Mynydd Allt-y-grug is a 338-metre-high hill immediately west of Ystalyfera in the county borough of Neath Port Talbot in South Wales. Its twin summits are around 400m apart. The upper part of the hill is largely covered in heather whilst conifers clothe its western slopes and gorse, bracken and bramble cover much of its rough landslipped eastern side which rises above the Swansea Valley, drainage on this side flowing to the River Tawe. == Geology == The hill is formed from multiple layers of Pennant Sandstone with intervening mudstone layers and occasional coal seams. All are tilted to the south and southwest towards the axis of the South Wales Coalfield syncline. The lower parts of its western slopes are mantled by glacial till. Much of the eastern side of the hill is a large landslip which is intermittently active and destructive of properties in Ystalyfera and Pantyffynnon.〔British Geological Survey 1:50,000 map sheet 230 ''Ammanford'' & accompanying memoir〕
