As you make your way out of Winchester towards Crab Wood past the wooden carving on your right you will find a well used vechicle stoping point (lay-by). From the lay-by, follow the well trod footpath to a large, Y shaped, ivy covered tree. The cache you seek is behind the tree near the base among the ivy vines.
