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).
A trip going over navigation with three trainee mountain leaders leaving from the car park near Gelli lago moving up to Bwlch y Battel and then up Cnicht descending north east towards Llyn yr Adar looking for various lumps and bumps then up to the llyn at the source of Afon Cwn-y-foel and then back to Llyn yr Adar and then down via the steep track down into Cwm Llagi and then back down to the road poor visibility most of the day.
