Foel-fras (944 m) is a mountain in the Carneddau range, about 10 km east of Bethesda in North Wales. It lies on the border between the counties of Gwynedd and Conwy. With a height rising to 944m it is officially the eleventh highest summit in Wales. Foel-fras is located at the northern end of the main ridge of the Carneddau, between Drum to the north and Foel Grach to the south, with the subsidiary summit of Garnedd Uchaf (926 m) between it and Foel Grach. Due south and 400 m below lies the reservoir of Llyn Dulyn, while the smaller reservoir of Llyn Anafon lies to the north.

Llyn Cowlyd is the deepest lake in northern Wales. It lies in the Snowdonia National Park at the upper end of Cwm Cowlyd on the south-eastern edge of the Carneddau range of mountains, at a height of 1,164 feet (355 m) above sea level. The lake is long and narrow, measuring nearly 2 miles (3 km) long and about a third of a mile wide, and covers an area of 269 acres (1.1 km2). It has a mean depth of 109 feet (33 m) and at its deepest has given soundings of 229 feet (70 m), this being some 45 ft (14 m) greater than its natural depth, the water surface having been raised twice by the building of dams.
Llyn Geirionydd lies in a valley in North Wales where the northern edge of the Gwydyr Forest meets the lower slopes of the Carneddau mountains. The lake is almost a mile long and covers an area of 45 acres (180,000 m2), but is never any deeper than 50 ft (15 m) according to Jehu’s survey. The lake can be reached by car from Trefriw or Llanrwst in the Conwy valley, the lane passing through the hamlet of Llanrhychwyn, or from the road through the Gwydir Forest. Access is not particularly easy by either route, but this has not stopped the lake being the only one designated in Snowdonia to permit power boats and water skiing. Many visitors also walk to the lake from the village of Trefriw or from the neighbouring lake of Llyn Crafnant, which runs parallel to it, but a mile distant, the two being separated by Mynydd Deulyn, “mountain of the two lakes”.

Llyn Eigiau is a lake on the edge of the Carneddau range of mountains in Snowdonia, Conwy, Wales. The name Eigiau is thought to refer to the shoals of fish which once lived here. Early maps refer to it as Llynyga. It is thought that a small number of Arctic char exist in the lake after they were transferred here from Llyn Peris, and certainly it is one of the few lakes in Wales to have its own natural brown trout.

The summit has two large shelter cairns, hollowed out from a large Bronze Age burial cairn.
