The track starts at the Rarakau carpark, approximately 30 km south of Tuatapere. Tuatapere is 1 hour 15 minutes from Invercargill, 1.5 hours from Te Anau, and 2.5 hours from Queenstown. Return transport to and from Tuatapere can be arranged through the Hump Ridge Trust. Cars are left at Rarakau at the owner's risk.
The South Coast Track from Rarakau carpark along Te Waewae Bay is flat coastal terrain and accessible to all fitness levels. Schools can walk as far as time allows and return the same way. This gives students the coastal Fiordland experience, the Waharoa (gateway) interpretation, and the beginning of the tramline history, without overnight accommodation. The Percy Burn Viaduct cannot be reached as a day return from Rarakau. If the viaduct is the curriculum goal, the full track or helicopter access is required.
Bookings are made exclusively through the Hump Ridge Trust website at humpridgetrack.co.nz. DOC hut passes cannot be used for the track lodges. Multiple packages are available including Freedom, Prime, and Guided options, plus helicopter transport for bags or people on lodge servicing days. Pricing is set by the Trust, not DOC. Confirm current school group pricing directly with the Trust before planning.
The full track requires moderate to high fitness. Each day averages 20 km over 7 to 9 hours, with significant elevation gain on Day 1. The terrain includes formed track, steps, boardwalk, coastal beach, and sub-alpine ridge. The track is best suited to students who have done overnight walks before. Prepare students physically in the weeks before. Day walking on the coastal section has no significant fitness prerequisite.
Full wet weather gear including waterproof jacket, warm layers, hat, gloves, and scarf at all times of year. Fiordland weather changes rapidly. Good boots with grip. Tidal surges and rogue waves affect the coastal sections: check tide tables before departure and do not proceed on the coastal track if waves are washing over it. Carry antihistamine if allergic to wasps. No drones permitted in the national park.
The track begins at the Waharoa, a gateway structure developed with mana whenua Ōraka-Aparima Rūnaka as part of the Great Walk upgrade, carrying one of the largest storytelling interpretation packages DOC has installed on any track. The first section follows the South Coast Track along the coast of Te Waewae Bay through coastal forest. After crossing several streams, the track turns right and begins the climb from coastal forest through mountain beech to the sub-alpine zone. Ōkaka Lodge sits above the treeline in a sheltered amphitheatre. The loop boardwalk from the lodge encircles limestone tors and tarns with 360-degree views of Western Southland. This is the HPE day.
The track follows the Hump Ridge south through forest and exposed sections before descending to meet the South Coast Track and the historic tramline. The descent brings students from the sub-alpine zone into the regenerating native forest that has grown back since the logging stopped in 1929. Edwin Burn Viaduct is the first crossing, now accompanied by a new swing bridge built during the Great Walk upgrade. Then the Sandhill and Percy Burn Viaducts. The Percy Burn Viaduct, 125 metres long and 36 metres above the creek, is a Category One Historic Place registered with Heritage New Zealand Pouhere Taonga. The day ends at Port Craig Lodge, beside the remains of the largest sawmill in New Zealand in the 1920s. An interpretive walk around the sawmill site includes the baker's oven and old wharf piles on the beach. This is the history and environmental education day.
The return follows the South Coast Track along the edge of Te Waewae Bay. Blowholes Beach is only accessible at low tide: watch for tidal surges. The coastal section gives students time to read what they have passed through over three days: the relationship between the logged forest (now regenerating), the viaducts that made the logging possible, the abandoned settlement, and the coast that the timber was shipped from. The Waharoa at Rarakau closes the loop.
From 1916 to 1929, the Marlborough Timber Company removed approximately 14 square kilometres of native forest. The tramline connected the logging areas west of Port Craig to the coast. At its peak the Port Craig sawmill employed over 200 men and produced up to 1,800 cubic metres of timber per month. By 1930 both the supply of and demand for timber had declined sharply and the entire settlement was abandoned. Students walking through the regenerating forest on Day 2 are walking through 90 years of recovery. Railway sleepers from the tramline are still visible near the viaducts. The stumps of felled trees can still be found.
The viaducts were built from Australian hardwood specifically selected for its durability under load. The Percy Burn Viaduct is 125 metres long and 36 metres high, supported by trestle bents of hardwood timber. It was fully repaired in 1994 by the Port Craig Viaduct Charitable Trust, funded through community effort, after decades of neglect following the closure of the tramline. The other viaducts were repaired in 1999. The viaducts are the physical reason the tramline was possible at all: without them, the logs could not have been moved from the steep-sided creek valleys to the coast.
The South Coast Track carries three distinct layers. The first is the Maori seasonal use of this coast for fishing, eeling, and hunting, with camps along the Waiau River near Tuatapere and tracks very close to today's route. The second is the 1896 government cut of the coastal track to provide access to the Cromarty and Te Oneroa gold mining settlements when shipping was unreliable. The third is the 1908 telegraph line installation along the same route, linking the Puysegur Point Lighthouse with Orepuki. Insulators, wire, and remnant hut foundations can still be found. Three layers, one track.
Ōraka-Aparima Rūnaka are the mana whenua of this area. They were partners in the Great Walk upgrade project alongside DOC, the Hump Ridge Track Charitable Trust, Rowallan Alton Inc, SILNA landowners, and the Southland District Council. The Waharoa (gateway) at the Rarakau track entrance was developed with Ōraka-Aparima Rūnaka and carries interpretation of the Maori relationship with this landscape. The interpretive storytelling installations throughout the track include the stories of mana whenua alongside the logging and tramline history. Teachers exploring this thread in depth should consult Ngāi Tahu teacher resources at ngaitahu.iwi.nz.
The Hump Ridge Track sits within Te Wāhipounamu, the UNESCO Southwest New Zealand World Heritage Area. It was conceived, funded, built, and run for 20 years by the people of Tuatapere, a town of around 600. The Great Walk upgrade was announced in 2019 and the track opened as New Zealand's 11th Great Walk on 25 October 2024. The community's role in creating a national and international asset from a logging landscape is itself a curriculum thread in geography and local history.
These prompts build on what students experienced on the track: the physical weight of crossing the Percy Burn Viaduct, the railway sleepers still in the ground, the regenerating forest, the abandoned sawmill, and the coastal track's layered history. DOC, Heritage New Zealand Pouhere Taonga, and Ngāi Tahu sources are the check sources. Gen AI is the thinking partner tested against what students observed.
The Percy Burn Viaduct is 125 metres long and 36 metres high. Ask a gen AI chatbot how wooden viaducts like this one were built before modern equipment. Then think about what you saw on the track: the sleepers in the ground, the timber trestles, the size of the valley below. Could you have built it? What would have been the hardest part?
Ask a gen AI chatbot what happens to a forest after logging stops. Then describe what you saw on Day 2 of the track: was there new growth? What kinds of trees? How long do you think it had been growing back? Does the AI's answer match what you saw?
Ask a gen AI chatbot why a large sawmill might close after only 13 years of operation. Then check what the DOC track information says about why Port Craig was abandoned. Did the AI give the same reasons? Were there any it missed?
The Port Craig schoolhouse is now a trampers hut. Ask a gen AI chatbot what life might have been like for children living at a remote sawmill settlement in 1920s New Zealand. What would school have been like? How does that compare with your school?
Ask a gen AI chatbot to explain what structural forces a wooden trestle viaduct like Percy Burn must resist, and how the design of trestle bents addresses those forces. Then evaluate the account against what you observed on the viaduct: the dimensions, the materials, the deck and handrail structure. Is the AI's engineering account consistent with the structure you walked across?
Ask a gen AI chatbot to describe the ecological succession process in native New Zealand forest after logging. What species establish first? What conditions are required for the original forest composition to return? Then connect the account to what you observed on Day 2: what stage of succession does the regenerating forest appear to be at, and what does that tell you about the timeline?
In 1916 the Marlborough Timber Company built a tramline to harvest native forest. The logging was legal and met demand at the time. Ask a gen AI chatbot to explain how New Zealand's approach to native timber logging changed over the 20th century and what led to the 1980s ban. Evaluate the response against DOC sources and any historical records you can find. Does the AI reflect the actual policy history accurately?
The Hump Ridge Track was built by the community of Tuatapere and run privately for 20 years before becoming a Great Walk in 2024. Ask a gen AI chatbot to explain what Great Walk status means for a track: what changes in management, investment, pricing, and access. Then check the DOC and Hump Ridge Trust websites. Does the AI's account reflect how the Trust-DOC partnership actually works for this specific track?
The Percy Burn Viaduct is a Category One Historic Place registered with Heritage New Zealand Pouhere Taonga. Ask a gen AI chatbot to explain what Category One designation means in New Zealand law, what protections it provides, and what obligations it places on owners or managers. Evaluate the response against the Heritage New Zealand website and any documentation you can find about the viaduct's management. Where does the AI's account reflect the actual legal framework? Where does it generalise?
The logging at Port Craig was part of a broader history of native timber extraction across New Zealand. Ask a gen AI chatbot to trace the policy history from the early 20th century through to the native timber logging ban in the 1980s, including the drivers of change and the role of conservation advocacy. Evaluate the account against DOC historical sources and any peer-reviewed environmental history you can locate. Does the AI convey the complexity of how policy actually changed?
Ōraka-Aparima Rūnaka were partners in the Great Walk upgrade project and in developing the interpretive storytelling installed throughout the track. Ask a gen AI chatbot to describe what it means in practice for an iwi to be a partner in a DOC infrastructure project of this kind, and how that relationship differs from consultation. Evaluate the response against Ngāi Tahu sources and any documentation you can find about the Ōraka-Aparima Rūnaka role in the Hump Ridge upgrade.
The forest logged by the Marlborough Timber Company has been recovering for approximately 90 years. Ask a gen AI chatbot to evaluate how far an indigenous New Zealand forest can recover in 90 years and what the limiting factors are: seed dispersal, soil conditions, canopy competition, and introduced predator pressure. Evaluate the account against peer-reviewed ecological literature. Does the AI's account of forest succession reflect what current ecology tells us about native forest recovery timelines in Fiordland?
| Level | Years 5–6 | Years 7–10 | Years 11–13 |
|---|---|---|---|
| 1 | Student names at least one thing encountered on the track and connects it to the logging history: a viaduct, a railway sleeper, the Port Craig schoolhouse, or the regenerating forest. Understands the landscape was changed by industry and is now recovering. | Student identifies the Percy Burn Viaduct by name, states its Heritage New Zealand Category One status, and explains its role in the Marlborough Timber Company's tramline operation. Places the logging era (1916 to 1929) in the context of broader New Zealand native timber policy. | Student identifies the viaduct, its heritage designation, and the ecological and policy context of the logging era. Locates the relevant Heritage New Zealand, DOC, and ecological sources that describe the site and its recovery trajectory. |
| 2 | Student makes one explanatory connection: why the viaduct was needed, what caused the sawmill to close, or what the regenerating forest tells us about the timeline of recovery. The connection links something observed to a reason. | Student explains one mechanism in depth: the structural engineering of a wooden trestle viaduct, the ecological succession process in a recovering native forest, or the policy sequence that led from legal logging to the 1980s ban. Links the mechanism to something observed on the track. | Student constructs a causal account: the relationship between the tramline engineering and the scale of forest extraction, the interaction between Heritage New Zealand designation and practical conservation management, or the ecological limiting factors on forest recovery in this specific landscape. |
| 3 | Student compares what a gen AI chatbot said about wooden viaduct construction, forest recovery, or the sawmill closure with what the DOC track information or Heritage New Zealand says. Can say where the AI was accurate and where it was not. | Student documents a systematic comparison between a gen AI chatbot's account of one technical or historical aspect of the track and a primary source. Identifies at least one discrepancy and explains what it reveals about the AI's limitations with specific place-based historical or ecological knowledge. | Student evaluates a gen AI chatbot's account of Heritage New Zealand designation, native forest policy history, or Ōraka-Aparima Rūnaka co-governance against primary and peer-reviewed sources. Documents the comparison and draws conclusions about where AI is reliable and where it falls short for this domain. |
| 4 | Student explains what being on the track added that a photograph, documentary, or classroom description could not: the physical sensation of crossing the viaduct, the height of the valley below, the smell and sound of the regenerating forest, the scale of the coastal walk. Names at least one thing that cannot be replicated on a screen. | Student articulates what walking the tramline route through regenerating forest provided that secondary sources cannot: the spatial relationship between the viaduct, the valley, the logging debris underfoot, and the recovering canopy above. The physical experience of distance across three days. | Student reflects on the epistemological difference between three days of physical encounter with a landscape shaped by industry and now recovering, documentary historical and ecological sources, and gen AI-generated explanation: what each can and cannot constitute as evidence in an Environmental Education or History context. |
| 5 | Student generates one question about the track, the viaduct, the logging history, or the regenerating forest they want to investigate further. Identifies one action connected to what they learned: finding out about Heritage New Zealand, researching the Marlborough Timber Company, or learning more about native forest recovery. | Student formulates a testable inquiry question about one aspect of the Hump Ridge Track: the engineering of the viaduct, the rate of native forest recovery, or the community governance model. Proposes a method and identifies at least two high-quality sources beyond what the track provided. | Student designs a structured research question about the track's heritage, ecology, or governance. Identifies three sources across primary, peer-reviewed, and institutional categories. Articulates how the inquiry connects to a current policy debate, a conservation question, or an action the student can take. |
