This genre stretches from iPhone apps to some of the world's most powerful narrative nonfiction, as modern explorers tackle journeys both interior and exterior.

Writers.com offer four modules. Longtime instructor Amanda Castleman teaches her classic Travel Writing: From Press Trips to Punctured Tires roughly four times each year. Students may then progress to Advanced Travel Writing with Edward Readicker-Henderson or Amanda's Ongoing Travel Writing Workshop (with occasional assistance from Edward when she's on the road).

Both instructors have won the genre's ersatz Pulitzer, the Lowell Thomas. The Society of American Travel Writers honored Amanda for adventure coverage (Calm As the Hurricane's Eye) and Edward for cultural tourism (Under the Protection of the Cow Demon and Everything is Illuminated). He's also netted multiple mentions in the Best American Travel Writing series.

Finally, Writers.com debuts a 12-week Travel Writing Master Class. Anchored by Amanda, it stars Edward, author and columnist Thomas Swick, NYU Instructor David Farley and Charyn Pfeuffer of the Global Citizen Project. Not sure if the master class is for you? Take our quiz to find out.
