Well, maybe is not a must see but...notice the urban architecture in downtown Concepcion: it's mostly Bauhaus. Why? Because every time Concepcion was obliterated by a violent earthquake, it must be rebuilt; this was done several time since colonial times, but after the last earthquake which destroyed the city in 1939 (with a death toll of over 40.000 people), German architects -both local and called in- took over the task to rebuild (again) the city, and being Bauhaus the current trend back in the 30's, well, that was the result...

*Note that 1939's quake was NOT the strongest cataclysm that affected southern Chile; the worst registered earthquake in the whole history of Mankind was that of May 1960 in Valdivia (300km. further south), which killed many thousands of people, changed dramatically the local topography, sunk forests, dipped lakes and changed the course of rivers, among other things and a giant tsunami wave which sucked several coastal villages. Despite all that havoc, Concepcion was not affected at all by it.
From Concepción, one of the most impressive trips to do is going to the mountains of Alto Biobio, hiring the services of Trekaleyin (www.trekaleyin.com). Trekaleyin is an indigenous (Pewenche) organization that, through communitarian tourism, aims to share and give value to activities we have traditionally carried out since immemorial times in our summer highlands or veranadas, in the Andes Mountains in Alto Bio Bio. Trekaleyin brings together Pewenche entrepreneurs in tourism from four communities of the Queuco Valley, which are Butalelbún, Trapa Trapa, Cauñicú and Pitril. They include tourist guides, artisans, cooks, camping and cabins owners and horse owners, who are all part of our organization.
