Delfin Amazon Cruises.

This family-owned pioneer of Peruvian river cruising takes travelers deep into the Pacaya Samiria National Reserve on three intimate, all-suite vessels designed specifically for the Upper Amazon. Accommodating just a handful of guests, the fleet—including the freshly renovated flagship Delfín I—acts as a floating base for exploring narrow tributaries via daily skiff excursions. Onboard, the design eschews generic luxury for local craftsmanship, featuring floor-to-ceiling panoramic windows and, in select suites, private terraces with plunge pools. As the world’s first Relais & Châteaux cruise company, the experience is highly personalized, pairing raw wilderness adventures with refined service and a dining program rooted in Amazonian flavors and locally sourced ingredients.
