Ogof Hen Ffynhonnau (sometimes known in English as Poacher's Cave) lies in the Alyn Gorge in Flintshire, Wales close to Ogof Hesp Alyn. It was discovered in 1978 after excavation allowed access to Dyer's Adit. Being below a dry river bed, the cave can be prone to flooding in wet weather. There is a short ladder pitch just inside the entrance, and it makes a short trip suitable for novice cavers.
