Enter an ancient world of limestone arches and caves surrounded by dense rainforest. You'll find New Zealand's largest limestone arch as well as one that may just be the most picturesque.
  • Discover not one but two arches – which will be your favourite, the biggest or the prettiest?
  • Take a torch and explore a cave – what creepy crawlies will you find?
  • Walk to Mirror Lake – will there be a reflection?
