The Historic Center of the City of Colonia del Sacramento in Uruguay is a perfectly adequate World Heritage Site, but, as has been intimated by other reviewers here, it would likely not fall in the top tier for many WHS travelers. Like others, I visited the town as a day trip by ferry from Buenos Aires in March 2016. The weather was warm, which made the stroll around the historic cobblestone streets of the historic quarter rather pleasant. I appreciated the tile maps of the city found throughout the historic quarter, and also enjoyed the overhead views of the city from atop the lighthouse. Scattered around the quarter were several old cars that had been turned into artwork, and antique lamps were hung from the sides of many of the buildings. Before returning to Buenos Aires, my friends and I enjoyed a relaxing late lunch at a cafe overlooking the Rio de la Plata and some of the old city walls on the south side of the historic quarter. Although my visit to Colonia del Sacramento gave me an opportunity to see Uruguay for the first time, I think I'll have to return for a longer visit some day to get a better feel for the rest of the country.

Logistics: Colonia del Sacramento is accessible by ferry from Buenos Aires; the historic quarter is a short walk from the ferry terminal in Uruguay. Be sure to plan time to go through customs in both countries.
