Parking
Start at the end of Cowan Street in Franz Josef. A field account described limited parking in high season, so walking from the village is a useful fallback.

Westland Tai Poutini National Park, WC
A short forest walk to a damp, hand-cut mining tunnel.
Overview
Tatare Tunnels Walk is a 2.8-mile (4.4 km) out-and-back from the end of Cowan Street, through forest and a gorge viewpoint to an old water tunnel. Allow about 1½ hours. Pick it for the unusual tunnel and its mining history; the tunnel is a short payoff at the end of a forest approach, not a long cave tour. The last climb is narrow and steep, and the tunnel is dark and wet underfoot.

Trail guide
The first five minutes share the Callery Gorge approach. It climbs gently to a terrace behind Franz Josef, past the town’s water pipes and tanks. After about ten minutes on an old four-wheel-drive road, the track rises gently, then drops to a view into Tatare Gorge. Turn left where the walks divide; the Tatare route continues toward the tunnel.
The last approach gets steeper, narrower, and rockier. Expect a more careful climb just before the entrance rather than a smooth stroll all the way.
The tunnel is unlit, with an uneven stone floor and water that can be ankle-deep. A torch lets you see where you’re placing your feet; a raincoat helps in the damp passage. If glowworms are showing, stop safely and give your eyes time to adjust before switching off your light. They’re a possible bonus, not a guaranteed display.
The track ends just inside the far end of the first tunnel. The historic system continues beyond, but the wooden structures there are damaged and aren’t part of this walk.
Pioneer miners cut a 500-metre tunnel system through the gorge to carry water to the Waiho terrace. The gold didn’t repay the cost, but Franz Josef township grew on the mining site. From 1911, sluice pipes supplied water to the Graham Hotel, and high-pressure water turned a Pelton wheel that powered a sawmill by day and town lights at night. A small hydro station used the tunnels from 1938 until a slip destroyed it in 1982.
Begin at the end of Cowan Street in Franz Josef. The small parking area there has been reported to fill in high season; walking over from the village is a useful fallback.
Bring a torch and raincoat. The floor is uneven and water may reach your ankles. Dogs aren’t allowed. The visitor route ends just inside the far end of the first tunnel; don’t continue into the damaged timber structures beyond it.
