Caerphilly mountain lies between Cardiff and Caerphilly at the southern edge of the South Wales coal field. It is 271 metres in height.
Since 1957 there has been a small wooden Snack Bar located near to the summit. In September 2011 this is being replaced by an eco-friendly permanent building, with under floor heating, solar panels and rainwater-flushed toilets, at a cost of £300,000.[1]
