1989 Underworld Adventures founded.


Underworld Adventures is a cave trekking company, a quite common thing in New Zealand. It started at Waitomo and seems to have spread all over the islands. Located at Westport they offer cave trekking trips into various caves including the mandatory cave tubing trips, which means floating down a cave river with the inner tubes of truck wheels. It seems the venue is quite professional, it was founded by experienced cavers, and the tours are safe but strenuous. Physical fitness is required, for the wet tour you should obviously be able to swim and your camera should be water tight. Dry clothes to change afterwards and a towel are also recommended.
