While Khulna is generally safe to visit, a moderate level of caution should still be exercised. The locals tend to be friendly and hospitable, and crime rates against tourists are relatively low. However, instances of petty crimes like pickpocketing and bag snatching can happen, especially in crowded areas. It's also important to respect local customs and dress modestly to avoid unwanted attention. Travel in groups or with a trusted local whenever possible, especially in remote areas or at night.
