Prince Edward County is located in Southern Ontario on a large irregular headland or littoral at the eastern end of Lake Ontario, just west of the head of the St. Lawrence River. This headland (officially named Prince Edward County in 1792) is surrounded on the north and east by the Bay of Quinte. As the Murray Canal now connects the bay to Lake Ontario across the only land connection, the county is technically an island.

Prince Edward County is an island community encompassing approximately 1,000 square kilometres (390 sq mi), with over 500 kilometres (310 mi) of shoreline with beaches and limestone rich soil.

Prince Edward County has become a vacation Mecca with Sandbanks Provincial Park, the world's largest freshwater dunes, and Ontario's newest VQA wine Appellation as the twin-centerpieces of the tourism industry. Hotels, Motels, Bed & Breakfasts are abundant and mostly occupied during the summer months. In addition, many cottages are available such as those offered at Sandbanks Beach Resort.

Prince Edward County in recent years has become a top culinary destination. With emerging artists and wineries around every corner, there is never enough time to take in all the region has to offer.

From the historic Black River Cheese Company which started operations in 1901 to the new LEED-certified, award-winning Fifth Town Artisan Cheese Factory, the ‘County’ as it is referred to, boasts of being both a tranquil and culinary destination hot spot.

The 'County' also holds the annual Great Canadian Cheese Festival. This festival, held at the Picton Fairgrounds in June, boasts outstanding cheese-makers from all across Canada offering way more than 125 artisan cheeses for tasting and purchase. The festival also includes non-cheese related artisan foods such as, various breads and condiments, wine, cider and craft beer as well as many other offerings.

With an increasing number of cultural activities — in part due to the emigration of top artists and chefs to the area – like the "Taste" celebration or "Six Barrels for Six Chefs", the County has created a niche in the new Creative Economy.

Events also include the Spring Birding Festival; Prince Edward County Authors' Festival; the County Jazz Festival, a summer event; the Prince Edward County Music Festival (a chamber music series) held on the same fall weekend as the Prince Edward County Studio and Gallery Tour; "Music at Port Milford," a summer music festival and school for string students from 12–18 years old, and an annual season of professional theatre produced by Festival Players of Prince Edward County.

Prince Edward County is within close proximity to top educational institutions in Kingston and Belleville including, Queen’s University, the Royal Military College of Canada, St. Lawrence College and Loyalist College.
