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).
MTA sponsored ML 'Contour Master Class' with Paul Poole of Paul Poole Mountaineering. Started from Caffi Moel Siabod. After initial discussions, walked up into the Crimpiau area on and around Craig Wen. Spent the day navigating to specific contour line locations using maps printed only with contour lines and no other features.
