In January 2003 I spent two weeks on New Zealands north island in what is a caver's paradise- Waitomo. The caves at Waitomo are all fairly similar- usually a vertical entrance, with an abseil down to stream level then follow the water either upstream or downstream. Here's a selection of the photos I took on my old Canon AE-1 SLR. I cave with Sydney University Speleological Society- their website can be found at http://www.ee.usyd.edu.au/suss/
