Ogof Dydd Byraf is a cave which extends under Esclusham Mountain in north-east Wales from its entrance in the south face of the Minera Limeworks quarry. It was originally discovered and explored in 1964 by the Wrexham Caving Club, before they were merged into the North Wales Caving Club. [2]
After a short series of mined passages there is a narrow 10 metre pitch into the main levels consisting of a series of well-decorated galleries. Some of the passages come very close to the cave Ogof Llyn Du whose access is blocked by a deep and difficult sump.
Over the years this cave had been under threat by the quarry operations, [3] but it is now protected as an SSSI. [4] and owned by North Wales Wildlife Trust [5]
Clwyd is a preserved county of Wales, situated in the north-east corner of the country; it is named after the River Clwyd, which runs through the area. To the north lies the Irish Sea, with the English ceremonial counties of Cheshire to the east and Shropshire to the south-east. Powys and Gwynedd lie to the south and west respectively. Clwyd also shares a maritime boundary with Merseyside along the River Dee. Between 1974 and 1996, a slightly different area had a county council, with local government functions shared with six district councils. In 1996, Clwyd was abolished, and the new principal areas of Conwy County Borough, Denbighshire, Flintshire and Wrexham County Borough were created; under this reorganisation, "Clwyd" became a preserved county, with the name being retained for certain ceremonial functions.

Ogof Hesp Alyn was discovered by North Wales Caving Club in 1973 in the Alyn Gorge near Cilcain, Flintshire, Wales. Reaching the end of the cave is a serious commitment involving 24 pitches and the draining of two sumps. The proliferation of short, awkward and muddy pitches appear best suited to be tackled by wire ladders, but in the 1980s a team of divers from the Wessex Caving Club who passed the sumps, concluded that single rope technique was preferable, avoiding the need for excessive numbers of people to carry the equipment. A perpetual siphon has since been used at the first sump which does a good job of keeping the water level relatively low, when working properly.
Ogof Hen Ffynhonnau 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.

The Clwydian Range and Dee Valley is a designated Area of Outstanding Natural Beauty (AONB) and proposed national park, located in north-east Wales, covering the Clwydian Range, and the valley of the River Dee. Designated in 1985 as the Clwydian Range AONB, and expanded to its current form in 2011, the Area of Outstanding Natural Beauty includes: medieval field systems, open heather moorland, prehistoric hillforts, limestone crags, broad leaved woodland, wooded valleys, and farmland. In 2018, an estimated 1.1 million people visited six key sites across the AONB, generating approximately £24.1 million to the Welsh economy, according to Natural Resources Wales. The AONB falls within the jurisdiction of the local authorities of Denbighshire, Flintshire, and Wrexham County Borough, with the majority, 80% of the AONB in Denbighshire, and the remaining 20% split evenly between the other two authorities. The AONB is the largest of only five AONBs in Wales, and one of the 46 in the United Kingdom. Additionally, it is one of only 8 protected areas of Wales. Long-distance footpaths; Offa's Dyke Path, and the Clwydian Way pass through the AONB. The area of the Clwydian Range and Dee Valley AONB is 390 km2 (150 sq mi), and has been proposed by the Welsh Government to become Wales' fourth national park.
