How long do you want? All the roads are good around there, without exception. If you like hills, then head out to the West Allen past the chimneys, from Carrshield head left back over to Allenheads (follow the C2C), turn right, over towards Wearhead. Warmup over, head right, up over Killhope Cross, down to Nenthead, turn left up steep climb (watch for C2C’ers again), down to main road. You can loop round anti clockwise into Garrigill to give another decent climb, or head left at the cross roads, steady climb past Yad Moss ski tows and a long gentle descent down Teesdale to relax. left back over to Weardale when you’re ready, aim for St Johns probably best, hang a left, then a right for a testing climb or two, over to rookhope, turn left for allenheads and a gentle climb, turn right and spin down the valley to the start.
That’s a reasonable introduction to the area and should give you an idea of what is around. If you want a more testing outing then there are plenty of variations to extend the above.
