Prince Edward Island might be better known by its less known spots and from the stories that are passed from generation to generation that make it a land of enchantment. Some books that take this approach are:

Acadian Legends, Folktales & Songs from Prince Edward Island by Georges Arsenault.

Land of the Red Soil: A Popular History of Prince Edward Island by Douglas Baldwin.

Maritime Provinces: Off the Beaten Path: A Guide to Unique Places by Trudy Fong. This book is a nice find, it features those spots that only the curious and careful traveler will value and that the tourist will surely overlook: old villages, lighthouses, special beaches, farm markets, special street corners, colorful characters. It also contains suggestions for half day, day and week trips.

You can always take a look at the usual guides:
