This 14 mile walk will be led by Larry and Margaret with an 8.45 start from Harvey Rd. The start of the walk is from Fulbourn Nature Reserve, with parking at the end of Stonebridge Lane. GR TL526557. If going straight to the start, please be there by 9.00. We will walk the north end of the Fleam dyke and over to Lark Hall corner in the morning, 8 miles with lunch at Balsham, and walk the southern section of Fleam Dyke in the afternoon, 6 miles. We hope there will be some of the chalk speciality flowers flowering for us, so bring your flower books with you.
