PEI is divided up into regions or our Coastal Drives. Points East Coastal Drive, Central Coastal Drive which includes Green Gables Shore and Red Sands Shore and last but not least North Cape Coastal Drive.
For people who want to explore the whole Island, I like to suggest that they try to stay in the Central region and then they can go in any direction from there and still make it back to home base by evening. Or you could plan multiple accommodations and stay in each region for a couple days to fully enjoy everything PEI has to offer. I promise that you won't run out of things to see and do!
Hope to see you soon!
