Haha! Finally I have found a large, CLEAN public swimming pool in PJ Klang Valley area which is much nearer to my home! This pool is stretched as far as 50m and most importantly it's very well maintained! I went there last night with a rate of RM8 per adult(it's more expensive at night) not including another RM1 for locker service. It offers gyms too for members though.
The Sports Centre is located near to Amcorp Mall or to be specific will be Taman Jaya LRT Station directly same row as A&W. The time schedule and price rate is as below.
