Buenos Aires is the most cosmopolitan of South American cities, and usually a great way to start or end a tour in the country. Any of these can be tailored - or we can add a couple of nights to any of the tours elsewhere.
We had a very good time in Argentina and Uruguay. The accommodations were good. The two guides we had were very good. The guide in Buenos Aires (Monica) was excellent.
The day at the Argentine ranch was very enjoyable. Our Grandson had a very good time there. The food was good and we liked the dancing.
