A strong desire to travel is called wanderlust. If you dream of backpacking through Europe and then taking a quick spin through southeast Asia, you have wanderlust. The Germans call the strong urge for travel wanderlust, literally a desire for wandering.
Wanderlust is a strong desire to wander or travel and explore the world. Most of us experience the wish to visit faraway places once in a while, especially recently with lots of overseas trips being cancelled and replaced with staycations!
