“The guide made the trip” is a comment heard from many tourists. Their knowledge of the area and language ability are very important features. However, what appears to be more important than these is their personality and responsibility as they often carry the whole show and you are with them for a week. There is a rough system in Galapagos of Naturalist ‘I’, ‘II’ or ‘III’, where ‘I’ is a licensed guide with limited knowledge and ‘III’ is the most knowledgeable. However, looking for guides by name is the most credible way to go. We double check on who the guide is before booking any cruise.
