The Port of Santos is Brazil's largest port, a string of terminals lining both banks of the Santos estuary on the Atlantic coast of São Paulo state, about 70 km from the city of São Paulo. It handled about 5.49 million TEU (twenty-foot equivalent units) of containers in 2024, which put it 37th in the world in Lloyd's List's One Hundred Container Ports ranking, and in 2017 it moved almost 130 million tonnes of cargo of every kind. It opened as a modern "organised port" on 2 February 1892, and it matters because it carries roughly a quarter of Brazil's foreign trade: it is the world's leading export port for sugar, orange juice and coffee beans, and the main gateway for the factories and farms of São Paulo, Minas Gerais, Goiás and Mato Grosso.
The best way to understand Santos is to follow a ship in. The port is not one harbour basin but a winding tidal channel, with the island city of Santos on the right bank and the island of Santo Amaro (the municipality of Guarujá) and the mainland on the left. The port authority's own area counts 66 berths spread over some 15 km of quay on the two banks, plus five private terminals outside it. What follows is a tour upstream along the Santos side, then back down the Guarujá side, with the landmarks a visitor or a deckhand would pass.
Ponta da Praia, Where Every Ship Turns Into the Estuary
The tour starts at Ponta da Praia, the southern tip of Santos, where the beach ends and the shipping channel begins. The neighbourhood's waterfront looks straight onto the channel, and in the cruise season people gather at the Deck do Pescador to watch cruise liners and container ships slide past only a few hundred metres away. The Terminais da Ponta da Praia are the most seaward berths on the Santos bank.
Here the city has its most visible problem. A car ferry links Santos with Guarujá across roughly 400 metres of water in about seven minutes, carrying more than 21,000 vehicles, 7,700 cyclists and 7,600 pedestrians a day; the overland route round the estuary is 45 km. A bridge has never been built because of the ship traffic below, and the idea of a tunnel is almost a century old: Governor Júlio Prestes presented one, inspired by New York's Holland Tunnel, in 1927. Survey drilling for an immersed tunnel of about 1.5 km finally began on the estuary bed in February 2025, with opening planned for 2031.
The channel itself is largely man-made in depth. The natural estuary is only about 6 metres deep, so constant dredging keeps it usable; by 2018 ships could berth at a draught of 13 metres. In February 2024 the port handled the biggest vessel it had ever received, the 366-metre MSC Natasha XIII, able to carry about 14,400 TEU, in an operation coordinated by the Brazilian Navy's São Paulo harbour authority and the local pilots.
Macuco and the Outeirinhos Sugar Quays
Heading inland along the right bank, the next stretches are the Cais do Macuco and then Outeirinhos, whose berths are split into the sugar terminals, the "Curva 23" terminals and a southern section. This is the only part of the port where the land itself was built out into the water. The area between warehouses 12 and 23, called Paquetá-Outeirinhos, was originally a bay; the Companhia Docas de Santos filled it in to create a straight quay deep enough for bigger ships, hauling stone from a quarry in the Jabaquara district on a railway laid for the purpose. The port's administrative headquarters still stand at one end of that landfill.
Sugar is the cargo that defines this stretch, and fire is its recurring danger. On 18 October 2013 flames spread along the conveyor belts of two Copersucar sugar warehouses, injuring four workers and burning about 180,000 tonnes of sugar; the charred sugar and firefighting water ran into the estuary and killed thousands of fish. In August 2014 another blaze destroyed 15,000 tonnes of sugar in warehouse X (terminal 19), run by Rumo Logística.
The company that built all of this, the Companhia Docas de Santos, held a 90-year concession from 7 November 1890 to 8 November 1980. It grew out of a group of partners led by the Rio de Janeiro merchants Eduardo Guinle and Cândido Gaffrée, and at its peak it employed around 15,000 people. It also built the Itatinga hydroelectric plant in the forest near Bertioga, finished in 1910, which still supplies power to the port more than a century later, with some of its original turbines in service.
Valongo, Where the 1867 Coffee Railway Met the Ships
Beyond Paquetá lies the Cais do Valongo, the oldest commercial heart of the port and the reason Santos grew rich. In 1867 the British-owned São Paulo Railway opened its line from Valongo station to Jundiaí, the first railway station in São Paulo state. Its engineers, including the young Daniel Makinson Fox, beat the 800-metre Serra do Mar escarpment with a cable-hauled incline, and the trains brought down the coffee of the inland plateau to be loaded straight onto ships. Coffee remained the port's main export until the Second World War, and millions of immigrants, above all from Italy and Japan, came ashore here before heading inland by rail.
The city paid a price for that trade. In the 19th century Santos was known as the "port of death" because of yellow fever and other epidemics in its swampy streets, and ships avoided the wooden wharves. The drainage canals designed by the engineer Saturnino de Brito, still a feature of the city, ended that era. Valongo station served passengers until 30 November 1995; restored in 2004, it now houses the municipal tourism office. The surrounding district, once one of the grandest in the city, is scarred by lorry traffic coming off the Via Anchieta.
Saboó, BTP and the Alemoa Tank Farms
Further upstream the quays turn industrial. After the Cais do Saboó comes BTP, the Brasil Terminal Portuário container terminal, and then the liquid-bulk terminals of Alemoa. The Alemoa district grew up on a mangrove swamp in the 1860s and takes its name from a German widow, Maria Margarida Kunem, whom neighbours called "a Alemoa" (the German woman). Today its container yards and tank farms press against the homes along the Via Anchieta.
Alemoa is where the port's worst fire began. On 2 April 2015 tanks storing fuel and liquid fertiliser at an Ultracargo terminal caught fire, and the blaze burned for more than a week. Contaminated firefighting water flowed into the estuary, heating it and starving it of oxygen, and thousands of fish died; the Brazilian Air Force and the airport authority Infraero helped fight it.
The rhythm of this bank is driven by what the port carries. In 2017, 47% of the tonnage was solid bulk (soy, sugar, maize, coffee, fertiliser), 39% general cargo including containers and vehicles, and 14% liquid bulk such as vegetable oils and petrochemicals. Containers have grown fastest, as the chart shows.
Across to Guarujá: Tecon, Conceiçãozinha and Ilha Barnabé
Crossing to the left bank, the character changes. The Guarujá side holds the Terminal de Veículos de Santos (TEV) for cars, the solid-bulk terminals of Conceiçãozinha, and Tecon Santos, which by 2007 handled about a fifth of all the containers moved on the Brazilian coast. The private company Santos Brasil won the privatisation of Tecon in 1997, committing an investment of US$250 million. Its productivity rose from 11 container moves per hour that year to 55 in 2008, and in 2009 it received the first Super Post-Panamax cranes in the Americas, able to lift two 40-foot containers at once. Its quay grew from 510 metres to 760 metres in 2001, and reached 980 metres when its Terminal 4 section opened in 2010.
Upstream on the same side, Ilha Barnabé sits in the mainland part of Santos municipality. Known in the 16th century as the island of Brás Cubas, after the nobleman who founded Santos in 1546, it has been a fuel and chemical depot since 26 January 1930, its tanks linked by pipeline to the Presidente Bernardes refinery in Cubatão. Outside the public port area sit five private terminals, among them DP World Santos, an orange-juice terminal run by Sucocítrico Cutrale and a Dow chemicals terminal.
The fires did not spare this bank either: on 20 October 2014 a blaze destroyed an entire Cargill sugar warehouse on the Guarujá side before firefighters stopped it spreading, with no one hurt.
Up the Piaçaguera Channel to Cubatão and the Serra do Mar
The last leg follows the Piaçaguera channel, a branch of the navigation channel that gives Cubatão direct access to the sea. It serves private terminals such as the Usiminas steelworks and Tiplam, a terminal of the logistics company VLI. The industrial districts of Greater São Paulo and the Cubatão petrochemical complex owe much of their existence to the port's proximity.
From here the cargo climbs the Serra do Mar. Road freight uses the Anchieta and Imigrantes highways, while rail is run on two networks by Rumo Logística and MRS Logística; inside the port, about 100 km of track is run by Portofer. Rail carries roughly 27% of the port's cargo and 53% of its agricultural cargo. Congestion on these routes is the port's long-standing weakness: the main road into the port has long had only three lanes, two in and one out, for an operation that runs 24 hours a day.
The way the port is run has changed as much as its quays. When the Docas concession expired in 1980 the federal company Codesp took over, holding a monopoly until Law 8,630 of 1993 turned Santos into a "landlord port": the authority now owns the land and channel while private operators lease the terminals. Codesp began trading as Santos Port Authority in October 2019, and in March 2020 changed its legal name to Autoridade Portuária de Santos. It works in a city of about 430,000 people (2025 estimate) where, as early as 1913, 22.7% of the working population laboured in the port, and where Brazil's first organised strike broke out in 1897.
Seen from the water, then, Santos is less a single harbour than a 15 km corridor linking Brazil's richest state to the Atlantic, from the ferries at Ponta da Praia to the steelworks at Cubatão.
