Rimutaka Forest Park Summit Road
Historic railway incline turned challenging 4WD route
The old Rimutaka Incline railway bed now serves as a rugged 4WD route across the Rimutaka Range between Upper Hutt and Wairarapa. Built in 1878, this engineering marvel used a unique Fell locomotive system to haul trains up the brutal 1-in-15 gradient. Today’s track follows the original rail formation through cuttings blasted from solid rock, past the remains of Summit Station, and through the partially collapsed Summit Tunnel. The route descends through native beech forest toward Cross Creek, with several original trestle bridge foundations still visible.
The track requires genuine 4WD capability for steep, loose sections and seasonal washouts, particularly on the eastern descent. Winter conditions can be treacherous with snow and ice above 400 meters. DOC maintains basic facilities at Summit Station site, but drivers should carry recovery gear, extra fuel, and emergency supplies. The historical significance combined with technical driving and Wellington region accessibility makes this a must-do for Kiwi 4WDers interested in industrial heritage. Gates lock at dusk, so plan accordingly.

Frequently asked questions
Can a stock Hilux or Prado handle the Rimutaka Summit Road without modifications?
A stock high-clearance 4WD like a Hilux or Prado will manage, but low-range is essential on the steeper incline sections. Lifted rigs with all-terrain tyres will have more confidence on the loose, eroded surfaces.
Is the Rimutaka Summit Road accessible year-round or does it close in winter?
The best window is November through April. Winter months bring persistent rain, snow on the tops, and heavily waterlogged tracks that can turn the route into a muddy mess — closures are possible after severe weather.
Do you need a permit to drive the Rimutaka Summit Road?
No permit or fee is required as of current DOC regulations, but check the Department of Conservation website before you go as track status and access conditions can change, especially after storm events.
What's the hardest section of the trail and what actually makes it technical?
The steepest pinch climbs the original Fell railway incline gradient — loose shale, off-camber ruts, and embedded rock make it punchy for a moderate trail. Traction control management and careful line choice matter more than raw power here.
Are there water crossings and how deep do they get after rain?
Yes, there are multiple water crossings along the route. After significant rainfall they can rise quickly and become genuinely hazardous — check conditions with DOC before departure and don't attempt it if there's been heavy rain in the preceding 24–48 hours.
