Waun Garnedd-y-filiast is a top of Carnedd y Filiast on the border of the Snowdonia National park near Cerrigydrudion in North Wales. It is part of the Arenig mountain range. It is also a peak in an area of moorland known as the Migneint.
The summit is marked by a few stones in an area of peat hags on a small plateau of bog. Foel Goch (Arenigs), Carnedd Llechwedd-llyfn and Mwdwl-eithin can be seen.
The top was not included in the Nuttall's original list. However, in 1999 it was surveyed to have the following re-ascent 15.1295 m (49 ft 7.5in). Controversy arose due to it not being quite 50 ft. Some walkers choose only to include it in a Metric list along with 600–608 m sub Hewitt summits. However, most walkers regard it as a full Nuttall by now since it rounds up to 50 ft.[1]
