Tatare Tunnels Walk

Overview

A quirky mix of West Coast rainforest and gold‑rush engineering, the Tatare Tunnels Walk is a 3.6 km/2.24 mi return out‑and‑back that most walkers polish off in about 1 hr 20 min. It’s mostly easy going with a short steeper, narrower section near the end—great for families or anyone who wants an adventure that doesn’t eat the day.

Route

From the end of Cowan Street in Franz Josef / Waiau, the track initially shares the first few minutes with the Callery Gorge Walk along an old 4WD road. It climbs gently before narrowing and steepening toward Tatare Gorge and the tunnel entrance. Expect lush, dripping-green forest with ferns and moss and the occasional peek into the gorge. Rough elevation gain is in the 120–130 m range.

Inside the tunnels

This is the fun bit—and where unprepared feet get a shock. The tunnel floor usually holds ankle‑deep, cold water. Surfaces can be slippery and it’s pitch black, so a headlamp/torch is essential. Turn your light off for a minute and let your eyes adjust to spot glowworms on the ceiling. The formed track ends just inside the far end of the first tunnel due to damaged structures beyond; it’s an in‑and‑out, not a through‑trip.

What to bring

Headlamp or torch (phone lights are weak), waterproof layers, and footwear you’re happy to soak—gumboots, sturdy sandals, or shoes that drain. Dry socks for the car are a morale booster. A small first‑aid kit and a dry bag for electronics are smart extras.

Safety and conditions

Weather flips fast on the West Coast. Avoid entering after heavy rain or if rivers are rising, and expect the water level to vary. Conditions and access can change, so check Department of Conservation track alerts before you go. No dogs.

Best time to hike

This is a solid short outing year‑round and can be a good rainy‑day option if levels are safe. For glowworms, you don’t need night—just pause inside and switch off the light. Earlier or later in the day tends to feel quieter around the tunnels.
