Northumbria is home to the loneliest stretches of moorland and coast in the country. The region has much to offer the nature lover, walking enthusiast, history buff, gastronome and gardener: rare wildlife, Georgian architecture, the Pennine hills, Hadrian's Wall, Alnwick Gardens and Alnwick Castle, featured in the Harry Potter films. Gemma Hall shares her love of Northumberland, Durham and Tyneside, guiding visitors through historic towns, cities and villages; across the Cheviot Hills and along Northumberland's Heritage Coast; to outdoor swimming spots, high altitude flower meadows and the wooded gorges of the Durham coast.
