The distance involved makes this a challenging walk, however it is most rewarding and full of interest.

Follow the good track between Sundown Valley and Dow Hill. This hill and moorland route branches off to Dalfask Farm and Pinmore. The route passes close to Dinvin Motte reputed to be the finest prehistoric fort in Ayrshire. It is situated on a dominating ridge just north of Pinmore. It consists of a central mound and defended by two well defined circular ramparts and ditches.

Just below Dinvin is the 496 metres long railway tunnel on the Girvan Stranraer line, built in 1877. The route now lies from Pinmore down the quiet valley of The Water of Lendal. On a rough moorland path the route skirts the Grey Hills, a wildlife reserve managed by the Scottish Wildlife Trust. Special features are patches of herb-rich turf situated on outcrops of Serpentine rock, only to be found in four other localities in the British Isles.

From the path you look down on Loch Lochton where there is a fine display of both white and yellow water lilies. There are magnificent views over the surrounding countryside on your return.
