Hiking in Bariloche is easy because there are tons of refugios which are cabins in the forests that offer a place to sleep and eat. They’re mostly run by Club Andino, the local mountaineering club and it’s a great service because it allows you to hike for the day, spend the night, and hike out the next morning. A lot of places that couldn’t be managed as a round trip in a single day can be done by taking advantages of the refugios (important since I’m not carrying any camping gear).
Most of the hikes are easily reached by local bus from the city center, but on the advice of my hostel I decided to take a bus a few hours away to a park near Monte Tronador (Mount Thunder). This mountain is on the border with Chile and is named for the glaciers on the mountain which calve pieces off over a cliff. The sound of the ice falling down the cliff echoes through the valley as a low rumble that sounds just like thunder.
The climb to the refugio took about 7 hours and was up the whole way. I had sat next to a Spanish guy on the bus from Bariloche and we decided to hike to the refugio together. The path was a nice change from other hikes where it seems like every time you ascend 20 meters you then walk back down 10. The first 4 hours are a gradual switchbacking trail through a beautiful old forest with massive trees, wildflowers, small waterfalls, and lots of moss and lichen. Daytrippers can enjoy this area too because a local estancia (ranch) offers horseback riding and there’s a side path over to a glacier that still leaves time to hike back the same day.

Eventually we reached the caracoles (literally translated “the snails”) which is a 30-minute section that is extremely steep and made me glad my pack was nearly empty. Past this is the tree line and a couple of hours of hiking, marked by paint splashes, over large boulders and shale to the refugio.
The refugio is still a few hours from the peak of the mountain. It’s located in a gap between two glaciars and has some really nice views. From here there’s a menu of guided tours available to ascend higher on the mountain. We could have gone to the peak, to another refugio higher that has a descent route that cris-crosses the border (requiring advance permission from Chilean immigration), or just for a hike on the glaciers. These all require crampons, ice axes, and guides to prevent you from falling into crevasses though.

From the outside the refugio looks like a decaying shack, but inside it’s pretty nice. It has lots of wood paneling, almost a log-cabin look. It turned out the only other people that came that night were two German guys, so we had 4 visitors and 3 staff! The staff made made me a huge tenderloin steak with mushroom sauce and roasted vegetables, and I swear it’s one of the best meals I’ve ever had. The four of us also split a bottle of wine, so it was kind of posh for being so remote! The winelist had prices up to $450 ARS (about $115 USD). Dinner was $50 ARS ($12.50 USD) and to sleep was $40 ARS ($10). A bit expensive for Argentina, but given the challenges of operating the refugios it seemed fair.
It was interesting to talk to the staff about the logistics of running the refugio. They bring in supplies (including food) mainly by having horses bring them up the main part of the trail, and then having the staff carry them in packs through the caracoles and across the rocks to the refugio. I think the staff can probably do one packful in about 4 hours. Occasionally the Argentine military drops supplies by helicopter (fuel, building materials, etc) because they use the glaciers near the refugio to train for Antarctica. Hard work!
