About this tour
When Em from our team tackled this Nelson Tasman ride, we found ourselves pedalling 50km through one of New Zealand's most scenic stretches — hop fields, native forest, quiet villages — all threading along a heritage railway line back towards the coast. The real drawcard is Spooner's Tunnel: a 2.4km passage through complete darkness on two wheels, lit only by your headlight, that feels properly wild. The route drops you at the top of the Tasman hills, then it's a long, mostly downhill cruise back to base near Tahunanui. Seven hours end-to-end, but the actual riding pace is relaxed.
Highlights
- Spooner's Tunnel in pitch black — genuinely disorienting and brilliant.
- Mostly downhill return ride eases tired legs after the tunnel.
- Heritage railway panels dotted along the route, adding local storytelling.
- Hop fields and native forest create proper contrast and colour.
- Shuttle handles the hard climb up; you just ride down.
- Small-group feel — personalised briefing before departure.
- Mix of sealed and gravel keeps the ride varied and engaging.
What to expect
The day kicks off with a 45-minute shuttle ride into the hills — time to chat with guides and get briefed on what's coming. You'll roll out at Spooner's Tunnel's entrance feeling fresh, then tackle the first stretch: mostly climbing through farmland and forest before the main event. The tunnel itself is surreal — completely dark, your lights creating a tunnel within the tunnel, and the sound of your tyres echoing off wet walls. It's not technically hard, but it's mentally intense for a few minutes.
Once you emerge, the vibe shifts. It's mostly downhill or flat back to Tahunanui, winding through small settlements and tree lines. The pace is social — you're not racing — so there's time to soak in the Tasman landscape. You'll finish near local pubs and cafes where a cold beer or cider feels entirely earned. The ride itself isn't brutally strenuous, but seven hours in the saddle demands a baseline level of fitness and familiarity with a bike.

Good to know
This is genuinely unique — Spooner's Tunnel is the longest cycle tunnel in the southern hemisphere, and riding through it is a story worth telling. The downhill return means you won't arrive shattered, and the heritage angle lifts the route beyond just pedalling. Small groups mean guides actually know your name and pace. E-bikes are available if your legs aren't confident over 50km. Good for older teens and adults; specialised infant seats mean families with tiny kids can join, though the tunnel's darkness and noise may spook some small children.
Seven hours is a proper day-long commitment. You'll need moderate cardio fitness — poor cardiovascular health, spinal injuries, or pregnancy aren't compatible. Food and water aren't provided, so you're buying lunch along the way and carrying your own bottles — budget for that. The tunnel is cold, wet, and dark; if claustrophobia is an issue, this will test you. Weather can swing in the hills, so pack layers. Early morning start means a pre-dawn shuttle. Peak season (summer) gets busier.
