I am a big fan of rum, but had never visited a rum factory before. When I heard that Flor de Cana has the best rum in Central America and runs a tour daily (with the exception of Monday), it made it to my list of "to do" in Leon.
There are tours that run to the factory, but they are super overpriced at USD40/head, of which half of that amount is used to cover transportation.
Latina Hostel suggested that I can make my way on my own, costing just a couple USD for a return bus trip. This was the instruction sheet I received from them. Super basic!
