This service is designed for itineraries requiring a concise, high-impact excursion. The tour departs from Manaus on a private boat, navigating directly to the point where the dark waters of the Rio Negro and the brown waters of the Rio Solimões flow side-by-side without mixing for several kilometers. The service includes pickup and drop-off at the passenger's accommodation in Manaus, with guide included. The private modality allows for flexibility in departure times and a pace tailored to the passenger, avoiding the crowds of larger boats. It is ideal for photographers and those who want a more personal experience of this natural phenomenon.
