The BMC has just been informed that the Marine Drive around the Great Orme will be shut for most of Saturday 9 June, until 6 pm. This means that there will be no access to any of the crags above the Marine Drive (i.e all of Upper Pen Trwyn) for most of tomorrow.
The reason for the closure is for the Llandudno stage of a classic car rally.
It may still be possible to access Lower Pen Trwyn by walking across the beach from the pier if tides allow.
