Harlech Castle in North Wales is a top summer destination, combining a well-preserved medieval fortress with a four-mile sandy beach. The castle sits atop a rocky crag overlooking the Morfa Harlech National Nature Reserve and Harlech Beach, with the rugged peaks of Eryri (Snowdonia) as a backdrop.
Beach and Nature Highlights
Harlech Beach is a designated National Nature Reserve and Site of Special Scientific Interest due to its unique dune system, according to the UK Beach Guide. During summer, leatherback turtles migrate to this coast to feed on jellyfish. In 1988, a record-breaking 916kg leatherback washed up here after becoming entangled in fishing equipment. The beach is popular with families and dog walkers and tends to be less crowded, offering a relaxed seaside experience with castle views.
Visitors should bring supplies, as the beach has no shops or ice cream stalls. A shop and café are located near the railway crossing, and dining options include Caffi Castell Harlech, The Plas Restaurant, and Caffi Llew Glas. There is no lifeguard service, and strong offshore currents exist, so swimming is advised with caution.
Castle History and Architecture
Built between 1282 and 1289 by King Edward I's chief architect, James of St George, Harlech Castle cost £8,190. It is part of a UNESCO World Heritage Site, noted for its double-wall concentric structure and beautiful proportions. The castle features a massive gatehouse that once housed the constable and dignitaries. Its 'walls within walls' design withstood sieges, including the rebellion of Madog ap Llywelyn (1294-95) and fell to Owain Glyndŵr in 1404, who used it as his residence until 1409.
During the Wars of the Roses, Lancastrians held the castle for seven years until 1468, a siege commemorated in the song 'Men of Harlech'. The tune is now chanted at Welsh sports matches. In the English Civil War, Harlech was the last royalist stronghold to fall in 1647.
