The Causey Arch car park off the A6076 Sunniside/Stanley approx. 2 miles from Sunniside opposite the Causey Arch public house.
A short walk, approx 2 miles, around the Causey Gorge and crossing the Causey Arch, the world's oldest surviving railway bridge, through deciduous woodland and following part of the Tanfield Railway, with local history information boards detailing the history of the Arch and railway.
From the car park, walk past the toilet building down into the woodland. After a short time, the path forks, take the right fork and go down to the bottom of the gorge alongside the Causey Burn. Ignore the first footbridge and cross the next a few yards further and follow the path through the wood crossing the burn twice more over footbridges. In front of you now is the Causey Arch, the path leads up to and below it before ascending a considerable amount of steps up the right side of the Arch.
Once at the top, turn left and cross the Arch where you can appreciate the full height as you look down. Straight ahead is the railway platform, veer right just before this and walk through a gate which crosses the railway track and up a few steps, which are almost inevitably quite muddy. The path now undulates along as it follows the course of the railway, though initially keeping well above the track. Across to the left is Beamish Open Air Museum which you can just see approx. ¾ mile away.
Follow the path as it drops to run alongside the track and soon crosses it
to lead towards the Causey Burn, cross the bridge over the burn and turn right
(there is another information board a few paces to the left and if the trains
are running, a small café serving refreshments is a further 5 minutes
walk along this way)
After crossing the bridge and turning right, follow the path which gently rises up through the woodland , passes a memorial seat and up a few steps. Turn right and cross the Arch again, this time veer left, signposted for the car-park and follow it back to the car-park.
This walk is enjoyable at any time of year but can become muddy in the Winter or even during wet spells in the Summer, but is at its best in Summer under the dappled shade of the trees.
