Tours for tips is great! They really emphasize the price is what you feel the tour is worth. The English speaking guides were very knowledgable about the city and made us feel much more confident to explore Valpariso on our own. I would recommend doing this tour as soon as possible once arriving to the city because it shows you how to access all the neighborhoods, how to use the local transportation, and how to manouver the complex streets. Would recommend this waking tour to anyone visiting Valpariso!
