Excursions....
Mendoza
The city is famous for producing excellent Malbec wines and is one of the most beautiful and neat cities in the country. Nestled in the foothills of the Andes Mountain Range, the days are hot and nights are fresh.
The city may be accessed either by air or by bus. I can give you more information about this.
At one of the best wineries in Cuyo, Mendoza
You can go around several wineries on tours, tasting the wines produced at the vineyards and which have made this region famous worldwide.

This is a two-day overnight excursion where you can do a tour of the vineyards on one day and a trip to the Andes on the other where you can travel on the historical roads that climb into the mountain range passing all the stunning scenery on the way.

Rosario

National Monument of the Flag
Rosario is located to the south of Santa Fe, 4 hours north of Buenos Aires. Argentina has some of the most luxurious buses and have reclining seats and aircon. This is a charming city that offers great spas, restaurants and shopping
You can also take a 2 hour boat ride along the river. This is a great city if you want to get out of Buenos Aires and see another part of Argentina. This is very worthwhile.
Places of interest: National Monument of the Flag, Hipódromo, Provincial Historical Museum, Museum of Fine Arts, Astronomical Observatory and the Planetarium and the Florida Spa.
Estancia experience

The estancia
For a perfect day out of the city. I can thoroughly recommend an estancia about 1 hour and 15 minutes out of the city. This beautiful estancia offers a beautiful pool and activities including horse riding. A 3 course unch is provided and you can stroll through the fantastic grounds that offer peace and quiet away from the stress of the city. You can stay over night or enjoy just a day of relaxing.
