a great castle to explore with views over the se and the Llyn peninsula. It has an informative video that explains its history and then a walk across the bridge that leads you through the fortifications. you can then explore all the rooms that have exhibits of the castles history within them. to finish off you can climb the tower to see the view. Great for kids as there is a park next to it and a cafe across the bridge to keep everyone happy. Parking is available on site but it is a small carpark.

Against stiff competition from Conwy, Caernarfon and Beaumaris, this is probably the most spectacular setting for an Edward I castle in North Wales. All four are recognized as World Heritage Sites. Harlech was completed from ground to battlements in just seven years under the guidance of the gifted architect Master James of St. George. The classic 'walls within walls' design makes optimal use of the difficult natural defenses. Even when the castle was completely cut off by Madog ap Llewelyn's rebellion, it held strong – thanks to the 'Way from the Sea'. Via this path of 108 steps, which climbed steeply up the rock face, the besieged defenders could be supplied with food and drink by ship. Harlech is easier to conquer these days. You can enter this amazing castle via an incredible 'floating' walkway. (Cadw Wales)

Morfa Harlech National Nature Reserve is one of the most important actively growing dune systems in Britain and one of the few in Wales. Dunes like these with bare sandy areas are becoming increasingly rare. This impressive coastal landscape is one of the richest natural treasures and home to a wide range of plants and animals, all specially adapted to life at the edge of the sea.

Stunning viewpoint over Harlech Beach from a footpath leading you to the Wales Coast Path providing direct access to the beach. Harlech Beach offers a pristine four-mile expanse of golden sand, framed by breathtaking vistas of the Snowdonia mountain range and bordered by lush grassy dunes. There’s a flat grassy plateau here, just off the path, for you to sit and admire the sweeping views.
