2. Noches de Galerias

The Buzz -- This Tuesday night diversion is as popular with locals as it is with visitors to San Juan. As many as 20 galleries and museums open their doors after hours and invite the public to view examples of Puerto Rico's rich artistic tradition. After taking in such a dose of culture, the night is still young enough to practice the art of partying in any of the bars and restaurants that line the streets between the galleries.
