Torre Monumental
This Renaissance clock is set on a platform 35 meters high with four staircases to access the interior. The four quadrants of the clock were built in English opaline and above each quadrant are five bronze bells. Atop the tower is an octagonal dome that is covered with layered copper. A weather vane that represents an Elizabethan three-mast frigate crowns the peak. A must see if you are trolling Buenos Aires!
This avenue is named after General Carlos María de Alvear, who had an outstanding performance in the heroic deed for freedom organized by General San Martín. Starting at the Plazoleta Carlos Pellegrini, it ends seven blocks away, where the Alvear memorial stands. Along the way you will view different residences and small palaces that survived town-planning changes. The most exclusive representatives of haute couture are on this avenue; maisons such as Versace, Nina Ricci, Prada, Louis Vuitton, as well as fine jewelries, shoe stores and leather garment stores.

Parque Nacional Nahuel Huapí is one of the jewels of Argentina. This is a spectacular area of lakes and rivers carved from ancient glaciers, majestic mountains, inviting valleys, meadows, Valdivian forests and wildflowers.
The name comes from the Mapuche language, where nahuel is tigre, or tiger, and huapí is isla, or island.
Spread over 2,927 sq mi (7,581 sq km) of Río Negro and Neuquén provinces, the park is an internationally known year-round destination for nature lovers and sports enthusiasts. In spring, melting snow creates waterfalls by the dozens. In winter, the mountain snows draw skiers, particularly at Cerro Catedral. The glacier at Perito Moreno and iceberg-dotted lakes elicit oohs and ahs.
This is not your usual port-of-call. There are no swaying palms, balmy breezes, tropical drinks with umbrellas, no vendors pursuing you along the quaint streets.
There are no cantinas with light-hearted laughter, no strolling musicians to serenade you at your table, no souvenir stores and exotic purchases.
After all, Deception Island is not a tropical island paradise, though it does have a Paradise Harbor. Deception Island is one of the islands in the South Shetland Island chain. It was formed by a volcanic crater, and when part of the crater collapsed, seawater rushed in the caldera and created one of the largest natural harbors (about 10 miles across) in the world. The harbor is protected from passing icebergs. 
If you have the opportunity to visit the Museum of Natural History in Mar del Plata do it!. It is located just off the beach road behind the Don Quixote sculpture. Very tiny aquarium displays with a few fish. A few small dinosaurs on display as well as some exhibits on fossils. Some gigantic prehistoric armadillos specimens. Some of the displays are empty though. A great series of bird displays featuring stuffed specimens of local birds. They also have a good display of bugs and a very good collection of local butterflyes.Nobody speaks english inside the museum but the specimens speak for themselves. Still a treat. Now out the back door and there was a large tent that held a hands on science room. Lots of stuff you see in US childrens and science museums. All hands on. A group of young teenagers are there to help with the displays. A lot of fun. Exhibits on sound, light, gravity, lots of optical illusion exhibits, electricity, etc. If you have been to a US museum of this type you will be able to figure out most of the exhibits and help your kids enjoy them. Reasonable price for admission. Great for kids and adults would find most of the displays interesting in the main building though without kids the hands on part could be a bit noisy.
I know this picture it's not that good, but what is really, and I mean really good, is the food and the service you get at the Los Inmortales (The Immortals) restaurant, on Corrientes Avenue, in
