The Jame' Asr Hassanil Bolkiah Mosque, a prominent landmark in Brunei, welcomes visitors outside of prayer times. Dress modestly, covering arms and legs, and remove shoes before entering. The mosque is generally accessible, though some areas may have limited access. Solo visits are common and allow for independent exploration, but guided tours can provide deeper insights into the mosque's architecture and cultural significance. There are generally no seasonal restrictions affecting visits. Expect to spend approximately 1-2 hours exploring the mosque and its grounds. The visit is free, but donations are appreciated. Remember to be respectful of worshippers and maintain a quiet demeanor within the mosque.
