Few jungle lodges do local relations better than Posada Amazonas. Founded as a partnership between Rainforest Expeditions and eastern Peru’s Ese’eja community, the 30-room hideout serves as a case study for indigenous-run eco-resorts across South America. Rooms are basic, with no electricity or hot water, but guests enjoy VIP access to the Ese’eja’s communally owned old-growth forest—a jungly magnet for giant river otters, red howler monkeys, and blue-headed parrots (three nights, from $430 per person, all-inclusive; perunature.com).
