That picture's taken in parque nacional torres del paine. I went down there and did the full circuit trek (took us 6 days) on the tail end of a month-long trip through Santiago, Valparaiso, Pichilemu, Pucon, and the Punta Arenas/Puerto Natales/Torres del Paine area.
Torres del Paine is awesome, but you should know it's a massive tourist destination. To handle the crowds, everybody has to stay on the trail (except for climbers w/ permits), camp at designated campsites (most of which cost money and feel like small towns) and no fires are allowed. These rules are all in place for good reason, but it does detract from the experience. Expect to see at least 90% foreigners while in the park. Lots of Aussies, Kiwis, Europeans, and Americans. I speak Spanish but it wasn't necessary for that part of the trip. The trail is marked well enough that a compass and navigation skills aren't needed in the least. Come prepared for crazy winds, sideways rain, and wintery nights and you'll be fine. Most campsites have a refugio (cabin-like lodge) that you can stay in for a pretty penny. don't do that! bring all your camping gear and it's a way better experience. Also be sure to do the full circuit trek rather than the abbreviated "W" route. The circuit's backside is beautifully open and lacks the crowds of the frontside In hindsight, the scenery was other-worldly yet I'd do more research and find a trek with less crowds and more of a backcountry experience.
here's a few quick shots i got:
Are you guys planning on heading down there for just the trek, or also exploring more of Chile/Argentina? There's such a variety that it'd be a shame to head down, hike for a week, and immediately fly back. The tourism system in Chile is so well set up that getting around the country is no problem, and hostels are reasonably priced and widely available. Buses are nicer than here, and way cheaper as well. Just don't to Chile for the food haha. Grab a travel guide and find regions you're interested in before diving deep in and finding exact towns. I'd recommend avoiding anything in big, bold letters of a Lonely Planet guide.
Anyway, there's so much to explain that I'm sure I missed a point or 50. Feel free to shoot me a PM or reply in this thread!
