To truly experience the charm of Prince Edward Island (PEI), you should plan for 3 to 5 days. A 3-day trip allows you to explore the historic capital of Charlottetown, visit the "Green Gables" heritage site in Cavendish, and enjoy the red sand beaches of the North Shore. If you have 5 days, you can add a scenic drive along the Points East Coastal Drive to see the "Singing Sands" at Basin Head Provincial Park or head west to see the North Cape Lighthouse and the "Bottle Houses." PEI is a place meant for a slower pace of life; more time allows for shucking fresh oysters, cycling the Confederation Trail (a 470km trail on an old railway bed), and enjoying local theater like Anne & Gilbert. For those looking for a comprehensive maritime tour, 7 days would allow you to see nearly every corner of the island without feeling rushed.
