1. Turn right out of the car park to the B3098. Turn left, then almost immediately left again up Butts Lane. Fork right into Upper Garston Lane by the Oratory of St Giles then, just before the lane dips, take the path left, waymarked to the church. Descend steps, cross a brook, then climb steps to the church gates. Take the narrow path right and ascend through trees. Ignore the stile on your left and climb the stile ahead into pasture at the base of downland.
2. Follow the permissive path half-right up the field, passing through a belt of trees, then climb diagonally up the scarp slope to the fence at the top. Keep right alongside the fence, go through a gate, then turn right through a metal gate to follow a sunken track around the top of Combe Bottom. At the lane, turn left uphill and soon take the track, right, on to the outer rampart of Bratton Camp. Bear right to follow the outer rampart path to reach the Westbury White Horse hill figure.
3. Shortly, leave the rampart and pass through a gate on to Westbury Hill. Keep to the path, passing benches and a viewpoint pillar, and soon reach a track. Turn left, pass the car park entrance and turn right at the T-junction. Pass White Horse Farm and turn left along the track to join the Imber Range Perimeter Path.
4. Keep to the track for ¾ mile (1.2km) to a barn and take the bridle path left through a gate. Follow the track past a copse into a field and keep to the left-hand edge to a gate. Bear right steeply down a sunken track towards Bratton. Go through a gate and descend through trees and keep ahead on reaching a metalled lane. Turn left at the T-junction, then bear left up a cobbled path (The Ball) between cottages. At the road, keep left back to the hall and car park.
