I was on a 22 day trip with G Adventures. I had a few days to explore on my own before and after.
I began in Bogota. It is not as hot and humid as other places and has its own micro climate, so the weather can be very changeable. This is due to it being surrounded by mountains. I was lucky to have good weather the entire time. There is a lot to see and do in Bogota.
Beyond Colombia offer free walking tours and free food tours twice a day. I went on both, an excellent way to get orientated, learn about past and present history and sample some of the local delights. First was the food tour, a great way to spend an afternoon. There were a fair few people on the tour and lot of nationalities, Canadian, Belgian, German, Australian and, South Korean.
Most of the food was not in the slightest bit healthy, fried and laden with carbs and calories. They also have some strange combinations. There was something that was similar to a waffle that is topped with caramel and cheese. Remarkably not as bad as it sounds. Mick Jagger and the Stones played a concert in Bogota and he purchased a waffle from one of the carts. The next day the vendor had a picture of him on the front of his cart. The next week lots of carts had Mick Jagger pictures on them, all claiming they had sold the waffle to him.
