During Victorian times, young adults from wealthy families in England went on a Grand Tour. They traveled for extended periods of time as an essential part of their education - an essential part of their passage into adulthood.
They spent weeks or months in Paris, Switzerland, Italy - actually, anyplace that beckoned. The more adventurous traveled further than Europe and weren't actually on a Grand Tour. They were explorers. Many spent extended time in the Middle East, Africa, and Asia.
Here are some of the books about people who went on extended travels when traveling wasn't nearly as accessible as it is today. Here are some books that ignited my dreams. Some of them are not in electronic form, but are available in paperback at Amazon.
