If you're aiming to use the long-stay car-park at Nun's Close in Richmond, be warned: Victoria Road (the main through-road to Reeth) is likely to be closed until at least the Bank Holiday Monday (31 August).
If you're heading to Reeth, you should have no problem; there's a good diversion in place. But if you're going to the car-park, set your satnav to take you by way of Quaker Lane (or Quaker's Lane, or Quakers' Lane - even the locals can't agree).
The closure is because there was a bad fire at the filling station on Victoria Road, and it's out of service. So, if you're looking to fill up in Richmond before heading up-dale, use Brooke's filling station on the Darlington Road as you come into Richmond (DL10 7AW).
