Nightlife in Viñales is a far cry from the bustle and beats of Havana. That being said, there are a few nice bars and a couple of atmospheric venues where locals and visitors get together for evenings of live music and dancing.
The most popular of these is the Patio de Polo Montanez located on the central square and part of the cultural centre mentioned above. There is live music almost every night and the venue enjoys a lively and welcoming ambience. Nearby, you can find the smaller Patio del Decimista which can get a bit crowded when a popular band performs.
At both places you should feel free to ask a local to show you some salsa moves, Cubans are generally great dance teachers!
