Included in the Niagara Reservation State Park and accessible via two bridges, this island has no residents but it is a popular tourist attraction. It is a great place to observe the Niagara Falls, definitely worth visiting not only for the views but also for the peaceful scenery. You can wander around in the woods or take an elevator to the foot of the falls.
