Final day of three in Wales with Smithy & Shaky: windy & with rain forecast. From Idwal Cottage round Llyn Idwal & up the NE ridge of Y Garn with a quick detour to that summit. Over to Foel-goch while the other two took the lower traversing path, then round to a mist shrouded Elidir Fawr. Got greedy & headed up Mynydd Perfedd at which point the promised rain arrived big time, not the ideal point for Shaky to discover that he had forgotten his overtrousers! Over to Carnedd y Filiast & then back to the first stile underneath Mynydd Perfedd & followed faint path on vague ridge between Cwm Perfedd & Cwm Bual. Dropped into the latter to reach the minor road & a wander back to the start.NotReallyABagger23/04/2018
