A tidal island off Ynys Môn (Anglesey) With an impressive mix of mountain and sea views, the 130-mile Anglesey Coastal Path is a must-do for those who love a good walk. But like most locals, my perennial favourite is the offshoot trail out to the tidal island Ynys Llanddwyn. Having grown up on Ynys Môn but now living in London, for me it has become something of an annual pilgrimage in the summer months. The mile-long walk along the main beach to the island is manageable and fun for grandparents and grandkids alike – with the white-washed lighthouses offering a rewarding end viewpoint. Pack a picnic, swim in the clear waters and relax – just make sure you’ve checked the tide times!
