Both options allow for great wildlife viewing opportunities and a chance to see a variety of landscapes. Cruises allow you to visit more far-flung corners of the Amazon with changing scenery each day, plus you get the liveaboard cruising experience. Amazon lodge tours are more flexible, and your excursions are longer and less regimented, and you have more free time to enjoy the natural environment. Cruises will be the more expensive option between the two and generally require more days. One is not better than the other, they’re just different styles.
