Casa Bacardí

Casa Bacardí, across San Juan Bay in Cataño, is the visitor home of one of the world's largest rum distilleries — so prolific it's nicknamed the 'Cathedral of Rum.' The Bacardí family, which traces its rum-making to 19th-century Cuba, has produced here in Puerto Rico for generations.

Guided tours walk through the brand's history, the distilling and aging process, and the story behind the bat logo, typically ending with tastings or a cocktail-making session. It's an easy half-day from Old San Juan — many visitors ride the short ferry across the bay from Pier 2 and continue by taxi to the grounds.
