About 26 years ago, we took the ferry from Portland, ME to Yarmouth and drove around the circumference of Nova Scotia for 2 weeks, staying in bed and breakfasts along the way. We loved it there. Among the things we most enjoyed were the following:
1. Rafting up-river on the Shubenacadie River. Located at the head of the Bay of Fundy, the tidal inrush is so strong that it actually drives you upriver several miles. I can't recall the rafting company, but if you go on-line, you'll find one.
2. Staying in Annapolis Royal. A beautiful historic town. We enjoyed the historic homes and gardens and had the best Digby scallops in a local restaurant.
3. Visiting the Alexander Graham Bell Museum in Baddeck. Parks Canada - Alexander Graham Bell National Historic Site - Alexander Graham Bell National Historic Site
4. Visiting the Glenora Whiskey distillery.
5. A boat tour to see the Puffins. Puffin Boat Tours Cape Breton Nova Scotia - Puffin Boat Tours Cape Breton Nova Scotia
6. Visiting a coal mine under the Atlantic Ocean in Glace Bay. Miners Museum – Glace Bay Nova Scotia Canada
7. Visiting the historic Fortress of Louisbourg.

8. Sunset schooner cruise out of Halifax. We went on a replica of the Bluenose, which is the schooner on the Canadian dime. I don't think it is still doing it, but there are other schooners out of Halifax that will take you out for dinner and drinks. Look online.
9. The Fisheries Museum of the Atlantic in Lunenburg.
