The route measures 298 km (185 mi) in length and completes a loop around the northern tip of the island, passing along and through the Cape Breton Highlands.
The route is named after the explorer John Cabot who landed in Atlantic Canada in 1497, although most historians agree his landfall likely took place in Newfoundland and not Cape Breton Island. (Premier Angus L. MacDonald attempted to re-brand Nova Scotia for tourism purposes as primarily Scottish and, as part of this effort, created both the names Cape Breton Highlands and Cabot Trail). Construction of the initial route was completed in 1932.
The northern section of the Cabot Trail passes through Cape Breton Highlands National Park. The western and eastern sections follow the rugged coastline, with views of the ocean. The southwestern section passes through the Margaree River valley before passing along Bras d'Or Lake.
The road is internally referred to by the Department of Transportation and Public Works as Trunk 30. The Trunk 30 road named the "Cabot Trail" loops from Exit 7 on Nova Scotia Highway 105 at Buckwheat Corner to Exit 11 on Highway 105 at South Haven. The scenic travelway known as the "Cabot Trail" includes all of Trunk 30, as well as the portion of Highway 105 between exits 7 and 11.
