Coming from the East the best way is to come off the M8 at the A8, then pick up the A89 Bailieston and then Shettleston Road. Then turn down Wellshot Road where the Centre is on the right.
Coming from the West and North my advice is to come off the M8 at the B765, then onto the A89 Shettleston Road.  Then turn down Wellshot Road where the Centre is on the right.
