By buquebus or hydrofoil
A truly worthwhile day trip from Tigre or Buenos Aires is by hydrofoil over the Río de la Plata to Colonia. Uruguay´s historical gem is a gently paced, friendly place, made even more relaxed by the cool breezes that come in off the Río de la Plata and tickle its sycamore shaded colonial streets.
Colonia del Sacramento
A visit to the historic center of Colonia del Sacramento is like a walk back in time. Founded in 1680 by the Portuguese, this old colonial town is renowned for its cobbled, windy streets and colorful houses reminiscent of old Lisbon.
Due to its colonial beginnings, the city's layout is different from the majority of Uruguayan cities. Its cobbled streets and houses alternate with small bars, excellent restaurants, art and craft shops, museums and a large yacht harbor.
Colonia is no secret to The Argentine people, so get in before the rest of the continent succumbs to its charm. The World Heritage-listed site of the Barrio Histórico contains treasures including the superb 17th-century Portuguese contraband port, La Colonia Portuguesa, and the fortress of Colonia.
