Totara Valley to Tasman Bay Circuit
Marble mountains and forgotten valleys
The Totara Valley road winds through some of the South Island’s most isolated country, starting from the Cobb Dam and snaking through primeval beech forests toward the Tasman wilderness. This 40-kilometer loop connects remote valleys via the challenging Gouland Downs crossing, where marble karst country creates washouts and sinkholes that’ll test your line choice. The Aorere River crossing near the halfway point runs deep after rain — locals know to check conditions at Collingwood before heading in.
This is proper backcountry driving requiring high-clearance 4WD and recovery gear. The marble country between Mount Burnett and Mount Peel turns into axle-deep mud traps during wet months (May through September), making summer the only sensible season. No fuel or supplies once you leave Takaka, and cell service vanishes after the first valley. But you’ll earn access to pristine camping spots beside unnamed creeks and some of the clearest night skies on the South Island.

Frequently asked questions
Can a stock Hilux or Patrol handle this trail, or does it need a lift?
Stock high-clearance 4WD is the hard minimum, but the river fords and rocky climbs toward the marble passes will punish low-slung rigs without at least a modest lift. Lockers or a proper locking differential are strongly advised — don't attempt this one on open diffs alone.
When is the trail actually driveable and what closes it out?
November through March is your window — summer in the Southern Hemisphere. Outside that, snow on the upper passes and swollen river crossings from winter rain make it genuinely dangerous, not just difficult. Check DOC's conditions line before you go even in peak season, because river levels can spike fast after rain.
Do you need a permit to run this circuit?
No permit is required for vehicle access, but you're operating on Department of Conservation land so standard NZ backcountry rules apply — pack out everything, no fires outside designated areas. If you're camping overnight, check with DOC Takaka about current fire restrictions before you leave town.
What's the hardest section and what makes it ugly?
The river fords in Totara Valley are the crux — multiple crossings with rocky, uneven bottoms and current that varies wildly with recent rainfall. Water depth can go from knee-height to axle-deep or worse after a single storm. Walk every crossing before you drive it.
There's zero cell service out there — how far is the nearest fuel and should I carry extra?
Takaka is your last fuel stop and it's a real one — fill completely before you leave, and carry a minimum 20-litre jerry can for this 40km technical circuit where slow going burns more fuel than you'd expect. There's no bailout once you're in the valley, and recovery from here is a long, expensive day for anyone coming to get you.
