Moel Sych (pronounced [ˈmɔil ˈsɨːx]) with a height of 826.7 metres (2,712 ft) is a subsidiary summit of Cadair Berwyn in north east Wales. It is the third highest summit in the Berwyn range after Cadair Berwyn and Cadair Berwyn North Top.The summit lies at the triple historic county boundary point of Montgomeryshire, Denbighshire and Merionethshire. It is the highest point (historic county top) of Montgomeryshire. The summit was often considered to be the highest summit in the Berwyns (and therefore the county top of Denbighshire as well as Montgomeryshire) until the Cadair Berwyn North Top, then known as Cadair Berwyn was found to be of the same height. Later on the OS discovered a new top in between the two, which was 5m higher at 832m. This top, now known as Cadair Berwyn, is listed as Cadair Berwyn New Top on the Nuttall list. The summit has a cairn, and overlooks Llyn Lluncaws in the southern Cwm.

Cyrniau Nod is a mountain summit in north east Wales. It is a former Marilyn, the Marilyn summit now being the nearby Foel Cedig. Its summit has the Snowdonia National Park boundary running through it. A number of rivers and streams rise from near the mountain including Afon Tanat, Afon Cedig and Nant Ystrad-y-Groes. The views from the summit are extensive, if unremarkable due to the featureless, flat moorland surroundings. The summit is marked by a small cairn surrounded by peat bog. Walking on Cyrniau Nod and its tops is made easier by a track that passes close to every top except Cefn Gwyntog. Otherwise, the walking would be tough indeed, requiring tiresome bog crossing for miles.

It is jointly the second highest summit in the Berwyn range along with Moel Sych (though an accurate survey in 2014 does suggest Moel Sych may be slightly lower at 826.7 metres (2,712 ft)). The summit was often considered to be the highest summit in the Berwyns until the OS discovered a new top in between it and Moel Sych, which is 5m higher at 832m. This top, now known as Cadair Berwyn, is listed as Cadair Berwyn New Top on the Nuttall list. The summit is the highest point in the modern Denbighshire council area (possibly jointly with Moel Sych), but not the historic county (which is the higher summit of Cadair Berwyn).
