We did the boat tour to Estancia Cristina, followed by the 4x4 drive to the vista point, lunch, and tour of the local family museum. We liked it, but didn't love it. Here is our experience - your mileage may vary!
* Boat trip: it takes a bit over 2 hours from the dock to the farm on the way there.
There are gorgeous icebergs on the lake as you sail along, and the boat goes slowly to allow for pictures. The same ride on the way back was closer to 1.5hours. Boat is comfortable, mostly with indoor spaces to watch the view from behind the glass. Bathrooms on board (very clean on the way out, not so much on the way back), coffee and croissants available.
* 4x4 ride: once on the other side, groups are split by activity type (you're given a color-coded bracelet..). We had the 4x4 excursion, and were happy that we were assigned to do the trip before lunch vs. after it. The 4x4 are minibuses retrofitted with 4x4 suspension and roll bars. It's small, stuffy, and bumpy, going uphill non-stop for about one hour (not something I'd like to do on a full stomach!).
Once at the top, you walk about 20min to a gorgeous vista point. When we were there, the wind was very, very, very strong, which made it for a tough and cold walk. We were told that those conditions are quite common during the Summer. At the top of the hill, you get an expansive view of the glaciers around. We spent about 10-20min at the top and then had to move back to the minibus as a group. Tip: dress warmly!
Finally, you descend the same hill back to the flats, for about another hour. No bathrooms available throughout this whole part of the adventure.
* Lunch: Lunch was a set menu, with farm-like food and local wine. It was tasty and relaxing. We wished we could have hung out a bit more and chilled after lunch.
* Tour: After lunch, we were ushered to tour the family museum on the property. It is interesting enough, but the tour was long and crowded with over 15-20 people circling one of the guides that delivered the information somewhat mechanically.
And then it was back to the boat.
It is a LONG day in a large, organized tour following a tight schedule. The main highlight being the view from the top of the 4x4 ride. Definitely beautiful, but the cost-benefit equation may have been a bit off for our party.
