Why do people go to the Forgotten World Adventures Rail Carts?
The Forgotten World Adventures rail cart experience is popular with those looking for a unique a mix of heritage, history, and countryside. Once used for freight and passenger trains, this now-disused railway offers a rare glimpse into rural King Country. These self-drive rail carts in NZ allow visitors to pass through a landscape shaped by farming, forestry, and forgotten settlements, with regular commentary and stops that tell the stories behind each bend in the track.
Most people join a rail cart tour to slow down and see a side of New Zealand that’s easy to miss by highway. Along the route, travellers encounter more than 20 hand-built tunnels, picturesque bridges, and open farmland – all without the need for any special driving experience, as the carts are simple to operate and follow the track.
How long should I spend at the Forgotten World Adventures Rail Carts?
The time needed depends on the tour you choose. Forgotten World Adventures offers a range of itineraries, from short half-day journeys to multi-day adventures.
Half-day tours (around 3–4 hours) are suitable for those wanting a compact experience. These cover a section of the line and include a handful of tunnels and scenic highlights.
Full-day tours (7–10 hours) are ideal for travellers who want to immerse themselves in the region’s history. A popular option is the The Republic of Whangamōmona full-day tour, which includes a visit to this remote self-declared republic.
Multi-day rail cart adventures combine rail cart travel with other experiences, such as the Whanganui River jet boat combo, which adds a river journey to the adventure.
Travellers with a flexible itinerary might consider booking a longer trip, as these often include meals, overnight stays, and a broader range of landscapes.
What is the hidden highway in New Zealand?
The “Hidden Highway” refers to State Highway 43 (SH43), also known as the Forgotten World Highway. This 155 km scenic route stretches from Taumarunui to Stratford, winding through rugged terrain, farmland, native bush, and small historic settlements.
The highway is known for its dramatic curves, one-lane tunnels, and remote character. A highlight is the Republic of Whangamōmona, a township that once declared independence as a tongue-in-cheek protest against local government boundaries. Today, visitors can stop at the Whangamōmona Hotel and collect a novelty passport stamp.
Many rail cart tours travel parallel to, or intersect with, the Forgotten World Highway, making the two experiences a natural pairing for those travelling through the central North Island by campervan.
