Bypassing Ponce de León’s Fountain of Youth Archeological Park is like visiting New York City for the first time and skipping the Statue of Liberty. The park is located near where the conquistador first landed after spotting “La Florida” (“the Place of Flowers”) on March 27, 1513. Fifteen waterfront acres overlooking the Matanzas River and St Augustine Inlet provide a lush backdrop for an impromptu picnic lunch of brisket and burgers from Smoked Southern BBQ, a deceptively casual on-premises food shack run by a James Beard–nominated chef. After lunch, tour the grounds’ various exhibits, including a Timucua Indian burial ground, a blacksmith shop and the Fountain of Youth Spring House. And don’t forget to swing by the gift shop and snag a bottle of the spring’s fabled waters – while we can’t promise it will add decades to your life, it does make for a fun souvenir.
