Explore this remarkable wilderness on daily excursions by skiff, kayak, and when the water level permits hikes on dry land. Skim past giant lily pads afloat on black water lakes, and venture into the rain forest on narrow tributaries. Spot sloths and monkeys, including colored saddleback tamarins, noisy howlers, and shaggy-tailed monk saki monkeys. Watch for an astounding variety of birds, from tanagers and hummingbirds to parrots and endangered scarlet macaws. Look for signs of the massive paiche fish, the Amazon’s largest; rare pink dolphins; and indigenous piranhas.
