Venture on the mighty Amazon River aboard the elegant and luxurious Delfin I river vessel voyaging into the Pacaya-Samiria Reserve, five million acres of protected, flooded rain forest bursting with biodiversity. Depending on water levels you navigate narrow tributaries by skiff and hike on foot through the terra firme forest. Along with our local, naturalist guide, you disembark from the ship regularly to discover areas rarely seen by other travelers: canoe the calm waters of a remote lagoon, keeping your eye out for the 170-lb endangered Paiche fish and vibrant parrots; swim in the El Dorado river with the legendary pink and gray dolphins; head out on a Pacaya River night safari amongst the illuminated eyes of black caiman and flickering fireflies; and spend an afternoon the Yanallpa community, learning about their medicinal plants and how they harvest fruit. Enjoy world-class, personal on-board services and amenties, spacious private suites with panoramic views, supremely fresh local cuisine, and knowledgeable naturalist guides. After a gourmet dinner on board, watch the moon rise over the rainforest from the peaceful rooftop deck.
