Under the rolling hills of the Hamilton - Waikato region lies New Zealand's most fascinating system of caves and underground sink holes.

This magical caving system was created by underground streams pushing through the soft limestone earth over thousands of years. The result is a labyrinth of caves complete with stalagmites, stalagtites and river systems; with walls covered in thousands of twinkling glow worms. There's a myriad of activities on offer, catering to all levels of adventure - choose from gentle boat and walking tours through the maze of caves, with glowworms to light your way and stunning cave formations to marvel at to the more adventurous blackwater rafting, abseiling and ziplining through the underground passageways.
