From Craig-las along the ridge path to the summit. Lovely day. Descended to the col at about SH669 127, and over a stile with a ROW sign. Descended past a sheep fank and down to the stile at SH6642 1310, and back to the car at Llynau Cregennen.LizH19/04/2024

A walk from Barmouth, across the Mawddach then up Braich Ddu. Followed the rim of the escarpment round for excellent views down onto Llyn Cyri. On starting the climb up the steep ridge, the previously gentle breeze turned into a proper blow, threatening to knock us down (but luckily blowing us away from the steep drop to our left). Stopped off for a visit to the fine Bronze Age cairn, then onwards to the unremarkable summit via the precariously windy outcrops overhanging the void. Carried on down the ridge to the Cambrian Way descent route before Tyrrau Mawr, which is extremely steep but not dangerous. The last section of steep descent is tortuous, a very narrow path through impassable vegetation either side, full of waterlogged bits and obstacles. We were very happy to reach the flat area by Hafotty-fach. Carried on on paths via Llys Bradwen and the intriguing Arthog stones, then back down to Morfa Mawddach to recross the river as the sun was sinking. An excellent 13.75 mile walkthesweetcheat16/09/2022

from Tyrrau Mawr we followed the path that hugs the fence line to the col and up over to the summit which was easy to do so. we came back to the col and you can follow a farm track right that goes to the pony track or as we did take the style down left back to the road. the descent is easy at first but gets steeper but is easy to followAristotle Chip28/12/2019

Great day getting this pair of HuMP's and stack of other stuff walking from Corris hostel to Kings over Cadair.Alex C04/09/2015
Used route C7 in John Gillham's mountains of Snowdonia Guide from Hafotty Fach to get up Tyrau Mawr and then along ridge to Craig-y-Llyn returned over Braich Ddu to the Blue Lake. If using an older map be aware the confier forest has expanded. Footpath past the hut circles gets very boggy, but the tracks for forestry vehicles are a better alternative. Finish with a dip in the sea at Fairbourne.jimclinch05/08/2015
