Adam , we have been to Holkham beach . It was around 1996 and we were staying in a cottage on The Green in Wells Next the Sea. John ,Jane , Jacob ,Rosie, Florence and I took a picnic down to the beach .It was OK pushing Jane’s wheelchair over the boardwalk, and then it came to an abrupt end and while John and I dragged the chair ( plus Jane …and windbreak,picnic,beach bag etc) over the sand , Jacob ,Rosie and Florence shot off and we were nearly arrested for child neglect .
Beautiful beach though.
You can read whatever paper you want to.
Any other beach recommendations ,a train journey away ?
