We arrived at the Estancia La Estela from El Calafate. We happened upon the La Leona to check in, and then made our way 2km down a small dirt road to some of the most picturesque land you will ever see in your life. The reviews (which are quite good) actually understated the beauty of the vista.
The first full day we were there we took a horseback ride that included the company of three dogs as we walked through an ever-changing, alien landscape. We stopped after around an hour for the most authentic (and best) food we had during our entire stay in Argentina. We spent a few hours eating, drinking wine, and listening to some of the amazing tales of the Carlos (the owner of the Estancia).
The next day my wife and I were brave enough to take a hike up to the top of Fitz Roy, but unfortunately underestimated the amount of time it would take (we arrived back at the estancia at 1AM), and the availability of gas in this remote landscape. We managed to make it back with just a few kilometers of gas left in the tank. The next morning, Carla (who had just started there) and the owner were kind enough to arrange and provide us with some gas and a lot of understanding given the circumstances.
To nitpick: the only down-side was that the room was quite chilly at night, so make sure you use their extra blankets!
Through our time at Estancia La Estela we met some wonderful people, facilitated by the small capacity of the ranch. We also had a night where it was just myself and my wife. It was a really life-changing experience, and we hope to go back soon.
