A travelogue is a book that chronicles the journey and experiences of a traveler.
Some examples:
In a Sunburned Country by Bill Bryson Medium Raw by Anthony Bourdain Lands of Lost Borders: A Journey on the Silk Road by Kate Harris Around the World by Matt Phelan Up: A Mother and Daughter's Peakbagging Adventure - Patricia Ellis Herr
A fun quick read that I finished today was 52 Days by Camel. The title comes from a sign that inspired the traveler rather than describing the journey he took through the Sahara.
