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.
Start at GR685602 and walk up road to Llyn Lugwy. Continue up to the col and then turn left towards the summit of Carnedd Llywelyn (1064m). Head towards Carnedd Dafydd but due to increasing ice we descended down at GR683638 back towards the lake. Skirt around the north edge of the lake and pick up the path and return down back to car park.
