This is one of my favourite off leash dog parks, it is picturesque and historically interesting: the site of an old coal mine and a major mining accident. You can do a figure 8 route by starting at either end: at the park access on Labieux Road, or the access on Shenton Road. Or park in the Diver Lake Park in the middle and do a short loop in both directions. Signs posted in the park explain where and when the off leash area is in effect.
