We went on a zipline canopy tour through the rainforest. There were 12 cables strung through the forest, the longest one being about 1/4 mile long. It was a very cool experience. The only time there was any fear of heights was when we were on a platform high up on a tree. When going on the zipline, we were up above tree tops, so it didn’t feel quite so high. At the end, we rappeled down from the last platform after walking across a rope bridge.
