Embark on a 4-day Amazon adventure in the Yanayacu Community Reserve within the Tamshiyacu-Tahuayo Regional Conservation Area (ACRCTT), a 1,600-square-mile (2,575 sq km) protected reserve in the Peruvian department of Loreto, upriver from Iquitos. This biodiverse area of floodable and upland forest is known for its extraordinary wildlife, and a 2003 rapid biology inventory by Chicago's Field Museum found more species of mammals and trees here than in any natural area of its size in the world. Cruise along the Amazon and Yanayacu rivers, explore the jungle on guided walks, and look for pink river dolphins, caimans, monkeys, and sloths. The experience also includes piranha fishing, visits to local villages, and sunsets over Moena Lake, with accommodation in a comfortable ecolodge surrounded by the sounds of the rainforest.
