The Amazon River is the world's largest river and flows through the world's largest rainforest. Its waters and those of its many tributaries support an incredible range of life: river dolphins, thousands of fish species, jaguars, anacondas, and countless other animals. The forest itself is a dense green expanse where rain falls regularly and the air stays warm and humid. People have lived here for thousands of years, and ancient rock carvings along the riverbanks tell stories of their presence. The river passes through several South American countries and connects different landscapes: flooded forests where trees stand in water, broad islands with their own wildlife, and table mountains that rise like giant fortresses from the jungle. Visitors can watch pink river dolphins, hike through thick forest, and boat along the brown waters. Places like Manaus show where different river channels meet and change color. The Mamirauá Reserve protects one of the largest flooded forest areas. In the Pantepui region, table mountains rise steeply, appearing almost otherworldly.
