Ogof Nadolig, Cave system in Alyn Gorge, Wales
The cave extends 300 meters underground through limestone formations, featuring narrow passages that require crawling and careful navigation through multiple chambers.
The North Wales Caving Club made a significant discovery of this underground system in 1978, marking a new chapter in Welsh speleological exploration.
The Welsh name Ogof Nadolig translates to Christmas Cave, reflecting the traditional practice of naming geological formations in the native Celtic language.
Access to the cave requires following a track east on the north side of the valley toward a sewerage treatment plant, then walking uphill.
The final section of the cave connects to the surface through a shaft sealed by a locked manhole cover, creating an unusual exit point.
