I did a camping trip into the Maritimes a zillion years ago back in my early 20s. Bay of Fundy, Prince Edward Island and part of the Cabot Trail in Nova Scotia. I've been wanting to go back ever since.
Highlights on this trip include Bay of Fundy, as well as Halifax and Sydney NS. A couple arraigned tours, mostly a few hours walking around the port areas. We do have a trip planned to Fort Louisburg outside Sydney. Part of my interest in historic forts.
