This has been listed as you can purchase a ticket and overnight stay but you do not have to use the ticket.
Motorhome pitch
Park your motorhome on the hard standing at Stump Cross, with fabulous hilltop views across the Yorkshire Dales National Park. The café is open during the day for breakfast and lunch but you must have your own power, toilet and washing facilities to pitch overnight. Maximum stay 1 night.
There is only a nominal overnight charge of £5 for the pitch, so we ask that you book a cave entry ticket and/or table reservation as part of your stay, which you can add to your pitch booking.
