Tunnel Beach

Just a short drive from Ōamaru, Tunnel Beach offers a dramatic coastal experience where rugged cliffs, sea-carved arches, and a historic hand-dug tunnel lead to a secluded sandy cove. Named for the 1870s tunnel blasted through sandstone by a local pastoralist to give his family private beach access, this spot combines geological wonder with a touch of local lore. The contrast of golden rock against the deep blue Pacific, especially at low tide, makes it a photographer's dream and a peaceful escape from the main tourist trail.

Highlights & What to See

• The Tunnel: Descend the steep stairs through the narrow tunnel – carved by hand – that opens onto a hidden beach, a unique piece of local history.
• Sea Arches & Stack: Marvel at the natural sandstone arch and the towering sea stack just offshore, sculpted by relentless waves.
• Fossil Hunting: Keep an eye out for marine fossils embedded in the sandstone – a reminder of the area's ancient seabed origins.
• Sunset Views: Time your visit for golden hour when the cliffs glow and the waves catch the last light.
• Nearby Ōamaru: Pair your visit with Ōamaru's Victorian precinct and its famous little blue penguin colony for a full day out.

Suggested Time to Spend

Allocate 1–2 hours for Tunnel Beach, including the walk down to the beach and back up. The track is steep and can be slippery, so take your time. Best visited at low tide when the beach is fully exposed and the tunnel is dry. Combine with a morning in Ōamaru or as a quick detour en route to Moeraki Boulders.
