The genre of travel literature or travelogue encompasses outdoor literature, guide books, nature writing, and travel memoirs.
One early travel memoirist in Western literature was Pausanias, a Greek geographer of the 2nd century CE. In the early modern period, James Boswell's Journal of a Tour to the Hebrides (1786) helped shape travel memoir as a genre.
Early examples of travel literature include the Periplus of the Erythraean Sea (generally considered a 1st century CE work; authorship is debated), Pausanias' Description of Greece in the 2nd century CE, Safarnama (Book of Travels) by Nasir Khusraw (1003-1077), the Journey Through Wales (1191) and Description of Wales (1194) by Gerald of Wales, and the travel journals of Ibn Jubayr (1145–1214), Marco Polo (1254–1354), and Ibn Battuta (1304–1377), all of whom recorded their travels across the known world in detail. As early as the 2nd century CE, Lucian of Samosata discussed history and travel writers who added embellished, fantastic stories to their works. The travel genre was a fairly common genre in medieval Arabic literature.
In China, 'travel record literature' () became popular during the Song dynasty (960–1279). Travel writers such as Fan Chengda (1126–1193) and Xu Xiake (1587–1641) incorporated a wealth of geographical and topographical information into their writing, while the 'daytrip essay' Record of Stone Bell Mountain by the noted poet and statesman Su Shi (1037–1101) presented a philosophical and moral argument as its central purpose. Chinese travel literature of this period was written in a variety of different styles, including narratives, prose, essays and diaries, although most were written in prose. Zhou Daguan's account of Cambodia in the thirteenth century is among the major sources for the city of Angkor in its prime.
One of the earliest known records of taking pleasure in travel, of travelling for the sake of travel and writing about it, is Petrarch's (1304–1374) ascent of Mont Ventoux in 1336.
