Hadrian’s Cycleway, United Kingdom It is a wild coast-to-coast ride along the northern boundary of the old Roman Empire, with low hills that don’t rise above 250m. The rich heritage of Cumbria, the rugged beauty of Northumberland and the Roman forts of Birdoswald and Vindolanda en route are vivid lessons in ancient history. We recommend the 135-km coast-to-coast section, from Carlisle to Newcastle, which has the best scenery and is the easiest to get to. Be the first to spot the ‘Blinking Eye’ bridge in Newcastle and get a well-deserved pint of local ale at Corbridge.
