While winter may keep most of us indoors, there is still plenty to do in Cordoba that has to do with extreme sports. Hiking and fishing are just a few of the things that aren´t as weather contingent as you might think. Corodoba is such a cool place and the areas surrounding Corodoba are even more beautiful so you should take advantage of some space and get outside! The winters are clear and sunny for the most part here in Argentina so its a great time to see the outdoors.
Theres a hostel site I know of, and sure, they give some great info on hostels but they also have some info on extreme sports in cordoba so check it out. Its really great: http://www.cordoba-hostels.com/
