Bonito is generally considered to be reasonably safe, even at night. However, it's advisable to stay in well-lit public areas, avoid quiet and deserted places, and always be aware of your surroundings. It's a popular tourist spot, so most areas are frequented by people until late. But as always, stay smart and take the usual precaution measures you would in any other destination. Public transportation is also generally safe and reliable, but again, late at night it's recommended to use a taxi or ride-share instead of walking.
