I would say a grade 1 or maybe 2 scramble from the north west side. Very loose so big danger of rocks falling on anybody behind you. Harder coming down.andrew brown11/11/2017
From SE, S ridge fairly straightforward scramble, care with loose rock hence we stayed close together. Compact summit with fallen rock flake at hp, SH 59472 59857. Rainy breezy early Sun morning, with Rick, and Maria still in her RHBSoc party shoes! Technically out of bounds since 2016 rockfall.RHW11/06/2017
A second ascent w Rob and Maria. Up the chossy North ridge in the wet, just watch out for all the loose rock and hope none falls on you. Interestingnordicstar11/06/2017
Climbed the right side of the south face via the only apparently non precipitous route. Moderate exposure towards the top but the scrambling thankfully is not too demanding. Used a well secured iron chain in the lower section and felt glad I'd brought slings with me for the upper third, though I used these more for confidence and not for technicality of what was required. A lot of the rock is loose and dubious so take extra care with what you're clinging on to. There could be another way up the western side though this is more visible from the power station below and involves negotiating an uninviting boulder slope. There is evidence of very recent landscaping work going on in the immediate area so this could potentially make the top off limits weektime for the short term. If possible, I would recommend the high level return to Llanberis, through the quarries and down to the road at SH 587600. A quite remarkable walk.Alex C03/06/2017
