From layby on south side of Tanygrisiau. Solo. Through village and up the tarred track to Llyn Stwlan. I quite like taking unusual routes so went up Carreg Blaen-Llyn and then on a narrow path round the east and south sides of Moelwyn Bach before ascending easily to the summit cairn of Moelwyn Bach. Also went to rock 40m NE, which is as high. Continued to Craigysgafn and Moelwyn Mawr.
