San Jose, Costa Rica is a special place where one can surf the internet on a cell phone while simultaneously buy eggs from a man pushing a cart in the street. It's a meeting of old and new, east and west, north and south. This makes for lots of interesting discoveries as you explore the city.
Tourists may read it is best to get in and out of this city as quickly as possible to enjoy all the nature Costa Rica has to offer. I however argue that one solid day should be passed here. There is a lot to learn that will provide greater context to Costa Rica's culture, food, transportation and relationships to the rest of the world. And the more you know about a place, the richer your journey.
