Have you been to the one that’s free, Muzha Rd Sec 4? I posted information some time ago, here is the link:
It’s well worth a visit.
As for the other one, I need to find the exact address. Do you know where the firestation is at the end of MuXing Road, right near Bao Chiao (Bridge)? It is about 20 meters along from the firestation, same side of the road. It’s now about 180 per swim if you buy a single ticket, with discounts for tickets or term-membership.
