From the Wikipedia article
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 landslide eastern side which rises above the Swansea Valley, drainage on this side flowing to the River Tawe.

Background
Visiting
The upper parts of Mynydd Allt-y-grug are designated as open access under the Countryside and Rights of Way Act 2000 as is the conifer plantation which extends across much of its lower western slopes. There are no recorded public rights of way to its summit but a public footpath skirts the hill through the forest to its west and northwest and connects to Ystalyfera via the farmstead of Penlan-fach. There are however a number of other tracks which run across its slopes.
