Riding near Alnwick

We're staying near Alnwick (about 20 mins north up the A1) at the end of July. Obviously, I want to to do some riding, and it would be good to get some rides in with the little one too. 

Any recommendations? 

Kielder is an hour and 45 mins away, and Peebles is nearly two hours so they're both gonna be a bit of a stretch. We're not far from the Cheviots - I guess there must be some good riding there, but it's not an area I know. 

Are there any easier little loops we could do? For reference she rides the Blue at Sherwood. We also like pump tracks and scenic rides. 

Anything else I should be looking at? 

Cheers!
