Petershill is located to the north east of Bathgate. It was a limestone quarry during the 18th Century and converted into a reservoir in the 19th Century, before being drained in 1986. It now includes areas of species-rich grassland, scrub and wetland, and is also an important geological site.
From Junction 3a on the M8, follow directions for Bathgate until a roundabout is reached where the B792 (Kirk Road) is taken north west until a T-junction. Turn right at the T-junction and follow Drumcross Road eastwards and up the steep hill out of Bathgate. At the top of the hill there is a sharp bend, after which there is a small parking area on the left. Visitors are asked to park responsibly and not restrict access either to the working farm or farmers' fields at Petershill.
From the parking area, a path leads into the reserve.
Park in the designated parking area on the east side of the reserve, taking care not to obstruct access either to the farm or to surrounding fields. Please do not park on the farm track that runs along the western edge of the reserve.
