The paths were added after local walkers who regularly used them contacted the council. Their registration on the official records of public paths confirms their status as public rights of way and ensures they will be protected for future generations.
Cllr Neil Foster, cabinet member for economic regeneration, said: "Recording paths in County Durham preserves a key part of our often breath-taking natural landscape. By ensuring these paths are protected we hope to encourage more walking and cycling for years to come, creating a healthier, more environmentally friendly county for everyone."
There are now 2,175 miles of public paths in County Durham which can be seen at www.durham.gov.uk/definitivemap.
