Here's another suggestion if you'd like to explore a bit of the island outside San Juan. We went to Ponce in the south of Puerto Rico from Dorado and mistakenly took the ruta panoramico (scenic route) shorter winding route that took us through the mountains and lasted two and a half hours.
Ponce is the next largest city after San Juan with its' own airport and a world-class art museum, the Museo de Arte de Ponce which is one of Puerto Rico's treasures. We arrived a couple of hours before closing and were given a quick guided tour by one of the museum volunteers. She led us through the museum and pointed out the highlights of their permanent collection with the finale on the second floor to see Flaming June by Lord Frederic Leighton. The galleries are arranged in a peculiar way with modern art displayed alongside Pre-Rapahelite works which makes for an interesting visit. There is a lovely outdoor garden with sculptures and a cafe overlooking the grounds. It's a good day trip especially if you take the highway 52, which we did on the way back home to Dorado, which cuts the trip to Ponce by an hour.
