Deel's Hill is a long hill that that sits in the Coquet Valley opposite the Otterburn Ranges. It runs from Chew Green all the way to Blindburn.
This is a really easy bagging as the parking at Blindburn, is right at the foot of Deel's Hill. Simply head west up the slope and within a few kilometres you will have reached the summit.
Look out for a smashing little standing stone on your way up.
Follow the route above or find it on OS Maps. Just over 2km and 180m of climbing.
Once you're done you could head to Chew Green or pop over to Yearning Law and see the ruins of Yearning Hall.
