5 Best Sights in Side Trips from Buenos Aires, Argentina

An ornate colonnade leads from the Luján River to this Beaux Arts building, built in 1909 to house a social club and casino. It contains a modest collection of Argentine paintings by artists like Quirós, Castagnino, Soldi, and Quinquela Martín, as well as works portraying life in the delta. The real showstopper, however, is the beautifully restored architecture: a sweeping marble staircase, stained-glass windows, gilt-inlaid columns, and soaring ceilings conspire to form a microcosm of the fin de siècle European style adored by the porteño elite. A trim sculpture garden and flower-filled park surround the museum, which is best reached by walking along Paseo Victorica.

Mate drinking in Argentina is even more deeply culturally rooted than drinking coffee in the United States or tea in the United Kingdom. The mate gourd and the accompanying flask of hot water is ubiquitous throughout all social classes and age groups, whether one is sipping alone or sharing with a group of friends. The Museo del Mate is a great place to learn about the history of mate yerba—the shrub from which the bitter tea is made—and the sometimes very stylish mate gourds from which it's drunk. Many mate gourds, both antique and modern, are made from beautifully crafted porcelain or metal. Tours are available in English.

Although most visitors are into naval, military, or nautical history, this museum's collection will fascinate even those whose interests point elsewhere. The interior of the building, which looks like a hangar-size barn, is filled with paintings, statues, uniforms, and beautifully crafted model ships. On the grounds are long-retired planes from Argentina's aviation history, including a great example of a North American AT-6 "Texan" from 1939.

Italianate mansions, museums, restaurants, and several rowing clubs dot this pictureseque paved walkway and waterside park that curves alongside the Río Luján for about 10 blocks. To reach it, cross the bridge next to the roundabout immediately north of Estación Tigre, then turn right and walk five blocks along Avenida Lavalle, which runs along the Río Tigre.

The center of the action at Tigre is its picturesque market. Hundreds of stalls selling furniture, handicrafts, and reasonably priced souvenirs fill the area around the docks along the Río Luján. It's particularly busy on weekends (indeed, many stalls are closed midweek). Grab a quick lunch from stands selling steak and chorizo sandwiches.
