The shortest distance between Cuba and the tip of Florida (Key West area) is about 90 miles (approximately 145 kilometers) across the Florida Straits. If you measure to the southernmost point of the Florida Keys, it’s typically cited as roughly 90–94 miles (about 145–151 kilometers). For air travel, the direct flight distance from Havana to Miami is about 230 miles (roughly 370 kilometers), with flight times around 1 hour. If you’d like, I can tailor these distances to a specific start and end point (e.g., from Havana to a particular Florida city) or provide a map-based visualization.
