1.1 mile / approx 760 ft ascent
As seen as though Steel Knotts has two churches at its base I've chosen to offer a route from each of them. This one begins at the old church where you'll find roadside parking for about 10 sensibly parked cars.
The route is easy enough to pick up from behind the church, but make sure you don't follow the path alongside the wall otherwise you'll end up hacking your way through chest high bracken to get back up to the correct path. You need to take the path which leads up to the right hand side of the large enclosure and then diagonally up the fellside.
If you're feeling energetic, you can cut the corner at the summit ridge and instead of going through the gate, walk up the side of the wall.
