Free camping at Stibbington
Where the truckers’ ‘diner’ is situated. About a mile after the main junction with the A47 (bridge over the road). You might find it somewhere here.
Free camping around Water Newton
Just before the signs for East of England Showground and Alwalton, there is a bit of old road which sometimes has a cafe in it during the daytime. It’s shielded from the road by a belt of trees, but there is usually a somewhat ramshackle ‘Cafe’ sign.
