What You See Down There

The Physical Facts

• An elevator descends about 38 metres (125 feet) through bedrock
• Two tunnels run roughly 46 metres (151 feet) in behind the Horseshoe
• The tunnels are about 2.4 metres wide and 2 metres high
• They end at two openings in the rock face: the Cataract Portal and the Great Falls Portal
• A lower observation deck sits beside the base of the falls, closed in winter

What It Is Actually Like

Manage your expectations in one direction and raise them in another.

Lower them on the view. At the portals you are not looking at a waterfall. You are looking at the back of one — a moving wall of green-white water a metre or so away, filling the opening completely. Photographs of it are mostly indistinguishable from photographs of any large volume of falling water.

Raise them on everything else. The noise is the thing nobody prepares you for: a continuous physical pressure rather than a sound. The tunnels are cold, wet, dimly lit and completely unlike the manicured attraction the surface suggests. The spray behaves like weather.

The lower deck, when open, is where the actual view is.

The 1889 Tunnels

Most visitors assume this is a modern attraction. The first tunnels opened in May 1889 — a 150-foot passage cut behind the falls, unlit, with guides carrying lanterns to walk visitors down to the open portal.

That is a remarkable thing to have attempted in 1889, and knowing it changes the walk. The current tunnels are a descendant of that idea rather than a new one.

The redevelopment scheduled for spring 2027 reopens a historic tunnel that is currently visible but not accessible — which is to say, part of that older network.

Practical

• The poncho is provided and you will use it.
• Shoes with grip. The floor is permanently wet.
• Phones in pockets at the portals unless you are prepared to dry them.
• Twenty to thirty minutes for the whole thing.
