Leaving the Union Bridge and it's into England, and Northumberland, England's least densely populated county. Northumberland has its own National Park, dozens of castles and fortifications, Hadrian's Wall, and at Kielder, the largest man-made lake in Western Europe set in the UK's largest man-made forest. Northumbria's Cycling Kingdom route encounters all except for Kielder, which is available via the Reivers Cycle Route.
