Nuttalls walk 1.4 with Lindsay and Steve. Fine sunny but hazy day. We found this walk tough going, rough underfoot in places - 11.2 miles and 4200ft of ascent - seemed more!Crib Goch23/04/2015

My 9th Summit of the day (although now its a deleted Nuttal is this an anti-summit?).Approached from Pen yr Helgi du and I climbed both sides of the rocky outcrops to officially bag it. Great views as has been said over the valley. This was the penultimate point, now onwards to Pen Lithig Yr Wrach. My route today was Llanfairfechan, the North wales path, branching off to a track, Carnedd Y ddelw, Drum, Foe-Fras, Carnedd Gwenllian, Foel Groch, Yr Elen, Carnedd Llewellyn, Pen Yr Helgi du.Dazingdale05/07/2014
