Planning 3 - 4 weeks to wander and explore. Also planning for Uruguay and Chile.
I am spending a few months in Argentina and plan to see the north in October before heading to El Bolsón in November. I would be happy to travel with anyone who shares my interest in exploring this region. I am basing my itinerary on the reverse of the lonely planet "northern loop" but will have some flexibility, starting in BA and heading to Iguazú Falls then on to discover the northwest. If you're a respectful person in the area during this time and want to meet up for mate, a few days, or the whole trip, send me a message.
I am planning to spend a week in Uruguay and a week in Chile as well, in case you're interested in joining me.
