Christina Lander walked up Diffwys on June 1st, 2023 [from/via/route] Y Llethr - Crib-y-rhiw - Diffwys, from the west [with] Dick [weather] Hot & sunny
Melfyn Parry climbed Diffwys on May 17th, 2023 [from/via/route] Started walk from the car park at Maes y Garnedd at 08:45 & followed the route as described on GW159. Notes were generally very good. Path was not easy to follow down from Rhinog Fawr but eventually reached Bwlch Drws Ardudwy & struggled again to find the start of the path up Rhinog Fach, once found it was easy to follow to the summit although it was a hard slog. Once at the top navigation was straightforward to Llyn Hywel albeit quite slow progress due to the nature of the path. Another slog up to Llethr but easy path to follow. From Llethr the grassy path was much easier to make quicker progress & the next three tops (Crib y Rhiw, Diffwys & Diffwys West Top) were reached without difficulty. I decided to go down to Port Scethin & take the bridle path back but this was a mistake as the bridle path as shown on the OS didn't exist. It was hard going through reed beds, boggy land & clumps of heather & bilberry bushes to get back to the path leading back to the carpark, only seeing the bridle path for the final 400m or so. [with] On my own [weather] Sunny spells & quite warm at times especially on uphill sections when in lea of the breeze. On the tops the breeze was chilly. - Stunning views in all directions. Well worth the effort but the ascents are quite hard work, not for the faint hearted.
