Bermuda is generally safe for solo female travelers, there is a low crime rate on the island. People are friendly and ready to help. Public transport is reliable and safe to use and most areas are well lit during the night. Practice usual caution, avoid desolated areas, and always stay alert of your surroundings.
Bermuda is super safe! The only notable thing is that men tend to catcall more than other places I’ve been, but in my experience it’s never been more than just a shout from across the street or a bike riding by.
