Excursions and itineraries are organised along the Rio Negro. Thanks to its high acidity, there are fewer mosquitoes, which makes the trip more enjoyable! As you explore its tributaries, you will get a glimpse of the numerous Caboclo communities which live along the rivers. A 5hr boat trip from Manaus takes you to the Anavilhanas islands, made up of more than 400 islands dispersed over 100km. This nature reserve is a prime place for birdwatching, and for spotting manatees and Amazon river dolphins.
