Llanbrynmair is on a bus route out of Machynlleth. Use it, then basically follow the well signed Owain Glyndwr's Way back in to Mach but detour to tumps if you are a collector. Typical Welsh hill-sheep farming country - the only things you are likely to see all day are Kites, Buzzards and the occasional sheep with her lambs (and her mother's and aunties and cousins and all their lambs).
