Trip Notes

  • Mynydd Carn-y-cefn is a broad ridge that stretches between the Ebbw Vale and Ebbw Fach valleys in South Wales' Valleys region. It is located in Blaenau Gwent, which was formerly Monmouthshire. This broad-topped ridge runs in a northwest to southeast direction and reaches a height of 550 meters at the trig crowned summit. It is classified as a Marilyn and has a prominence of 176 meters.
  • For my route up this mountain, I found a place to leave the car in the residential area of Blaina. A faint path strikes directly up the steep face of the hill.
  • After gaining the ridge, more distinct paths wind their way across the plateau towards the trig point.
  • While this is relatively small hill, its location makes amateur radio contacts quite painless. I was able to exchange details with operators in Hereford, Holsworthy and Cheltenham.
  • After completing my Summits on the Air activation, I headed back down to the car, with the intent of moving on to activate GW/SW-012 Coity Mountain later in the day.
