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

Classic crossing of the Nantlle ridge w Jenx. More than 25 yrs in the offing. Just over 4 hrs, good lines. Finished down in Nebo. Taxi (01286 676767) from the school back to Rhyd-Ddu £15.nordicstar27/06/2016
Not disappointing even after the ridge proper. A good craggy a ascent.jenx27/06/2016
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

Most recent walk on one of our favourite mountain ridges. Staying in Caernarfon made all the 2000-ers easy to plan with no retracing. Buses to Nantlle area are plentiful, and we caught one to Nebo, walked to Llyn Cwmdulyn and followed an incipient path up the NW breast of Mynydd Craig-Goch, recently recognised to be 2001ft. Then took the best going, over Garnedd Goch, to the splendid Marilyn summit. Cloudy, bit of sun, great views. With brother Pete.pwheeler20/09/2013
