Melfyn Parry walked up Castell y Gwynt (Glyder Fach) on March 5th, 2023 [from/via/route] Started walk from free car park on the Conwy side of Pen y Gwryd Hotel, walked past the hotel & veered off the A498 to take the path which runs alongside the A4086 to Pen Y Pass. From here we crossed the road to join a path running behind the YH, this is also known as the red spot route. The path gradually ascends to the summit of Glyder Fawr , from here we continued on to Glyder Fach & then on to Castell y Gwynt. This was the first time I had been in the area when the wind was gentle enough to allow an ascent of Castell y Gwent.
