San Juan, the capital of Puerto Rico, is historic, mysterious and alluring. There is plenty to keep you occupied on this Caribbean nirvana. Casinos dot the landscape waiting to take your money. The Bacardi factory will beckon you with free samples. El Castillo San Felipe del Morro ("El Morro") with its famous garitas, is a must have photo opportunity. Exotic wildlife awaits you an hour outside of town at El Yunque, the only tropical rain forest in the U.S. National Forest System.
