If it’s the bridleway that starts just off the road about a half mile from Wasdale Head campsite then I’d give it a miss. I’m sure I did years ago. As I rememmber it, the final half up to the summit was push and carry, the first half wasn’t much better. I did it as part of a loop starting at Bowness Knott car park, down to Black Sail YH, up Black Sale pass and down to Wasdale Head. The decent to Wasdale Head is special. The fun ended there. The rest was a slog. I remember being on the summit of the bridleway looking down to Ennerdale water knowing that I was due to start a nightshift two hours later (I was fifteen miles from home). We ended up riding down the fell through ferns and shrubs until we found a path along the river.
Thekettle’s route gets my vote.
