This circuit covers a lot of ground, varying from the easy but monotonous travel of the 4WD road into Lake Sumner, to the rough route around the back of Macs Knob. Three Mile Hut is a generously sized hut in an out-of-the-way spot. Its twin is Jollie Brook Hut at the eastern end of Lake Sumner.

Shorten this journey by taking a 4WD vehicle in as far as Loch Katrine, or a mountain bike as far as the Hurunui Swingbridge. A mountain bike will roughly halve the time for this section. Alternately, take it easy and stay at Hurunui Hut on the way, perhaps taking in the Hurunui Hot Springs as well. Given the long slog in from the road end, it's worth taking some time to explore the other tracks in the area.

Access

From Hawarden, follow the signs to Lake Sumner. The long gravel road in follows the Hurunui River before turning off to Lake Taylor. A camping area is located here.

The Track

Lake Taylor to Hurunui Swingbridge

A 4WD track heads around the southern shoreline of Lake Taylor, crosses a low saddle and eases down to Loch Katrine. The shoreline here is decorated with the beautiful yellow kōwhai and white clematis flowers in spring. The rough road continues onward, eventually sidling above the expanse of Lake Sumner itself. 

The track bends up the Hurunui River onto farm flats, where it becomes a lightly poled route. The turn off to Lake Mason is nearby. Easy walking to the swingbridge. The hut is just a little farther.

Hurunui Swingbridge to Three Mile Stream Hut

Over the bridge, head to the bush edge, tall beech forest with an understorey trampled by cows, and turn left. Macmillan Stream is nearby, and a track follows up the true left bank. At a sharp bend, the track runs out. Pick your way upstream from here. There are numerous river crossings, and sections of track on alternate sides of the river. 

After 3km, the route leaves the stream to climb onto an easy saddle. Look out for the distinctive saddle upstream on the true left, and the start of the track, marked with an orange triangle. A quick climb leads up to a boggy saddle with some patches of deep mud. Sidle past a tarn and follow down a small ridge between two streams. The track soon leads out onto river flats and poles to the welcoming little hut, perched on a low terrace.

Three Mile Stream Hut to Hope Kiwi Track

Lake Sumner • By iangeorge. Licence: C.

From the hut, head down Three Mile Stream and ignore the track that leads off into forest: this goes through to Hope Kiwi Lodge. 

A track soon starts in forest on the true right, and becomes a mossy sidle on a tumble of rocks. The track bends around a waterfall above a deep gorge then follows a dry ridge down to a red beech terrace. A signposted junction in the forest marks the junction with the Hope Kiwi Track.

Hope Kiwi Track to Hurunui Swingbridge

Swing right here, and amble easily along the wide track. Lake Sumner is soon visible through the trees, although we just nudge the corner of it before dropping onto flats then back into some dreary forest. There are several quick kilometres back to the swingbridge, followed by the long road journey out to Lake Taylor.
