A 13 mile walk using Nuttall's route the one change I would make is the return to Rhyd-Ddu from Craig Cwm Silyn its not the goog and looked better to return to Mynydd Tal-y mignedd and follow the ridge down to the desserted quarry.WAYNE ROWLETT01/06/2019

The Nantlle Ridge from Rhyd-Ddu to near Maen-llwyd. With daughter, Katherine. We came out of the mist as we approached Mynydd Tal-y-mignedd. Craig Cwm Silyn looked impressively steep and we were in mist again as we started up the scramble to the summit. It was not as difficult as it had seemed from afar. From Garnedd-goch we followed the wall NW to get to the road end; horrible boggy bit low down where the route crosses a stream.pwbellarby11/04/2018

As part of West to East traverse of the Nantlle Ridge with 13 year old son. Dropped off at around SH481518. Took us about 9 hours on a very warm but mainly cloudy day.clyoung18/08/2016
Excellent traverse of the whole Nantlle ridge from Y Garn to Mynydd Graig Goch (start at Rhyd-Ddu, end at Nebo). Climbed solo. Weather dry and mild. Drifting mist around summits, but cleared often enough for good views along ridge and to nearby mountains. Only saw 2 people all day (in Lake District would have been hundreds!). Scrambly bit on Mynydd Drws-y-Coed was a highlight but not difficult ... In fact whole ridge was interesting. Lovely views of Lleyn peninsula from the wierd rocky tors on the last summit of Mynydd Graig Goch. Total time 5.5 hours.jamessteel10004/08/2016
Solo. Excellent traverse of the Nantlle Ridge from Rhyd-Ddu, in and out of the mist with numerous Broken Spectres. Less good return to start dropping down to SE and back through Beddgelert Forest.amswanston18/07/2016

Third summit on a S-N traverse. Weather refused to clear with low cloud the order of the day.DanMaisieBex11/06/2016
This was a walk of 2 halves for me. The ridge itself was, on a day like today with such good weather and visibility, is one of the best walks in Wales if not the whole country. The second half, getting back to the start, was not so good. Next time I think I'll walk through to Nebo or Pen-y-Groes and get a taxi back to Rhydd Ddu. Parked the car at Rhydd Ddu and up to Y Garn with incredible views of Anglesey (as far as Holyhead) and Snowdon and later the Llyn peninsula and then a modest scramble up to Mynydd Drws-y-coed and then an easy walk to Trum y Ddysgl and Mynydd Tal-y-mignedd and then a bit more strenuous walk to Craig Cwm Silyn with its strange rectangular stone structures and an easy walk to Garnedd Goch followed by a steepish descent to Mynydd Graig Goch which is worth “going the extra mile” as it has an interesting rocky summit. The whole walk was a really excellent ridge walk. Then came the return home. Tried to get to the public footpath at GR508 482 but there was no eatsharp01/06/2016
