Okay. I promised an update, then I completely forgot about it...

When I was in New Zealand, I did enjoy quite a few adventure activities, though they weren't necessarily scary.
First of all, going on the trip itself: first road trip ever, in a large vehicle and with only one driver, me (my boyfriend doesn't drive). I had no experience with large vehicles AND could not drive a manual car - I took some lessons before the trip, but I was scared to no end about driving in NZ. So I guess that's an adventure. It was really scary when we first got the vehicle (large campervan), but I got used to it very fast. We also took it on a ferry, and driving a car into the ferry was quite something...

So here's what we did in terms of adventure activities:
- black water rafting (you float through a cave on an inner tube, with just a small headlight)
- zorbing, which is a crazy/weird/innovative Kiwi activity, where you roll down a hill in a huge plastic sphere
- walked around geothermally active areas, where the Earth's surface is very very thin, and while we weren't worried, there were "DANGER" signs everywhere
- trip to an active volcano-island (White Island)
- swimming with seals, swimming with dolphins and whale watching (all separately)
- walk on a glacier
- lots of small and large swingbridges, and I went on a flying fox over a 110 metre long swingbridge
- and lots of other fun, but probably not so adventurous things

That's all I can remember at the moment...

no bungy jumping!?!?!

looks like fun. i haven't been black water rafting, but went white water rafting in NZ and Bali. scary stuff!

i have seen the zorbing on a travel show - that looks insane!

No, no bungy, that's not for me. I wanted to go on a hot air balloon trip, or sky diving, but it was too expensive.

I've gone white water rafting too, in Canada.

Zorbing looks insane? It isn't, really. It probably looks crazier and more adventurous than it actually is. Though maybe it depends on which zorbing you do... there is wet zorbing (just you and a bucket of water inside), and you slide all around the zorb... and there is dry zorbing, where you're harnessed inside the zorb, no water. I'd imagine that dry is a bit crazier, since you actually end up going round and round... I didn't want to get wet, so I wanted to do dry, but they weren't running it because of weather conditions, so I had to settle for wet. I got soaked, but it was SO MUCH FUN!!! I want to do it again and again, every day. Excellent de-stressor for me.
