A travel book can mean different things to different people. Some may call it a guidebook, a travelogue, or a memoir. Others may refer to it as a travel journal, a road trip diary, or an itinerary. Many travel writers prefer to use the term "adventure book" or a "voyage account" to describe their works. A few other synonyms for travel books include travel literature, travel guide, expedition chronicle, or wanderlust record. Regardless of the name used, travel books have one common purpose - to inspire and guide readers on their own journeys.
