A short drive from Layside is the market town of Haltwhistle, claiming to be at the geographical centre of Britain. The South Tyne Trail can be accessed from behind the railway station at Haltwhistle, and follows the South Tyne River to Lambley Viaduct and beyond. There are some lovely views of the river as well as Hadrian’s Wall Country, and plenty of opportunities for your four-legged friends to cool off in the water. Salmon can also be seen jumping upstream in Autumn as they migrate to their breeding grounds. This part of the trail is roughly 4.5 miles one way to the viaduct, and requires some sturdy footwear in parts! Comprising of a series of elegant stone arches, Lambley Viaduct is approximately 850ft long and once carried the Haltwhistle to Alston railway which opened in 1852 to haul coal from the Alston mines, and was closed in 1976. It is a particularly elegant example of Victorian engineering: the river is crossed by nine 56 ft wide arches 105 ft above the river. This is a favourite walk of ours and loved by Archie – stopping at the viaduct for a cup of tea and a sausage roll before turning back.
