From Douglas Square Newcastleton follow the track to Blackburn Farm (remember this is a working farm and to be respectful at all times), after which the trail rises steadily across open moorland on a rough track, a finger signpost will guide the way through a gate and follow the fence line across the hillside.
Blackburn Falls are down to your right. It is difficult to approach them more closely, and scrambling down the slope is only advised if you are totally confident of your footing – and of your ability to get back up again! The falls are attractive at any time but are naturally more impressive after heavy rain. Although the falls are at the confluence of Long Gill and Rough Gill, they are known locally as the Blackburn Falls. The path continues down to the site of the former buildings at Annetshiel, probably a summer shieling in former times. However, there is no continuation of this path, and unless you particularly want to see the Annietsheil site, it is best to retrace your steps from the view point above the falls.
If you go down to the Annietshiels site, look for the large “knocking stone” once used to grind corn. Once you regain the stone stell the going is easier and mainly downhill, with good views across Liddesdale and the Black Burn for company most of the way back to the village and the end of the walk.
