Tips for Visiting Batu Islands

  • Ferry schedules from Sibolga or mainland ports can change with weather - confirm departure times locally.
  • The islands are known for traditional fishing communities and local ceremonies; observe respectfully and ask permission before photographing people.
  • If exploring by boat, bring a portable charger - phone coverage is intermittent and long days at sea drain batteries.
