On the road to San Ramón is Matagalpa’s sweetest site. You’ve seen the chocolate bars by now, and if you know what’s good(-tasting) for you, you’ve also tasted Castillo de Cacao. Now tour the ‘castle’ where they mix the cacao with sugar, cashews and coffee beans. Call first to make sure they're working.
The tour (40 minutes) is given by ordinary staff who speak only Spanish. Matagalpa tour operators also offer a visit here with bilingual guides. A taxi from town costs US$1 per person.
