Trip Notes

  • Mynydd Mawr, a mountain in Snowdonia, North Wales, approximately 7 km west of Snowdon, is known in Welsh as “big mountain”. It overlooks Llyn Cwellyn and is the northern outlier of the Moel Hebog group. From the north, the mountain’s profile is often thought to resemble an elephant lying down, leading to it being referred to colloquially as “Yr Eliffant” or “Elephant Mountain” by non-Welsh speakers.
  • For this trip Andrew M1CJE, Peter M6XPE and I were attempting an overnight camping expedition targeting several mountain summits over a weekend in May.
  • We parked at the Rhyd-Ddu station car park, heading through the forested area to the north, following paths of various descriptions up to the summit of Mynydd Mawr.
  • Each of us completed quick activations on the 2-metre band before heading south across deep heather and boulders, towards Clogwyn y Barcut. From here we navigated our way to our campsite for the evening at Cwmyffynnon. There is a plentiful water supply for camping here but beware of ticks lurking in the undergrowth as sheep graze here.
  • The following morning, we packed away the tents and started towards the nearby summit of Trum y Ddysgl.
