Tunnel Beach, Dunedin: Sea Arches, Cliffs & Secret Pathways

Ever wanted to walk through a hand-carved tunnel that leads straight to a secluded beach surrounded by towering sea cliffs? That’s exactly what you’ll get at Tunnel Beach—a lesser-known wonder just a short drive from Dunedin, New Zealand. It’s dramatic, it’s moody, and it’s the kind of place that makes you feel like you’ve stepped into a fantasy film.

Why It’s Called Tunnel Beach

Back in the 1870s, a wealthy man named John Cargill commissioned a tunnel to be carved through the sandstone cliffs so his family could access the beach in privacy. Today, that same tunnel still exists—complete with moody lighting and ocean echoes as you descend. It’s dark, a little eerie, and absolutely unforgettable.

The Walk Down (And Up!)

The walk to Tunnel Beach is roughly 2 km return. It starts off with sweeping coastal views and gentle slopes, but don’t be fooled—it’s a steep climb back up. Going down takes about 15–20 minutes, but coming back up will test your legs a bit, especially after a day of exploring.

What Makes It a Hidden Gem

Unlike the popular beaches around Queenstown or Auckland, Tunnel Beach isn’t crowded. You’ll find rugged sea stacks, carved arches, crashing waves, and dramatic cliffs that feel almost too wild to be real. The combination of natural erosion and historic human touch makes it one of a kind.

Best Time to Visit

Late afternoon or golden hour is ideal for photography. The light hits the cliffs beautifully and casts a golden hue across the beach. But do check the tide times—this beach can disappear fast when high tide rolls in.

Things to Bring

• Good hiking shoes (it can be slippery when wet)
• Headlamp or flashlight for the tunnel
• Light backpack & water
• Grip-enhanced trail shoes (Affiliate)
• Compact travel flashlight (Affiliate)

Local Tip

If you're heading down on a clear day, bring a picnic and enjoy the view from the cliffs. But remember—take all rubbish with you, there are no bins at the site.

How to Get There

From central Dunedin, Tunnel Beach is just a 10-minute drive. Use “Tunnel Beach Track Carpark” in Google Maps. There’s space for about 10–15 cars, and signs marking the entrance.
