If you prefer a self-guided tour of Saint John, you have two options: explore downtown and a few neighborhoods or take a harbor walk leading to the famous Reversing Falls. This travel guide provides recommendations for both. It starts on Water Street, your disembarkation point from a cruise ship, and leads you along the waterfront. The city tour begins at photo number 18. If you are energetic, there should be plenty of time to see everything in one day.
