The track can be travelled in either direction but the route from Golden Bay to Karamea is described here.
Brown Hut to Perry Saddle Hut Brown Hut is located only five minutes walk from the carpark at the end of Aorere Valley road. There is a campsite located close to the hut. The track from Brown Hut crosses Brown River and a grassy flat before climbing through regenerating forest. The route to Perry Saddle is almost entirely uphill, and has a consistent gradient. The zigzag path follows the route of a bridle track surveyed and built in 1886 by John Saxon. The track climbs steadily through mature beech forest, mostly red beech (
Nothofagus fusca) and hard beech (
Nothofagus truncata) trees, but there are also podocarps including
rimu and
miro,
southern rātā and other species such as
kāmahi. Birds that may be seen in the forest on the climb to Perry Saddle Hut include
tomtits,
robins and
bellbird.
Kākā may also be seen or heard near the top. There is a side branch of the track reached after about 90 minutes climbing. This leads down to Shakespeare Flat on the Aorere River. After 3–4 hours climb, the Aorere shelter and campsite at about elevation provides a place to rest. The highest point on the Heaphy Track, at , is reached after another hour. There is a lookout point nearby. From here, it is another 30 minutes walk to Perry Saddle Hut. The hut has 28 bunks.
Perry Saddle Hut to Gouland Downs Hut From the Perry Saddle Hut, the track passes over the saddle and follows the true left of the Perry Creek. There is a side-trip route up to the peak of Mount Perry, at elevation that in suitable conditions provides panoramic views over the Aorere Valley and Golden Bay towards the North Island, and inland over the Gouland Downs and the rest of the Kahurangi National Park. The main track re-enters forest for about an hour until reaching the edge of the Gouland Downs. The route then descends gradually to the Cave Brook and then reaches the historic Gouland Downs Hut. The existing hut was built by the Collingwood County Council in 1936.
Geology of the Gouland Downs This area is a
peneplain, a low-relief plain formed from prolonged erosion. Beneath the tussock in the Gouland Downs are sandstone and mudstone
sedimentary rocks that were formed in the
Lower Palaeozoic era around 400 to 500 million years ago. They are some of the oldest rocks in New Zealand. These rocks were worn down by erosion to form the peneplain around 100 million years ago. They were then submerged beneath a shallow sea, and limestone was deposited on top of the older sedimentary rocks. The land was subsequently uplifted, and erosion removed most of the limestone, leaving isolated outcrops that now appear like tree-covered islands in the tussock landscape. The remaining areas of the Gouland Downs have shallow and infertile soil where the only plants that thrive are tussocks and rushes. This release is part of a programme to ensure the survival of the species. The Gouland Downs area was chosen for the release partly because the Kahurangi National Park has had intensive pest control over many years, and along with natural barriers, this has kept down the population of predators such as cats and ferrets. Takahē can now be regularly seen near Gouland Downs Hut. The hut is named after John Saxon who surveyed the track in 1886. The endangered
blue duck (or whio) may be seen in this section of the route.
Saxon Hut to James Mackay Hut The route descends gently through forest to the Saxon River, and then over a flat to Blue Duck Creek. It then climbs through forest in a long sidle around the slopes of Mt Teddy before reaching the Mackay Downs. The James Mackay Hut is on the edge of the downs, and is situated on a terrace above the track. It has views of the
Heaphy River mouth and the
Tasman Sea to the south-west.
James Mackay Hut to Heaphy Hut The track descends through forest along a spur between Deception Creek to the south and the Lewis River to the north. The type of vegetation changes markedly as the track descends towards the Heaphy River. Stunted manuka and beech trees seen at the top become taller, and the sub-canopy and ground vegetation becomes more dense. At the bottom of the descent, there is typical West Coast rainforest, and the first
nīkau palms can be seen. There is a shelter near the junction of the Lewis and Heaphy Rivers. The route then crosses the Heaphy River and the track then follows a large bend in the river under limestone bluffs. The track follows the true left of the Heaphy River and crosses the Gunner River near its junction with the Heaphy. The vegetation along this part of the route is lowland podcarp forest, with an increasing number of nīkau palms closer to Heaphy Hut, where they dominate the forest. The Heaphy Hut and campsite is around back from the beach, overlooking the Heaphy River mouth, with a view of surf and the Tasman Sea.
Heaphy Hut to Kōhaihai River mouth This final section of the track is all close to the coastline, with the route partly in forest and partly on the beach or beach margins. There are several stream crossings along the route. The Katipo Creek shelter is located at the mid-point of this section of the track. The landscape of the coastline with its pounding surf and the coastal forest with groves of nīkau palms is described by some as the highlight of the track. Towards the end of this section of the track there is a climb from
Scotts Beach to around over a saddle set back from Kōhaihai Bluff. The track then descends to a crossing of the Kōhaihai River and the end of the track at the car park. ==Mountain biking==
