A half-term escape to the sea. Not just any sea but the North Sea which had been calling me all summer. So we boarded the train at Stratford bound for Frinton-on-Sea and walked along the coast, past beach huts piled high along the seafront, to Walton-on-the-Naze. Reaching the Naze Tower on the crumbling coastline, Felixstowe in view to the north, we turned and headed back for the early evening train back to London.
