In reply to it624:
I was up there last week, did a loop from the top car park at Aber, up past Llyn Anafon, up to the col between Drum and Foel Fras. I then dropped down to Aber Falls by a non descript route.
Had planned to go towards Llewellyn, but calf injury meant I cut it short.
Bit of a pain from Aber Falls back to original car park but otherwise a grand day out.....
