Duration: 1.5 hours, plus travel to/from ferry terminal
Both Buquebus and Colonia Express offer ferry rides from Buenos Aires to Colonia and back. The Buquebus terminal is located in Puerto Madero, which is easily reachable by taxi or private transfer. Make sure to plan enough time to go through border control and bring your passport, since you'll need it to enter Uruguay. The Colonia Express terminal is located in La Boca and is also accessible by taxi or private transfer.
Colonia del Sacramento is a very small city. Once you arrive at the terminal you can take a taxi or private transfer (or even walk, in some cases) to your destination.
