Not a lot to do in Halifax on foot except see the public gardens and the maritime museum (both of which are quite nice however). Also they have the Citadel but we didn't really look into that much as it was raining at the time.
If you wanted to see other sights it was necessary to book an excursion.
Actually this stop was Sydney, Nova Scotia which wasn't available to select in the pulldown menu for this review.
Sydney was a very walkable and interesting little town. There isn't a lot to do other than see a few historical homes and shop some but it is very walkable and relaxing.
If you wanted to see other sights again it was necessary to book an excursion.
