For just a short walk from Alwinton you can bag two hills and a trig point. Green Side is joined onto Lord's Seat so one you have grabbed that then it's just a little saunter over to the other.
At 395m above sea level, Green Side is a canny hill with lovely views toward Copper Snout. And as a bonus, if you are into your Northumberland trig bagging, then on top of Green Side is the Linbrig Trig Point.
If you're bagging Lords Seat first, then it's a simple amble over from there. Otherwise head west along the road from Alwinton for 2km and then north on a clear track all the way to the trig point at the top.
Follow the route above or find it on OS Maps. Just over 3km and 239m of ascent.
