Garrison is relatively safe as compared to other parts of Barbados. It is a tourist hotspot with many amenities aimed at visitors such as hotels, shops, and restaurants. The locals here are also generally friendly and helpful towards tourists. However, like any place in the world, it's necessary to use common sense and precaution. Always be aware of your surroundings, especially at night. Don't show off valuables in public, and keep a copy of important documents such as passport and IDs.
