The Callery Gorge walk is an easy 1 hr & 20min walk from the start and you double back again along the same track. The track follows the old sluice pipes laid by the Waiho Sluicing Company in 1912. Callery was the first person to find gold in Franz Josef in 1868. The track quality is very good, from the cul-de-sac in Cowan Street to the Franz Josef water works, it is a gravel service road used almost every day. From there to the site of the Waiho Sluicing Company, again is a good stone surface you can drive your car over. The descent down to Callery Gorge is a very good bush walking track with a hard surface and no water to walk through. Light running shoes will suffice.
