Meet at Hunter's Supermarket, Mowhan Road in Markethill. Supermarket is on your right hand side opposite PSNI Station and Cattle Mart just after the roundabout at the bottom of the main street and Mowhan Road is a continuation of the main street. Even if you are going direct it is suggested you meet at Hunters for toilets and car share as car parking at Ballymoyer is limited.
Leaving Markethill continue south on the Mowhan Road (B78) to Whitecross and turn right as you enter the village at crossroads on the Ballymoyer Road (signed Newtownhamilton). After about half a mile you will come to the first road on your right (Drumcrow Road) and the Ballymoyer car park is immediately after this. Drumcrow Road will give you a more direct return route to Markethill and home, cutting out Whitecross but, at the start at least, it is a narrow winding road with few passing places.
If you use your satnav the postcode above will take you close to but not necessarily right up to the woodland.
