is viewable on Cairn Hill (Cairnryan) Cairn.
Once you leave the road the route may be boggy so waterproof footwear is recommended.
