We visited the Amazon rainforest as part of a Delphin cruise on a small ship (eight passengers). The boat was excellent, with a great staff and good food. We explored several areas and walked through the forest on several occasions. Our excellent naturalist pointed out birds and animals that were interested and nearly hidden from untrained eyes. We saw sloths, three types of monkeys, and more birds than I can count. The paths through the rainforest were well worn, but not too hard to manage. The ship provided us with boots so that we didn't get out shoes muddy. Overall, we had a great experience.
