As for Chile, I do mention it in the last paragraph. This article only mentions destnations which Cactus offers. In Chile we have Santiago and Pucon. I diidn’t include Sanntiago with the cities because I don’t feel it is quite as vibrant as Buenos Aires, Bogota, or Mexico City. That is not to do down Santiago at all - I lived there for a year and it holds fond memories for me (I got engaged over a bottle of Errazuriz wine in Bellavista!) - but I feel if someone wants a Soouth American capital ciity experience I think they may be dissppointed with Santiago as it is very obviosuly influenced by the USA. It is almost more of an outdoor enthusiast’s destination wiith its proximity to Cajon de Maipo for trekking and rafting, the high Andes for climbing and the Pacific for watersports. Or it is a destination which is greeat for those who may find the culture shock difficult in other cities - unless you find yourself in a cafe con piernas! Another thing is that Chilean Spanish is quite hard to understand and spoken veery fast. It’s a modern and relatively boooming city, but not in my top 3 for a language course.
The other option in Chile is Pucon. I didn’t include it because it doesn’t fit into any of my categories. Also, because it’s such a tourist honeypot you may find it hard to practice your Spanish. However, it is set in stunningly beautiful landscape - all around you are the deep blue lakes, lush forests and snow capped peaks of Patagonia. For this reason it’s a great place to visit and use as a base for adventure but wouldn’t get into my top language holiday destinations.
