Walk up the road from the beach car park and keep left at the junction. When the road bends, turn left on to a footpath that climbs through the woods to the ruins of Greyfriars Friary. Follow this path, ignoring turnings off, then go under an arch and come out onto a track that leads to a road.

Turn left along the road then turn left off it after 100yds (91m) on a track to the Dairy House. Keep straight ahead on this path as it enters Greyfriars Wood and continues to a road.

Turn left and walk along this road for 0.5 mile (800m), passing two caravan sites on the left. As soon as you enter National Trust land, turn left on to a path, ignoring the path off towards the cliffs soon afterwards. 

Walk around the National Trust's Coastguard Cottages and take the track beside Heath Barn field centre, then bear right on to a sandy path that climbs through the heather. Keep on this path, bearing left and right at a crossing track to follow the Sandlings Walk nightjar waymarks. When you reach a bridleway, keep straight ahead on a farm track passing Mount Pleasant farm. Cross the road and keep straight ahead on a gravel and grass lane to Sandy Lane Farm.

Turn right for 0.5 mile (800m) on a shady bridleway to emerge by St James's Church, built in the 19th century when Dunwich's other churches were falling into the sea. (For a short cut, keep straight ahead here to return to Dunwich.)

Turn left at the road and, in 100yds (91m), go right at Bridge Nurseries and Café. Keep to the right around the farm buildings and stay on this track for 1.5 miles (2.4km) beside Dunwich Forest before turning seawards. Pass through a gate to enter a covert and fork right at a junction just before     Great Dingle Farm, then follow the path through the reed beds and a gate towards the sea.

Turn right at a junction when you see an old drainage mill to your left, and follow the flood bank across Dingle Marshes. Turn right to return to Dunwich along the beach or take the path behind the shingle bank.
