Summary:
Landsker is an old Norse word for frontier and the Landsker Borderlands Trail follows part of the original and disputed frontier between England and Wales which is now entirely within Wales itself. So now the route explores the rural area on the Pembrokeshire and Carmarthenshire border from Llanboidy and Efailwen in the north via Canaston Bridge on the Daugleddau to Landshipping and Lawrenny in the south, returning via Reynalton and Ludchurch. The route is shown on Ordnance Survey maps and it is waymarked by a Celtic cross within a brown upright arrow.
