The Patagonia Eco Domes is such a special place right at the base of Mt. Fitz Roy. You couldn't stay closer to the mountain unless you were really camping. The eco domes are pretty luxurious - so clean with tons of space for luggage. Beds are so comfortable and spacious. The bathroom and shower were amazing, too.
We were there end of Feb with very warm weather and not much wind, but you have to light the fire in your room at least every 2 hours to avoid waking up to the cold, but it's totally manageable so worth it. Hearing the crazy wind at night was such an experience. And we loved disconnecting from the world and wifi! Highly recommend the deluxe double room and the triple room for those with a bigger family. And recommend waking up at sunrise to see the sun hitting El Chalten - such a special view.
The location is perfect for the Laguna de Los Tres hike as it's right on the El Pilar trailhead, saving you at least 2 hours of extra hiking, which we were so thankful for!
Food and drinks were superb - alcohol, beer, wine (everything you could want). The croissants at breakfast were incredible, tasted homemade. The packed lunches for our hike were amazing and ample - the empanadas were yummy. Dinner was different each night and really good.
The staff goes above and beyond for you. Their English was perfect. We especially loved the younger female who worked at the front desk and checked us in (can't remember her name but it's her 2nd season at the hotel). She was so bubbly and helpful.
