Argentina and Uruguay are separated by the Uruguay River that flows into the Río de la Plata. At the height of Buenos Aires and Colonia, the Uruguay River joins the Paraná River and they make up the Delta of the Río de la Plata, recognized as the widest river in the world with about 219km

Often times, many tourists who visit Buenos Aires also want to visit Colonia and / or Montevideo, due to its proximity to our country.

Next, we are going to detail how to get to Uruguay from Buenos Aires.

How to get to Uruguay from Argentina

Of course, the fastest way to get to Uruguay from Buenos Aires is by crossing the River directly. For this, it is necessary to take a boat. There are several companies that perform the service and, some of them, offer one-day packages to enjoy the neighboring country.

Boat companies to go to Uruguay

Buquebus is the best known company and part of Puerto Madero, near Plaza San Martín.

It offers packages for a day to Colonia and Montevideo, including passage, excursions and lunch.

If you want to pay in cash you will need to go to the port of Buquebus or its offices located in different parts of Buenos Aires.

There are two options: Boats direct to Colonia and Montevideo; or boat to Colonia and bus to Montevideo. If it is to spend the day, the latter is not convenient because it takes about 3 hours.

The alternative is Colonia Express, a company that starts its service from La Boca. It is the cheapest company among the three, but it also does not have a direct boat to Montevideo, since you have to go by bus from Colonia. It offers complete packages and, also, it can be paid from the web or at its offices in the city.

      Hi Felicity! Thanks for writing! We do not organize day trips of Colonia, but you can check these companies: buquebus, seacat and colonia express.

      Colonia is really small so you can enjoy it by yourself and if you want to know the history of the town, they run tours so you can take it once you are there.
