Cave Stream Scenic Reserve

Cave Stream Scenic Reserve, on the road between Arthur’s Pass and Greymouth, is a dramatic limestone gorge carved by the Cave Stream. The main attraction is the 362-metre-long Cave Stream Tunnel, a natural rock arch that adventurous visitors can walk through – head torches and sturdy shoes are essential. Above ground, short trails lead to viewpoints over the stream and the surrounding beech forest, offering a taste of the West Coast’s raw, wild beauty.

Highlights & What to See

• Cave Stream Tunnel – Walk through the dark, echoing limestone tunnel (bring a torch and expect wet feet). The water is cold, so wear appropriate gear.
• Limestone Gorge – The stream has sculpted the rock into intricate shapes, with small waterfalls and pools perfect for photography.
• Beech Forest Walks – Short trails through ancient silver beech and mossy undergrowth, home to native birds like the South Island robin.
• Viewpoints – Lookouts over the gorge and the Canterbury Plains on a clear day.

Suggested Time to Spend

Allow 1–2 hours to explore the tunnel and short walks. The tunnel walk itself takes about 20 minutes, but you’ll want extra time to admire the gorge and take photos. It’s a quick stop en route between Arthur’s Pass and Greymouth, but don’t rush – the reserve’s raw limestone landscape is a highlight of the drive.
