Though electricity has extended into even the most remote villages of Hoa Binh, life in this province still pretty much shuts down to sleep in the evening hours. As the Lonely Planet describes it, "Even the dogs seem mellow." Evening folk dance and music performances are occasionally put on by the local hill-tribe people, which you'll be able to catch if you're doing a home-stay or tour of a local village.
Otherwise, simply enjoy the stillness and serenity of the Hoa Binh night, and indulge in some stargazing while listening to the forest rhythms. If staying in the Mai Chau valley, visit the Veranda Bar at Mai Chau Lodge to sample its nightly beer and cocktail happy-hour specials and a decent wine selection. Those seeking more nightlife excitement head to the bright lights of Hanoi, just a few hours away by car.
