Crossing the Argentina-Uruguay Border by Land & Sea

Learn how easy it is to cross the Argentina Uruguay border on a day trip or even longer. Read on for more info about crossing via land or sea.

Separated by the muddy waters of the Rio de la Plata are buzzy Buenos Aires, Argentina, and the historic Colonia del Sacramento, Uruguay. Fortunately, crossing the Argentina-Uruguay border is one of the simplest transits you can imagine. 

In this guide, we’ll run down how to cross from one country to the other, both overland and by sea.

Important Disclaimer: Though every effort has been made to provide the most current and up-to-date information, international border crossings and their entry and exit requirements are very much subject to change. Political factors, natural disasters and global influences can affect a nation’s borders with little warning. Be sure to check with your country’s embassy—and that of your destination country—before you leave for your trip.

How to cross the Argentina-Uruguay border by ferry

Despite sharing a 579-kilometer (360-mile) boundary demarcated by the Uruguay River, which forms the border between Uruguay and Argentina, the vast majority of travelers will transit between the countries via a ferry ride.

The reason is very simple—two world-class destinations share their closest point across the wide mouth of the Rio de la Plata.

So, instead of an eight+ hour bus ride or an expensive flight, most visitors are happy to take a ferry or catamaran to these vastly different cities. And since the ride lasts only 1-3 hours, many people make it a day trip, but we don’t recommend that.

The two destinations are the vibrant capital, Buenos Aires, and the charming UNESCO World Heritage village of Colonia del Sacramento

Each has its own draw, and thanks to the frequency of ferry services, you could hop on over the border for the day and still be back for a steak or empanada dinner. However, given all there is to see, it’s usually better to allot at least a night—if not more—in each city.

Steps to make the border crossing from Argentina to Uruguay by ferry:

1) Buy a ticket with one of several ferry operators

Numerous operators make the run between Buenos Aires and Colonia del Sacramento. Prices and levels of service vary, so pick one that suits your itinerary and budget.

2) Arrive early to go through customs

Even though there is usually very little wait time, you are still crossing an international border. So, give yourself enough time for officials to check your passport before you board.

3) Enjoy the ride

Depending on the type of ferry you choose, your trip will last anywhere between one and three hours. 

While on board, you can have a snack or drink at the bar or even a quick nap. 

If you’re returning from Colonia to Buenos Aires, you probably will want to stay awake to see the city rise up on the horizon.

4) Pass through Uruguayan immigration

Upon leaving the ferry, it shouldn’t take you more than a few minutes to pass through Uruguayan immigration and have your passport stamped. 

Now, you can explore the charming town or head to the bus station for a trip to Montevideo or Punta del Este.

How to cross the Uruguay-Argentina border by ferry

Remember earlier when I mentioned that these crossings are some of the simplest you can imagine? That’s because they are! 

To get to Buenos Aires, Argentina, from Colonia del Sacramento, Uruguay, all you need to do is reverse the above steps.

Yep, there are no exit fees, no visas (for citizens of most countries), and no proof of a return ticket—you just pass through customs and are free to explore!

Can you cross from Argentina to Uruguay by land?

Punte del Este Uruguay

The simple answer is yes. However, the access points for Argentina-Uruguay border crossings are not frequently traveled by tourists. But if you enjoy particularly long bus rides, it is an option and, fortunately, just as simple.

If you’re going the land route, you’ll likely use the Gualeguaychu–Fray Bentos border crossing. It’s approximately 230 kilometers (143 miles) north of Buenos Aires. A four-hour bus ride (2.5 hours if you’re driving by taxi or car). 

To enter Uruguay, you’ll need to get across the Puente Internacional General San Martin (General San Martin Bridge).

You’ll have to present your passport to leave and enter, but the only fee you’ll have to pay is the toll for the bridge. Once again, this is as simple a crossing as they come.

From there, you can travel several hours to Colonia (4.5 hours by bus/3.5 hours by car) or the capital, Montevideo (five hours by bus/4.5 by car).

What do I need to cross the border?

Below is a rundown of important info that comes with any border crossing. As you’ll see, there’s not a whole lot you’ll need to provide


No matter which side of the border you’re coming from, each needs to see your passport. Make sure you have at least one full page available for your entry or exit stamp. Though not mandatory, having at least six months of validity on your passport is always a good idea when traveling internationally.

Departure Tax

If you are crossing between Argentina and Uruguay by land or ferry, you won’t be asked to pay a departure tax. 

If you decide that you want to skip all that and travel by air, Argentina will add a $29 international departure tax, which is included in the price of your ticket.

A similar air surcharge applies to tickets from Uruguay to Argentina, with $31 added to the cost of your airline ticket.

Uruguayan peso

Cash in small denominations is not required, but certainly convenient for small purchases or paying the toll on the General San Martin Bridge.

In Argentina, they use the Argentine peso, and in Uruguay, the local currency is the Uruguayan peso. 


For citizens of the United States, United Kingdom, European Union, Canada and Australia, no visa is required for stays up to 90 days. If you wish to stay longer than that, see your local consulate for further information.

Entry Fee

You won’t have to pay an entry fee to enter either country. 

Safety Tips

There are no significant safety or security concerns for visiting Argentina or Uruguay. Still, you must always be alert to your surroundings and mindful of your belongings at any border crossing.
