2 areas I really liked are the very northern part of Cape Breton - at least 2 days of walking.
& the Fortress at Louisbourg, at least one day of visiting many parts of that community and finding out what made it so special in the colonial era.
Cabot Trail - well I used to live within 1.5 hours of Gros Morne National Park, Newfoundland. & that has at least 100 x as many places special to Planet Earth over the NS park. You see in the Gros Morne Days the locals insisted on being a part of the park and still are. The Feds insisted on taking local settlements away when they set up the Cape Breton Park.
Though, yes, Cape Breton has scenery and music.
