Yes. Cuba is very safe. Visitors have little reason to worry about personal safety on the streets even in Havana. Cuba is not prone to violence and it has the lowest crime rate in all of Latin America. There are strict sentences on crimes committed against tourists, which is a large reason the crime rate is so low. Violent crime is virtually unheard of in Cuba. If, for any reason, help is needed, police remain a visible and friendly resource for travelers.
