Circular route, either way round - I'd usually go up the Kitchen path to Llyn y cwn (a few slippy rocks if it's wet but generally easy), then follow the obvious path up to the summit, enjoy the views (potentially some of the best in Snowdonia ......if the current clear skies hold till Wednesday, which is doubtful), then down the NE ridge (a little loose under foot in places but never really exposed).
