- Trum y Ddysgl is the second highest mountain on the celebrated Nantlle Ridge in Snowdonia, North Wales. It is also one of two Marilyns that make up the ridge, the other being Craig Cwm Silyn. The mountain has a dramatic rocky appearance with aretes and glacial cwms. It offers views of nearby Snowdonia mountains Mynydd Mawr, Yr Wyddfa, and Moel Hebog.
- This was our first summit of the second day of a wild-camping weekend in North Wales attempting a number of Summits on the Air mountains.
- Our route started from the glacial cwm to the immediate west of the summit, where we had camped the previous night. We navigated a bearing north-east up a steep boulder field to meet a faint track leading up the ridge to the summit.
- In thick mist we successfully completed our activations from the summit of Trum y Ddysgl, all using the 2-metre amateur radio band.
- Our original plan for the day was to head south towards Moel Hebog, but that changed when Peter from our group injured his knee on the boulder field during the ascent. We took an escape route to the north, picking up a minor road which returned us to the Rhyd-Ddu station car park where we had left the car the day before.
