A caravan is a group of people traveling together, often in a line of vehicles or on foot. Historically, caravans were used for trade, especially along routes like the Silk Road, where merchants transported goods across long distances. Today, the term can also refer to a mobile home or trailer used for camping and travel. In modern contexts, caravans are popular for recreational purposes, allowing families to explore different locations while having their living space with them. They can be towed by cars or trucks and come equipped with amenities like kitchens and bathrooms, making travel more comfortable.
