This is a reasonably leisurely route which skirts the southern boundary of the Northumberland National Park giving fine views over the Vale of Whittingham. It is described starting from Alwinton but you could equally well start from Whittingham.
There's a public car park in Alwinton just past the pub. Start here and head S out of the village. Just before the bridge, turn L following the campsite sign. This takes you round the back of what I think is called Clennell Hall and heads E and uphill. The track meets a tarred road and continues E to Biddlestone. Turn L here going E then NE to Alnham and on to Prendwick. You've a climb now to Great Ryle but the views SE over the valley to Thrunton Wood are some compensation. A long run down to cross the River Aln at (038 118) and turn immediately L heading into Whittingham.
Entering Whittingham, turn R at the T junction, then over the bridge and R again for Callaly. There's a junction at Lorbottle (035 066) where you turn R for High Trewhitt and then R for Netherton. Quite a long climb out of Netherton to follow the ridge along and a good downhill section back into Alwinton.
