A quick snapshot of what this tour offers: You’ll spend a full day exploring the birthplace of the Amazon River, visiting the small town of Nauta, cruising along the Marañón River, and relaxing at the Sapi Sapi Lagoon. Expect a mix of cultural insights, wildlife viewing, and spectacular river panoramas. The tour costs $220, which includes transportation, a guided experience, a picnic lunch, and entrance fees — providing good value if you’re looking for a comprehensive day trip that combines nature and local culture.
What makes us particularly like this experience are the moments on the water, especially cruising on the Marañón River with its chance to see wildlife and the views of the confluence of rivers that mark the source of the Amazon. Also, the visit to Sapi Sapi Lagoon offers a peaceful escape filled with opportunities to spot animals like the taricaya turtle, adding an authentic touch to your Amazon adventure.
One potential consideration is the full-day schedule — it’s a long day, with about an hour of travel each way, so if you’re not a fan of early mornings or longer outings, this might feel a bit tiring.
