Keld YH was full when I passed a couple of weeks back (the Muker Show was on), so I stayed at the Tan Hill Inn for a bit of a laugh, just to say I'd done it.
I think a number of hostels on the Pennine Way, although being sold off by the YHA, will remain as hostels or budget accommodation. I stayed at Greenhead YH, which had just been sold at a price below what the YH expected. YH staff were still running it for a while, and the guy at the local pub had bought the building. All the same, the whole YH structure along the Pennine Way is being comprehensively wrecked.
By the way, there was a creepy old fella working his way from one hostel to another, at least, those faced with closure, and would bend anyone's ear for a good hour or five about the closures. He even had copies of letters he'd been blitzing the YH executive with, and would happily read them to you at the drop of a hat!
