Melfyn Parry walked up Y Garn (Pumlumon) on June 14th, 2026 [from/via/route] Followed the directions on walk CE100. The route up to Y Garn was hard work, the pathless grass referred to in note 1 also included sections of heather & bilberry which made for slow progress. Once on the summit it was plain sailing to each of the next 4 tops. The return leg was very tricky, the directions were spot on but the terrain was awful, tufty grass, bog & every now & again a faint path, it seemed to go on for ever. [with] Solo walk [weather] Dry & warm day with some faint breezes. - A quiet day in the hills only saw 5 people on Pen Pumlumon Fawr & 2 others on Pen Pumlumon Llygad Bychan. The return section of this walk was very boggy even though we had a long period of dry weather, I imagine this would be dire after any heavy rain. It isn't a range that I would return to, once ticked off the list that's it.
Mark Davidson climbed it on June 3rd, 2010 [from/via/route] Walk ce100 Y Garn (Pumlumon), Pen Pumlumon Fawr (Plynlimon), Pen Pumlumon Llygad-bychan & Pen Pumlumon Arwystli from Nant-y-moch Reservoir [with] Alone [weather] Warm & sunny
Donovan Suddell bagged it 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.
