Morna — a fusion of Portuguese and African rhythms—is the signature sound of Cape Verde. Its bluesy melodies waft through the air of Mindelo, the nation’s cultural hub on the island of São Vicente where Holland America Line cruise ships dock. Find the beat along Mindelo’s cobbled streets lined with music clubs and colonial-era buildings, head to the top of Monte Verde for views over the Cape Verde archipelago, or travel up the coast to Praia Grande Beach for a taste of grogue, the local liqueur.
