Round of Craig Cwm Silyn and Trim y Ddysgl from Cwm Pennant road end. South ridge via Obelisk, small notch and gendarme easily bypassed by path to the east. Views intermittent, cloud more persistent than expected. Down SE ridge to old slate quarries.Topographer5705/08/2019

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 good it looked better to return to Mynydd Tal-y mignedd and follow the ridge down to the deserted quarry.WAYNE ROWLETT01/06/2019

Nuttall Walk 4.2tomd403/05/2018
The Nantlle Ridge from Rhyd-Ddu to near Maen-llwyd. With daughter, Katherine. Followed good path from SH566526 which goes steeply up to the summit of Y Garn. Good visibility here but mist came down for scramble up Mynydd Drws-y-coed. Compass in use for ascent of Trum y Ddysgl and on to Mynydd Tal-y-mignedd. The connecting col between these two hills has a level platform with very steep sides with a somewhat disconcerting dip half way along. It is easy enough to negotiate, though.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

A good day came along at last, and the ridge was just great. Worth the wait.jenx27/06/2016
Very misty & calm on the top, no views at all. The sheep seemed pleased to see us.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
