Iquitos is the largest city in the Peruvian rainforest, with a
population of 370,962. It is generally considered the most populous
city in the world that cannot be reached by road.
Located on the Amazon River, it is a mere 106 m above sea level even though it is more than 3,000 km from the mouth of the Amazon at Belém in Brazil, on the Atlantic Ocean. Iquitos has long been a major port in the Amazon Basin. It is surrounded by three rivers: the Nanay, the Itaya, and the Amazon.
The city can be reached only by airplane or boat, with the exception of a road to Nauta, a small town roughly 100 km (62 mi) south.
The climate is hot and humid, with an average relative humidity of 85%. The wet season lasts from around November to May, with the river reaching its highest point in May. The river is at its lowest in October.
A boat tour of Belén is a common tourist attraction. Belén is an area east of Iquitos that can be accessed by foot and moto-carro both in the dry and wet seasons. However, many of the homes in this area are tethered to large poles and float upon the rising waters every year, and some homes float year-round. Where the waters begin there are often a few men with their boats who transport locals and tourists for a small fee.
