"Any sort of challenge should be just that..a Challenge. There are many excellent fells on the Dales 30 but even its most ardent admirer would not say Yockenthwaite Moor is one of them. A large expanse of Peat bog of between 2 and 3 km wide marks the boundary of Wharfedale and Wensleydale, the river of peat stretching for many kilometres west of the summit, legend saying that it becomes even worse before it reaches the Pennine Way. I have only come across a worse approach to a summit further north on Mickle Fell, certainly nothing in the Lakes or Scotland can compete.
Trying to be positive I would say that any approach from the north has some excellent access/tracks up to the plateau, Raydale & Semer Water are both very pleasant places to visit and I am led to believe the views are good (my two visits shrouded in cloud despite promising weather forecasts). The other benefit of approaching from the north is that there is an excellent fence which helps what could be a very difficult navigational challenge. The fence leads to the summit and back down to the track back to Raydale. The route from the south is a simple up and down.
I can only add that on my first climb I actually lost a boot in the squelch, I had to dig it out from well over a foot down. Maybe be best when the land is frozen or dry."
