In the past I used to ride to Hexham on my road bike from North Tyneside but, now I mainly ride a gravel bike. I miss riding to Hexham but I cannot find a route there mainly offroad. I've tried planning a route along the River Tyne but can only get as far as Prudhoe before it mainly turns to road. Any ideas?
I suspect there isn't one.
As you know, the few miles from Prudhoe on minor roads on the north side is quite agreeable cycling, not least because the majority of motor traffic is on the nearby A69.
Some caution needed on the downhill approach to Corbridge, although some attempts have been made to make it more cycling friendly with road markings.
Last time I was there, the marked vehicle/cycle lanes had been redrawn again, which is another reason to take it steady at least until you've been through once to check the layout.
