Learning about a culture through its cuisine, art, and history can be fun, but few things teach you more about the people that you are visiting and their attitude toward life than learning to dance with them. At Salsa Caribe (Plaza Casa Linda, tel. 809/880-4609 or 809/977-1795, www.salsacaribevent.com ) you can take lessons in salsa, merengue, bachata, Dominican son, reggaeton, cha-cha, and mambo. Other fitness classes are also available. Classes run US$10 for 55 minutes, but packages can be tailored to your level and according to your length of stay. Packages of private lessons can be arranged in any combination of dances. Dominicans rarely hear music and sit still. Learning to dance to merengue, bachata, or even salsa will give you great insight into the culture you are visiting.
