"Sandra Farms, a working coffee farm in the mountains of Adjuntas, offers daily Trip to Origin tours where you can taste the coffee, learn about the island's history of production, and sample the housemade chocolate. There's pick-up and drop-off in San Juan, but you can also arrive at the farm—way up a very windy mountain road—on your own, whether you brave a drive or hire independently. Tour guides work on the farm, and can speak about the history of sustainable agriculture in Puerto Rico as a whole. No doubt you'll appreciate enjoy the view—and likely the chocolate samples, too." - Alicia Kennedy
