The next morning we traveled back downriver to Posadas Amazonas. The journey was much quicker on the river as we traveled with the current. That afternoon we took a final muddy walk through the rainforest and prepared to say good-bye. I was not going to miss the heat and humidity and already had more than my share of insect bites (over 30 at last count, despite the long pants), but I was thankful for the chance to glimpse this strange, magical world.
