Northumbria,Cheviots and Kielder water

Hi all, Im a newbie to the forum and wondered if anyone knows of some good lanes around these areas ?

We have been laning for a few years now,but have just changed to a 90' and will be coming up to the area shortly.

I have been on the councils def map and trailwise, but there are so many, and lots with dead ends ?

Hope someone can help
