The Welsh Shore - Ancient and Modern, from the ruins of Flint Castle to modern Business Parks. Cut off for much of its length by the Chester to Holyhead railway the estuary manages to be remote and largely undisturbed despite the adjacent towns and industry. Here the Dee Estuary is bordered by the Welsh hills, whose valleys are filled by woods full of birds and wonderful walks.

The five main birdwatching areas covered are Shotton and Connah's Quay, Bagillt and Flint, Greenfield and Fynnongroyw, Talacre and Point of Ayr, and Gronant.
