A lovely spot for a picnic or a rest. The carvings sit just off National Cycle route 7, and at a junction connecting the Castle Semple Lochside Trail with Parkhill Woods.

Decent surface following the old railway cutting. The section around Lochwinnoch tends to get busy with pedestrians at the weekend.
