The Carneddau (lit. "the cairns"; Carneddau is a Welsh plural form, and is sometimes anglicised to Carnedds) are a group of mountains in Snowdonia, Wales. They include the largest contiguous areas of high ground (over 2,500 or 3,000 feet (910 m) high) in Wales and England, as well as six or seven of the highest peaks in the country—the Fourteen Peaks. The range also encloses a number of lakes such as Llyn Cowlyd and Llyn Eigiau, and the Aber Falls waterfalls. It is delimited by the Irish Sea to the north, the Conwy valley to the east, and by the A5 road from Betws-y-Coed to Bethesda to the south and west. The area covers nearly 200 square kilometres, about 10% of the area of Snowdonia.
Carneddau loop, down via Pen Yr Helgi Ddu. Twisted ankle on final descent; tore a tendon. Took 7 months to recover. Was I leading a group, I'd make sure that if a person twists their ankle, they really are ok to go on. I would also give them the RICE instructions to be sure they don't compound any injury they sustained.
