The Garth has a nice flat top with views across the valleys. Lots of sheep grazing too (March). Also a number of mounds provide some cover from the wind if a break is in order

The earliest evidence of settlement at Ruperra is from between around 700 BC and 100 AD, when an Iron Age Hill Fort was constructed along the ridge of Coed Craig Ruperra. The splendid panoramic views from the top of the ridge would have given the site a strategically strong position. Defensive banks and ditches are still visible around the area of the mound, and continuing work on the site will reveal these more clearly. This hill fort lies within what would have been the tribal territory of a people the Romans called the Silures, who were a fiercely independent nation inhabiting the vale of Glamorgan, Gwent and the valleys

Lovely place to visit you can walk up to the top where there’s a grassy platform. Great views across the forest and out to the sea. Definitely worth a visit

Cefn Eglwysilan is a hill in South Wales, the twin 1,253 feet (382 m) summits of which lie just over one mile (2 km) east of Pontypridd in Rhondda Cynon Taf county borough. Its eastern side lies within the community of Aber Valley in Caerphilly county borough. Like neighbouring Mynydd Eglwysilan, the hill is named after the hamlet of Eglwysilan, the church here being dedicated to an obscure saint Ilan. A wireless transmission station is sited on the more northerly of the two summits (at OS grid ref ST 099911). The southerly one is crowned by a trig point. It is a UK listed Marilyn.
