"I can speak to my soul only when the two of us are off exploring deserts or cities or mountains or roads." - Paulo Coelho
A large part of what makes road-trips fun are the various types of terrain they take you through. Be it winding hill-climbs, arrow-straight highways or beach-hugging coastal roads, each route is fun for a different reason. In our list, you'll find self-drive holidays that require you to clobber over sand and snow, and also drive up-and-down hills and across flat expressways.
