Day 3: today we took the bus to the old San Juan. Loved the bus ride which took us through the areas normally tourists would not see. PR is quite diverse but all is surrounded by different shades of emerald or blue ocean. Old San Juan is a really interesting town, walled city and quite walkable. One of the best features is the free trolley bus ride that makes it easy to visit the town under the hot Caribbean sun. Narrow cobble-stoned streets were very charming. The fort was very impressive. The narrative kept saying we were looking at the same view the Spanish soldiers were looking at. We had some delicious authentic Puerto Rican lunch. Kids loved feeding the doves.
