Donovan Suddell climbed Pen Pumlumon Fawr (Plynlimon) on July 14th, 2021 [from/via/route] Nant-Y-Moch Reservoir using route no ce100 [with] solo [weather] sunny intervals - ce100 route is fine for ascent, but after reaching Pen Pumlumon Arwystli, I recommend returning to Pen Pumlumon Fawr & descending via Llyn Llygad & parallel to Nant y Llyn. The descent on ce100 is far too boggy.
