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).
Tanygrisiau via Rhosydd quarry to Moelwyn summit then across to Moelwyn Bach summit and descent via Llyn Stwlan. Scattered showers despite forecast for clear skies.
