Nikau Cave is one kilometre long, has a stream running through it and is in its natural state.
Most of the cave is open and spacious except for a ten-metre length, which must be crawled through.
A wide variety of stalactites and stalagmites can be seen including giant pillars, fine straws and flowing shawls.
The glowworms and their dewy threads may be studied up close. In the big, cathedral-like cavern they resemble the night sky.
The cave environment is fragile and visitors must help us preserve this special place by taking great care not to touch and damage formations or glowworms.
