The Three Peaks route up Whernside (which fills the centre of the image, if you hadn't noticed) begins just beyond the Ribblehead Viaduct, following the railway for an annoyingly long way before ascending the ridge and doubling-back (grr...) to the summit. From there, it continues left along the ridge then descends abruptly to Bruntscar. Philpin Lane passes to the far side of the large stand of trees, joining the main road at the cluster of buildings in Chapel-le-Dale (village; the whole valley is called Chapel-le-Dale too).
The onward path from the Old Hill Inn to Southerscale Scars is visible from here as a line of slightly darker grass; it then crosses the limestone pavement by the trees and the doline of Braithwaite Wife Hole, then cuts straight across the moor (previously via duckboards, now largely, but not totally, replaced by proper flagstones), off the right of the image to Humphrey Bottom. The final ascent from there to here on the summit is the killer!

The county boundaries are slightly complicated at this, the point where North Yorkshire, Cumbria and Lancashire meet. The nearer valley and most of Kingsdale, beyond the Whernside ridge, are in North Yorkshire, but the head of Kingsdale and the valley beyond Crag Hill/Great Coum at the head of the next ridge, Dentdale, are in Cumbria. However, that next ridge is the Lancashire boundary.
