Hawaii is the only state in the country where theobroma cacao grows. As every chocolate connoisseur knows, the tree that grows the precious seed that becomes chocolate is the cacao tree. The Lydgates are on a mission to grow enough cacao on their family farm with the hope that one day they will produce an identifiable Kauai Homegrown Chocolate. For now, you can tour this organic farm (in addition to cacao, they grow vanilla, timber, bamboo, and many tropical fruits) and learn how chocolate is made,"from branch to bar," as they put it. The three-hour tour includes, of course, plenty of chocolate tastings. Reservations are required for the morning tour, which begins Monday, Wednesday, and Friday at 9 am. Children 12 and under are free.
