The Amazon carries a greater volume of water than any other river in the world. The river drains a vast region that starts in the Andes, only 100 miles from the Pacific Ocean, and flows to the Atlantic Ocean. Its banks abound with tropical jungle and wildlife. The Lower and Central sections of the Amazon are treated as Ocean cruises on this site. The Upper Amazon River can be navigated to Riverboats from where it crosses Leticia’s Colombian border into Peru.

Lower Amazon and Delta

In this section of the river, the Amazon is so wide that cruising takes place on ocean liners. To find cruises on this section, we suggest you explore our ocean cruising site. The Amazon enters the Atlantic through an estuary of 150 mile wide, containing a labyrinth of islands that divide the river into branches.

Central Amazon

Starting at Manaus, 1000 miles from the sea, the Central Amazon River continues 1000 miles upstream to Leticia on the Colombian border. The character of the river changes westward after Manaus as the Amazon narrows, bringing its densely forested banks closer to the decks dramatically.

Upper Amazon

The Upper Amazon River roughly starts where it crosses the Colombian border at Leticia and then the Peruvian border to its source high in the Andes. It is navigable for ocean liners for as far as Iquitos in Peru passing the town of Pevas. Travelling between Leticia and Pevas, the Amazon becomes narrower still with its densely forested banks even closer to the decks.


The Amazon has two seasons, rainy and dry. The rainy season runs from December to June, with temperatures ranging from 23°C (73°F) to 30°C (86°F) and frequent, even daily, rains in April and May.

The dry season lasts from July to November, with temperatures from 26°C (78°F) to 40°C (104°F), with less rain, though showers are still possible.
