Melfyn Parry hiked Trum y Ddysgl on March 20th, 2019 [from/via/route] Start & finish in lay-by at Rhyd Ddu 566526. Very steep incline to summit of Y Garn, low cloud until above 600m & then came out into sunshine. Great views over to Snowdon to the east & Nantlle & Anglesey to west & north west. Continued on ridge to scramble up Mynydd Drws y Coed, quite challenging in one or two sections. Walking in low cloud again, very wet, with limited visibility. Continued along Trym y Ddysgl & on up to the obelisk on Mynydd Tal y Mignedd. Had lunch in the shelter of a dry stone wall. Descent from here was quite a steep grassy bank crossing over streams & disused inclines. At 540502 the path was not evident & we through bogland & forest to find the forest track at 544498. From there easy route back to start. [with] ChW & CW [weather] Mostly cloudy, short spell of sunshine on Y Garn

Chris Newham walked up Trum y Ddysgl on February 18th, 2017 [from/via/route] gw201 [with] Craig [weather] Low cloud - Very steep decent at end the ladder style has gone & a new barbed wire fence installed as a result we had to go all the way down the very steep slope & climb a padlocked gate to get back on track then you have to walk across very boggy ground on a footpath not often used. However despite this a very good walk.
