I had planned to approach through the forestry – visible here – but ended up making the very steep ascent from the Afon Mwyro to the north (right). Good decision, in retrospect.
Approaching from the summit of Pen-y-Bwlch (just under a third of a mile to the east – hence applying its own site for route finding safety’s sake) the cairn here at the bwlch lacks the panoramic views of the summit monument... but structurally is much finer.
