What structure offers the greatest visual impact in Niagara Cave?

The Cathedral Room stands out as the structure that offers the greatest visual impact in Niagara Cave due to its impressive size, unique formations, and beautiful natural features. This expansive chamber is characterized by high ceilings and dramatic stalactites and stalagmites, creating an awe-inspiring atmosphere that captures visitors' attention. The intricate details and scale of the formations amplify the sense of wonder and majesty within the cave, making it a highlight of any tour.

While stalagmites and flowstone are visually appealing and contribute to the cave's overall beauty, they do not match the sheer grandeur and striking presence of the Cathedral Room. Natural bridges, on the other hand, are fascinating geological formations but often lack the overwhelming visual spectacle found in larger, open chambers. The combination of size and natural artistry in the Cathedral Room makes it a focal point for visitors, thus providing the greatest visual impact in Niagara Cave.
