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).
Walk from Taly to a wild campsite via Dolwyddelan and through the forest towards Cefn-glas and the lake before heading the the slopes and the duisused quarry where we spent the night.
