The Moelwynion (a Welsh plural, sometimes anglicised to Moelwyns) are a group of mountains in central Snowdonia. They extend from the north-east of Porthmadog to Moel Siabod, the highest of the group. The name derives from the names of the two largest mountains in the group, Moelwyn Mawr (great white hill) and Moelwyn Bach (little white hill).
Leading the old man, we took the classic route up Siabod, before West and then South through boggy ground. Dropped down in to Nant Gwynant and up to Pen-y-Pass. FInally an ascent up the "red dot path" shoulder to Glwynder Fawr, to Y garn and down the Y Garn Eastern descent.
