A neighbor of mine and I went "river shrimping" in a local stream. Just after sunset we hiked up a few kilometers of stream with a flashlight in one hand and a machete in the other, searching for the light's reflection off the shrimps' eyes. We saw a 6-7 foot boa constrictor slither out of the water, countless giant spiders. My favorite part may have been scaling the cliffs of two waterfalls, about 20-30 feet each - reaching from roots to vines. The bounty was delicious, needless to say.
