The country park is situated on the old "Hafod Colliery" site,[2][3] and is 90 acres (0.36 km2) in size, with mainly woodlands and grasslands.

[2] Notable flora is present in the summer, with wildflowers such as the Common Spotted-orchid and Birdsfoot trefoil, whereas in the winter the park is mainly covered in fungi such as the Fly-agaric toadstool.

[3] To reach the depths of the coal seams, 25 million tons of waste stone and shale were extracted and banked onto a spoil tip, forming the hill at Hafod.

[9] In 1991, the Wrexham Maelor Groundwork Trust (now Groundwork North Wales) was established, and in co-operation with Wrexham Maelor Council, they were responsible for landscaping the spoil heap into the Bonc yr Hafod / Hafod Community Woodland following a public consulation into the future of the spoil tip.

[6] A stone-armoured drainage network was also built to prevent water scouring the spoil tip in the event of a flash flood.

[6] Up to 80,000 trees were planted, covering three quarters of the site, with the remaining sections of the park near its pathway network becoming grassland.

One of the two woodlands, covering a proposed 14 hectares (0.14 km2), is set to be planted adjacent to the country park on its eastern side, between it and the A483 dual carriageway, and within the National Trust Cymru's Erddig estate.
