Looks nice, looking forward to being able to go back to Snowdonia! I was planning a similar walk earlier this year, going up south of melynllyn, but never got to do it! Was in a cold snap when I tried to get to the llyn Eigiau car park and there was a sheet of ice across an incline on the road about a mile away that I couldn't get up. Had to reverse back to a passing place and turn round and drive back, did a walk from Ogwen instead.
