This is the longest and perhaps most challenging and rewarding walk in the series, allowing walkers to enjoy isolated and remote countryside. There is considerable variety of landscape including woodland, lush meadows and the light terrain characteristic of the Suffolk Sandlings.

Look out for the stone at Blaxhall after which Stone Farm is named. A notice on the garden wall of the house explains its legendary origin (TM 351565). Some of the more remote rights of way are lightly used and may not be as evident as those nearer villages, so the use of the 1:25,000 Explorer map will be helpful.

Route finding - key points (numbers refer to points on the route diagrams)

1. From the station go left past the pub to road junction. Take Loudham Road and left into Ullswater Road.
2. Beyond the last house the path goes off right by the railway. Follow for about 200m, then cross the line.
3. Branch left on the field edge path by Barnes's Grove.
4. Go down the driveway to Ashgreen Farm, then take long track beyond to sharp left turn to road.
5. Take the path on the right for 300 yards, then go left at the side of the wood.
6. From the corner of the wood go half right, across grass field, then left along farm track.
7. At the approach to the farm turn sharp right opposite the field gate along a broad track passing below cables.
