The Cabot Trail, a scenic highway that winds along the island's northern coast, is one of the most popular routes for tourists. The full Cabot Trail is approximately 300 kilometres long and can be driven in one day, but it is recommended to allow more time to enjoy the many sights and attractions along the way.
The South Shore Road, which follows the coastline from Halifax to Yarmouth, is another popular route. This road is approximately 400 kilometres long and can also be driven in one day, but again, it is recommended to allow more time to explore the many beaches, fishing villages, and other attractions along the way.
If you are looking to explore the entire island, including the Cape Breton Highlands National Park, it is best to allow at least 3-4 days for your trip.
