Sandra Cesca, a long time PV resident and photographer has been operating Puerto Vallarta Walking Tours for over 10 years. Recently I had the opportunity to join her on the "Historic El Centro" tour. One thing that I noticed immediately was that there were numerous other tours happening around us and they were all groups of 20 or more. Sandra's approach is small groups with individualized attention. We went inside workshops and markets to see and meet the artisans and vendors
