Just back from a tour to Colombia. It was so interesting - and the people warm and hospitable. Highly recommended. Although it was a tour, we had several meals on our own, and it was also incredibly cheap. Best food: Peruvian restaurants, as Colombia not known for great cuisine. Meals in nice restaurant ran to about $10 (with a fruit drink - Colombians not big on wine yet). An Uber ride for 40 minutes cost about $5.00 in Medellin (a most interesting city - with some impressively progressive things going on).
The Colombians very much appreciate our visiting this beautiful country, and even if you only know a couple of words in Spanish, a smile will get you very far.
