Metro Cave / Te Ananui Cave

Metro Cave is a limestone cave system in Paparoa with passages carved by the underground Ananui Creek over thousands of years. The network extends through different chambers and passages that reveal how water has sculpted the rock formations.

The limestone deposits formed about 30 million years ago when the region was covered by sea, and over time water carved out the passages we see today. The cave developed gradually as underground water dissolved the rock layers.

The name Te Ananui refers to the underground creek that carved through the rock over time, reflecting the relationship between flowing water and the landscape. Visitors experience how the natural forces of water shaped this underground world.

Access involves a short journey from Charleston followed by a ride on a vintage tramway through the bush before walking to the cave entrance. Wear sturdy footwear as the path includes uneven ground and some steps.

The cave features a partially flooded underground chamber where glowworms create a natural light show from the ceiling above. Cave weta insects live on the surrounding walls, small wingless creatures that have adapted to total darkness.
