With its wide skies, rugged coastline, dramatic castles and pretty fishing villages, the stretch of the East Coast Main Line operated by GNER between Durham and Berwick-upon-Tweed boasts some of the country’s most stunning scenery. The medieval magnificence of Durham and the glittering, reborn city of Newcastle are the main destinations for most visitors to the area. But, by taking a short journey out of town, you can completely lose yourself on a beautiful, tranquil beach, with only seals, birds and the occasional fisherman for company.
