My husband and I just returned from a two week vacation in Buenos Aires and our day at Estancia Los Dos Hermanos was absolutely a highlight!
Neither of us have horseback riding experience, but by the end of the day we were both galloping with confidence.
It was lovely riding the calm horses and observing the natural beauty of the land. We saw owls and parrots along the way and other ranches nearby. The sun came out in the afternoon and we were all enjoying the warmth of the sun.
The staff who work the estancia are #1 in their care and professionalism. We were very well taken care of and the food and drinks were extremely generous and the quality was excellent.
The car ride took about 2 hours from B.A. in the morning because of traffic but the return was about 1.5 hours. We didn't spend the night, but saw the rustic cabins and they seem great.
I don't think anyone would be disappointed if they go here.

We have never ridden horses so were somewhat reluctant but turns out that most other people who came on our day were equally inexperienced - it really doesnt matter as the horses here as so well trained that you have nothing to fear! The Estancia is very picturesque and is a great escape from BA - we had excellent weather and the light on the fields and trees was very beautiful. Riding was not really the highlight for me (v sore afterwards!) but im so glad we went as it was just great to be out in the countryside seeing another part of Argentinian life. Our horse guide Alexandro was extremely knowledgeable and helpful - and best of all was the lunch - 3 courses of fantastic bbq meat! I think out of the (many) meals we had in Argentina this was right up there - i know food tastes better outside but it was also due to the delicious meat and the great outdoor bbq - very succulent and smoky - YUM!!!! we paid $135US which included a days riding (about 3 hours split over 2 1.5 hr sessions), lunch, dinner (also yummy!), accomodation (nice - quaint - self contained house - open fire, rustic furnishings - not 5 star but really comfortable and felt quite authentically gaucho rather than a tourist version (I could be completely off here and real gauchos might scoff but the whole place felt like the real mccoy), and breakfast (typical forgettable argenitian one - but you will still be full from dinner). The driver was extra - $58USD each way from BA to Estancia. Would recommend including an overnight stay (one is plenty unless you are really into horseriding) as it was lovely to be there at sunset/
sunrise with the animals/peace and quite. It was a wonderful day - beautifully relaxing countryside and good to be doing something different on holiday (makes a change from pounding the streets to look at tourist attractions/find the next great meal), Highly recommended!

This is an excellent estancia to visit for the day to get out of the polluted capital and enjoy some fresh air. Four hours of horse back riding and an amazing asado (barbeque) makes for a memorable Argentinian experience. The staff are very attentive and keep close to beginners on horseback. For advanced riders, there is lots of cantering and the scenery is picturesque. You will no doubt catch glimpses of burrowing owls and native birds.

Dos Hermanos is a great excursion both for visitors and expats living in Buenos Aires. It is a horse lover's perfect retreat. Cabins are also available for rent for anyone wanting a longer stay, and also a nice option for families or a group of friends.

Great horses, warm and accommodating owners and fabulous food , what more can you ask for?

Getting away from the hustle of the city and spending a day at this estancia is a treat. You'll be picked up for about $120 rt so try to arrange it with another couple. Bonnie, the gracious guide will great you with wine and cheese. Unfortunately, it's succumb with flies, but you'll try to overlook it because of her graciousness. Next, you'll be fitted with gear and ride the beautiful trails in an estounding setting.

You'll feast on a variety of meat, salad, and dessert. Again, grab quickly before the flies become overwhelming. (you'd think they'd use Citronella candles or netting.) You'll then ride again and do some trotting.

Later, you'll relax on hammocks or take a swim. You'll be entertained watching the well taken care of dogs, and pity the malnourished cat with her hungry kittens, that must find food on their own. Many of us fed them our lunch.
Aside from the flies and starving cats, you'll be happy you spent a day there.
