York The most intact medieval city in England. The Shambles, York Minster (one of the largest Gothic cathedrals in Northern Europe), and the Roman walls you can walk in their entirety. The Viking history is layered underneath: the JORVIK Viking Centre is more serious than its name implies.
Whitby A dramatic Abbey ruin on the cliff above a fishing harbour — the landscape that inspired Bram Stoker to set part of Dracula here. The 199 steps, the narrow streets of the old town and fish and chips consistently ranked among the best in England. Go in autumn when the light is extraordinary.
Liverpool The UNESCO-listed waterfront, the Three Graces and the Liverpool Museum — which tells the story of the port that connected the British Empire to the world, including the Atlantic slave trade. The Beatles Story is better than you'd expect. The city's architecture, food scene and nightlife are underrated relative to Manchester.
The Peak District England's first National Park. Chatsworth House (with gardens by Capability Brown), the gritstone edges of Stanage and Froggatt, the limestone dales (Dovedale, Lathkill Dale), and the market town of Bakewell, where the pudding was originally made — distinct from the tart.
The Lake District Wordsworth's landscape, and you understand why he never left. Windermere, Grasmere, Coniston and Ullswater are each distinct in character. Scafell Pike and Helvellyn are serious walks but accessible to fit non-climbers. Go in October for the colours and the relative quiet.
Durham Chronically undervisited. Durham Cathedral — Romanesque, on a cliff above a river bend, containing the tombs of St Cuthbert and the Venerable Bede — is one of the finest buildings in England and far less crowded than comparable cathedrals. The market town below is ordinary; the peninsula above it is not.
Northumberland The least densely populated county in England. Hadrian's Wall crosses it east to west; the coast has Bamburgh Castle on a basalt outcrop above white sand and the Farne Islands (puffin and grey seal colonies). The Kielder Dark Sky Discovery Site is the largest area of protected night sky in England.
