When to Go
In general, the island's northeast coast—preferred by those seeking abandoned beaches and nature reserves rather than casinos and urban glitz—tends to be less in demand than San Juan. The exceptions are at Easter and Christmas, when Luquillo and Fajardo become crowded with local sun worshippers, merrymakers, and campers. Island festivals also draw crowds, but planning a trip around one of them will give you a true sense of the region's culture. Be sure to make reservations well in advance if you're visiting during high season, which runs from December 15 through April 15.
