These series of disused quarries, in Llandrindod Wells, are rich in trilobites and graptolites. The largest of the quarries has deep water (also shown on OS maps), and is now fenced over following an accident in which a child sadly drowned. A second quarry, slightly further to the northeast, contains no water and has easy access, with productive shales. Ordovician, Disused Quarry, Rating: ♦♦♦♦
