On the east bank of the Río de la Plata, 180km west of Montevideo, but only 50km from Buenos Aires by ferry, Colonia is an irresistibly picturesque town enshrined as a Unesco World Heritage site. Its Barrio Histórico, an irregular colonial-era nucleus of narrow cobbled streets, occupies a small peninsula jutting into the river. Pretty rows of sycamores offer protection from the summer heat, and the riverfront provides a venue for spectacular sunsets. Colonia’s charm and its proximity to Buenos Aires draw thousands of Argentine visitors; on weekends, especially in summer, prices rise and it can be difficult to find a room.
