This is a nice way to enjoy the 3000ft+ hills situated in the more obscure northern part of the Carneddau range. They are all pleasant rounded summits with a lovely remote setting, and can often be savoured without the crowds associated with more popular areas like Snowdon and the Glyderau. The high starting point in Cwm Eigiau means that it is also a fairly easy walk to accomplish relative to the size of the hills.

SH6887665872 Head southeast of the summit to pick up a path that leads down the broad ridge to just before a large flat shoulder of Gledrffordd. The path now heads right and picks up a small stream that leads down to an abandoned mining complex in Cwm Eigiau.

The name is Llanrwst not Llanwrst.
Before anyone says I’m being pedantic, I’m a native of the town and this happens all the bloody time........
Thanks... sorry!
It can get busy at the start, and if the parking is full, its tricky (you can't!) to find another nearby spot
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.
If you want a day that's a bit longer; instead of heading up into the Cwm, branch off just before Cedryn cottage take the track to the quarry then head up the hillside over Pen Llithrig y Wrach then Pen yr Helgi Du and Craig yr Ysfa before heading to Carnedd Llewellyn
