About the Forgotten World Highway
The Forgotten World Highway follows ancient Māori trade routes and later pioneering tracks through remote farmland, native bush, and dramatic gorges. It passes the self-declared Republic of Whangamōmona, established in 1989, and offers views of Taranaki Maunga and central North Island volcanoes from the saddles.
Cyclists encounter constant elevation changes and must manage mixed sealed and unsealed surfaces. The Tangarakau Gorge section provides particularly scenic bush and cliff views. The route rewards experienced riders with solitude and heritage sites while demanding self-sufficiency due to limited services.
Heritage elements include the Moki Tunnel, often called Hobbit’s Hole, and remnants of early settlement and railway history. The highway was fully opened in 1945 after decades of construction.
Cycling the Route
The full distance suits multi-day tours rather than a single-day ride. Riders typically allow two to three days to enjoy the scenery and stops safely. Mountain or touring bikes with wider tyres handle the gravel sections best. Carry tools, spare tubes, food, water, and weather protection at all times.
Key challenges include the four steep saddles and narrow roads shared with occasional vehicles. Traffic remains light, but riders must stay alert on descents and through the single-lane tunnel. Many cyclists combine the highway with the Mountain to Sea Trail connections for a longer adventure ending in New Plymouth.
Day Trips from New Plymouth
The Forgotten World Highway makes an excellent full-day scenic drive from New Plymouth. Visitors commonly travel to Stratford then continue along SH 43 as far as Whangamōmona or the Tangarakau Gorge before returning, covering roughly 200-250 km round trip depending on turnaround point. The route showcases volcanic landscapes, historic sites, and rural Taranaki within a manageable day.
Many travellers stop at Strathmore Saddle for panoramic views or visit Whangamōmona for the republic passport stamp. The drive takes three to four hours one way at a relaxed pace with photo stops. Cyclists seeking shorter outings can ride sections of connecting routes such as Junction Road to Purangi instead of the full highway.
What Visitors Often Say
Reviewers describe the highway as spectacular and remote, praising the dramatic saddles, gorge scenery, and sense of adventure while noting the need for careful driving or riding on gravel and narrow sections.
Many appreciate the historical stops and quiet atmosphere, recommending it as a highlight of Taranaki visits but advising good weather preparation and allowing extra time for the winding terrain.
