If Carlsberg made locations to watch the sunset over the River Severn then this would be the best.....probably. It's easy to park and walk (beware peak times can be busy so walking up is an option). The Cotswold Way passes along the edge for stunning views of the Malvern Hills and the Black Mountains. The Sugar Loaf near Abergaveny is easy to pick out on a clear day.
It's an internationally significant grassland home to a breathtaking array of wildflowers, birds and invertebrates and is designated a Site of Special Scientific Interest. It also features a Bronze Age burial mound, 'the Toots'.
