Buenos Aires to Colonia Ferry: Times, Ports and the Visa Run
目次
Uruguay is an hour away by boat. That single fact shapes a lot of how people use Buenos Aires.
Some go for a day out. Some go because the tourist stay in Argentina runs to 90 days, and leaving the country resets the count. This page covers both, honestly.
The two routes
There are two destinations and they are not interchangeable.
Colonia del Sacramento
About an hour by fast ferry. A small colonial town with cobbled streets, a lighthouse and a waterfront. Walkable end to end in a couple of hours.
This is the crossing most people take. It is the shorter one, the cheaper one, and it works as a day trip.
Montevideo
Two to three hours direct, or a ferry to Colonia followed by a coach. The capital, and a full destination rather than a day out.
If you have one day, go to Colonia. If you have two or three, Montevideo is worth it.
Which port you leave from
This trips people up because the two operators use different terminals.
Buquebus
Buquebus leaves from the Terminal Fluvial in Puerto Madero, at Antártida Argentina 821. It is close to the centre and reachable on foot from Retiro in about fifteen minutes.
Colonia Express
Colonia Express leaves from a different terminal further south, on Avenida Pedro de Mendoza in La Boca. It is not walkable from the centre. Take a taxi or an app car, and allow more time than you think.
Check your ticket for the terminal name. Arriving at the wrong one means missing the sailing.
Getting to either is straightforward with the map, which shows live buses and the Subte lines. The Safety layer is worth a glance if you are heading to the La Boca terminal early or late.
How the border works
Both countries check you in the same building, one after the other, before you board. This is called integrated control and it saves time on arrival.
You will pass two desks. The first stamps you out of Argentina, the second stamps you into Uruguay. Then you board. On arrival in Colonia you walk straight off.
Bring your passport. A photo will not do. Arrive at least an hour before departure, more in high season.
What a day in Colonia looks like
The historic quarter is small. The lighthouse, the Portuguese street, the old drawbridge, and a waterfront where people sit at sunset. Two or three hours covers it at a walking pace.
Renting a golf cart is a local custom and takes you along the coast road beyond the old town.
Uruguay uses its own peso. Argentine pesos are often accepted near the port but at a poor rate. Cards work in most places.
The last ferries back are in the evening. Check the return time before you settle in at a restaurant, because the schedule thins out at the end of the day.
About the visa run
This is the part people actually search for, so here is the honest version.
Visitors from many countries can stay in Argentina for 90 days. Leaving the country and returning starts a new period. Because Uruguay is an hour away, some people cross to Colonia and come back the same day, or the next, to extend their time in Buenos Aires.
That is what happens in practice. Here is what to understand before relying on it.
It is not a right
Entry is decided by the officer at the border, each time. Nothing obliges them to admit you, and nothing guarantees a new 90 days.
Repetition is visible
Your entries and exits are recorded. Someone who has crossed several times with no other purpose is easy to identify, and questions become more likely with each crossing.
There is a legal alternative
Argentina allows a one-time extension of the tourist stay, applied for at the immigration office (Migraciones) before the 90 days expire. It costs a fee and it is the documented route. If your plan is to stay six months, this is the path that does not depend on an officer's discretion.
Rules change
Immigration policy in Argentina has moved several times in recent years. Anything written here is what applies at the time of writing, not a promise about next month.
If your stay is genuinely a long holiday, a day in Colonia is a good day out and the reset is a bonus. If you are building a life here on repeated crossings, look at what living in Argentina actually involves and consider the proper route.
Practical notes
Book ahead in December and January. The crossings fill up and prices rise.
The fast ferries are stable but the river can be rough in wind. If you are prone to seasickness, take something before boarding.
Luggage allowances are generous compared to flying, which is why the route is also used to move things between the two countries.
There is a duty-free shop at the terminal. This is where a lot of the cost difference between the two countries becomes visible.
Frequently asked questions
How long is the ferry from Buenos Aires to Colonia?
About an hour on the fast ferry. Montevideo direct takes two to three hours, or you can take the Colonia ferry and continue by coach.
Which terminal does the ferry leave from?
Buquebus uses the Terminal Fluvial in Puerto Madero, at Antártida Argentina 821. Colonia Express uses a separate terminal on Avenida Pedro de Mendoza in La Boca, which is not walkable from the centre.
How does the border check work?
Both countries check you in the same building before boarding. You pass an Argentine desk and then a Uruguayan one, then board. On arrival you walk straight off.
Do I need my passport?
Yes. A photo or copy is not accepted. Arrive at least an hour before departure, more in high season.
Is Colonia worth a day trip?
Yes. The historic quarter is small and walkable in two or three hours, with a lighthouse, cobbled streets and a waterfront. Many people rent a golf cart to see the coast road.
Does leaving to Uruguay reset the 90 day tourist stay?
In practice many people do this and are readmitted for a new period. It is not a right. Entry is decided by the officer each time, entries and exits are recorded, and repeated crossings attract questions.
Is there a legal way to extend the stay?
Yes. Argentina allows a one-time extension applied for at the immigration office before the 90 days expire. It costs a fee and does not depend on an officer's discretion at the border.
Should I book in advance?
In December and January, yes. Crossings fill and prices rise. Outside the summer months you can usually buy on the day.
