Piranha fishing, caiman alligator wrestling, sloth and freshwater pink dolphin spotting, checking out the meeting of the waters and giant lily pads... Not to mention great food and excellent company. We lucked out. The two couples who were with us were hilarious. And they were Brazilian, which made me feel less like a dumb tourist paying for the Amazon experience.
Unfortunately I didn't get a picture of the ground lizards that live near the lodge. When it rains for more than three days straight, these lizards stay in their holes and EAT THEIR OWN TAILS to keep from starving. I don't like going out in the rain either, but this seems a bit extreme.
