Colonia del Sacramento, Uruguay

“It gets all the Colonia attention, and rightly so. A grid of enchanting streets on a small peninsula jutting into the Rio de la Plata, this UNESCO-listed region is made for exploring. You won’t get lost (trust me, it’s too small for that), but you’ll have fun meandering from one plaza to another along cobbled & shaded streets, checking out pastel-coloured tile-and-stucco colonial houses, ye olde churches and ancient fortifications.”
