If you like waterfalls, you will like today. After a yummy breakfast beside the bubbling brook, you cross the bridge over the creek and start walking through the open plain then back into a mossy rainforest. 2.6km after leaving Kia Ora (about 1hr) the track leads you out of the forest and into a large clearing and historic Du Cane Hut. (There is a very rustic open air pit toilet just before the hut.)
The hut and area is worth dropping packs and having a look around. The hut is for day use only, no camping (except in an emergency).
Follow the signposted Overland Track (veering left just past Du Cane Hut) for another 1.7km to come to the first side trip to waterfalls. This first side track leads down to Dalton & Fergusson Falls, it is about a 1km return trip (steep in places) to the two waterfalls. Back on the Overland Track it is just over another 1km to the side trip to Hartnett Falls. Hartnett Falls are the tallest of these three waterfalls; it is a 1.5km return sidetrip to the view at the top of the falls. These side tracks are slippery and have large unfenced cliffs.
This is about halfway through the day’s walking. Continue along the Overland Track for another 4km as it leads through the forest, up and over Du Cane Gap then down to Windy Ridge. As you approach the Bert Nichols Hut, the forest starts to dry out, becoming mostly eucalypt and you will see the Du Cane Range come into clear view, towering above (to the right).
Try not to get sucked into the vortex of Bert Nichols Hut, there are some great outdoor areas beside and behind the hut where you can soak up majestic views of the wide valley below Du Cane Range.
