Coast view...

If it happened that you visit Puerto Rico....go to the west coast and not only San Juan....San Juan is not even of a quarter of beautiful as this area. To mention some places...Cabo Rojo ( Bahia Sucia), Aguadilla ( Crashboat), Isabela (Guajataca). Ah...don't missed the only tropical rain forest in a USA territory ( El Yunque).
Other places to visit....Culebra Island (Flamenco Beach which is ranked the third most beautiful beach in the world).
