With over four million miles of highway, the USA offers more road trips than anyone could tackle in one lifetime.

Here are our top 10 favorite drives: what are yours?

4. Florida’s Highway 1: Fly along breath-taking bridges and causeways across the Florida Keys, an archipelago that feels as close to Cuba as it does to Miami. Your final destination? Kooky, anything-goes Key West.
