This was the center starting point, from here there are all kinds of different adventures to go on. The first was driving the little off-road cars around a track which ran about 5 miles. It was very narrow, so there was very little "freedom", but still it was fun driving down into tunnels, over suspension bridges and up steep hillsides in the jungle!
Next was the zip-lining. I had never done any zip-lining before, and sailing WAY above the jungle, hanging from a cable was incredible! Unfortunately, you are SO high up that they don't really take pictures of you way up there. Eric was a little freaked out, and a lot freaked out when we got to the tallest one which was 45 meters tall, but he jumped like a trooper especially when he realized it would be at least an hour walk back thru the jungle if he didn't!
There's a video, but it will have to be posted later.
Finally we did some underground swimming and rafting in caves full of stalactites. It was awesome!
