Families planning a visit to Niagara Falls should note the official safety policy: children under 4 years old are not permitted on the Journey Behind the Falls experience. The attraction involves descending through tunnels to observation decks directly behind the massive Horseshoe Falls.
The attraction's website also advises that anyone uncomfortable in small, enclosed spaces should reconsider. For families with children under 4, the nearby Niagara Parks Butterfly Conservatory or the Fallsview Indoor Waterpark offer excellent alternatives.
