WE booked a 16 day vacation in Argentina through Evaneos. The highlight of our vacation was a 3 day tour around Salta in the Andes where we had an excellent guide and visited some wonderful locations. We also visited Bariloche in Patagonia and had a guided visit to visit to Iguazu falls which I would highly recommend.
Our trip was well organised by Evanos and the local agent was very helpful. We had to re-book a flight (due to adverse weather) and this was handled smoothly by the agent in Buenos Aires.
