Hello Avril. My mother and father also talked about the fun they had swimming in the pool above Pontllotyn[especially when they were courting].Unfortunately I dont recall the name of the pool but I believe it was on the mountain road between Pontllotyn and Fochriw. My grandmother lived in Pontlottyn most of her life and lived for the best part of it in New Road which in those days was the last house before the pond which must have been about 1/2 mile away
