For most of its length the river flows through the Purus várzea ecoregion.[3] This is surrounded by the Juruá-Purus moist forests ecoregion.[4] It rises among the Ucayali highlands, and is navigable and unobstructed for a distance of 1,133 miles (1,823 km) above its junction with the Amazon. It has a total length of approximately 1,500 miles (2,400 km), and is one of the longest tributaries of the Amazon.

The 251,577 hectares (621,660 acres) Médio Juruá Extractive Reserve, created in 1997, is on the left bank of the river as it meanders in a generally northeast direction through the municipality of Carauari.[5] The lower Juruá River forms the western boundary of the 187,982 hectares (464,510 acres) Baixo Juruá Extractive Reserve, created in 2001.[6] Since 2018 the lower portion of the river in Brazil has been designated as a protected Ramsar site.[2]
