Headley Ford
About 2.2 miles (Enborne 1.0 + Acland 1.2).
Enborne 1.0 miles plus Acland 1.2 miles, total 2.2 miles. A lovely stretch by the River Enborne. About a quarter of a mile of road walking at the Headley Ford end.
Parking
Well, the parking is difficult at Headley Ford. I get the impression that someone has decided that "They" don't want people enjoying themselves at this beautiful location. The road is often marked "CLOSED" which could deter some. Locals who have enjoyed many a hot sunny day playing in the ford may not be so easily put off. Pin 51.371804, -1.253729.
