I still can't help Noruega in her search, but I wanted to post my first experience at an estancia.
On Dec 24th we went to
Estancia Don Silvano in Capilla del Señor (West-NW of BsAs -
http://donsilvano.com/estancia.html) with family from Italy. We do not have a car and we were looking strictly for a
dia de campo due to limited time. Also, since someone else was buying, price was also of concern.
In the end, there were not many options of Dia de Campo offering transportation. La Bamba in San Antonio de Areco looked promising, but cost 3 times as much as Don Silvano and doesn't arrange for transportation. Again, it was not my call but I am happy anyway.
We were picked up in Plaza San Martin, in front of the Plaza Hotel, at 9.30 AM, with a micros (other pick up points available, though). The estancia is about 80 km from BsAs and it takes 60-80 minutes to get there without traffic (on 24th Dec. the city was DESERT).
There were 20 seats of the micro, all filled. Later that morning arrived another micro with about 10 people. So in the end we were 30 guests that day, all foreigners (except my husband and MIL) from various countries - Japan, US, Australia, Brazil, Italy, etc. However, for Christmas they were expecting 130 guests!

During the travel from the City to the Estancia, a young lady explained the life of the gaucho, the typical argentinian stuff (empanadas, mate, boleadoras, el gaucho y la china, the dances of the gaucho, el poncho, el falcon, etc.), with pictures shared on board. The lady spoke Spanish and then repeated in English - though a bit rusty, it was understandable.
Once arrived we were offered a glass of wine and empanadas fritas (
yummy!), then the tour began. First,
horse riding. It is actually a small tour of the estancia on a horse, and there are 22 horses available, more or less. I didn't do it because of ethical issues. Then,
carriage riding. A 10 minutes rides around the estancia, the other way round. After this, we gathered in the garden and one of the young ladies explained what is
mate, where it comes from, and we had a mate sharing session. After mate, we went to the kitchen to
learn how to make empanadas. You assist, only. but can make questions afterwards.
There is a small (and
imo pricey)
talabarteria on site where you can buy souvenirs, leather stuff, alpargatas, ponchos, etc.
The estancia has several buildings, one with
rooms available to spend the night, the old mud oven, an old kitchen with old cooking tools, etc. I lurked into one of the guest room and I have to say that they are very simple and basic, so not everybody might like that style.
There are a lot of peacocks roaming freely in the estancia, a small pond with geese, ducks, flamingos, two rabbits, turkeys, guinea-fowls, lot of horses. There were some areas labelled for goats and sheep, but there was none in sight. The
granja was small, there is no animal petting.
At around 1 PM we went in the galpon for
lunch, which was a typical Argentinian lunch consisting of cream spread, chimichurri, bread, and potato salad, carrot salad with hard-boiled eggs grated, mixed salad with green salad, onion and tomato. Then they started serving
asado, from morchilla+chorizo, then chicken, and finally the best part, bife de chorizo, asado de tira, etc. During lunch they offered an entertaining session of
songs and
dances (the dances were SO GOOD), listening to classic Argentinian songs sung live by a young fella. The dancers danced typical gaucho dances (sorry I can't remember their names), and then tango. They closed the act with a display of boleadoras that I appreciated greatly.
They served a budin de pan with dulce de leche and coffee. The dessert was home-made and very tasty!
We left the galpon and went to the
pool, but after 30 minutes the gaucho show started. Basically, there are a gaucho and a china running on their horses and playing a gaucho game pin a circle hanging from above while horse riding). The gaucho then shows how to "tame" a horse (make it lie on his back and hug him).
After the gaucho show we were offered a
merienda consisting of
pastelitos and another salty fried snack I didn't grasp the name of, with mate.
Then it was time to leave (at around 4.30-5 PM).
I enjoyed my day and I think it was a comprehensive tour of the gaucho experience, more commercial and tourist oriented than authentic. I don't suggest spending the night there since all activities are scheduled for the dia de campo guests, and after they are gone, there is nothing more to do. They repeat the same tour/show every day.
