A hiking area reached from the Upper Mangatawhiri Campsite at Mangatawhiri in Franklin, Rata Ridge carries a 3.5 Google rating. As the name suggests, the walk sets out from the campsite itself.
Ridge tracks like this one reward a bit of preparation. Southern Auckland's forested ranges hold some of the region's last kauri, so walkers are asked to scrub their boots at cleaning stations and check for closures before setting out, as kauri dieback rules can close tracks at short notice. Expect a steady climb, mud after rain and patchy phone coverage once under the canopy; regulars carry plenty of water, tell someone their route and time the walk to be down before dark.
That mix of farmland edge and native bush makes this a solid day out for anyone living in or visiting Franklin's quiet southern corner.
