Go on an underground adventure at Nikau Cave


Head deep into the countryside at the northern edge of the Waikato, and you’ll discover one of the prettiest glowworm caves in New Zealand. 

Nikau Cave is nestled in the remote and rural Waikaretu Valley. 

Take a guided tour through a subterranean wonderland of limestone stalactites, stalagmites, giant pillars, fine straws, flowing shawls and rocks as big as houses. 

With narrow rock passages to crawl through and an underground stream where you will undoubtedly get wet, exploring Nikau Cave is an adventure.

But getting wet and muddy is worth it when you find Nikau Cave’s main, cathedral-like cavern adorned with a galaxy of twinkling glowworms.

For those who’d rather stay above ground, there are a selection of beautiful walking tracks that take in the native bush and a tumbling waterfall.
