The tunnels were originally excavated in the late 1880s for a hydroelectric power project.
The bedrock behind the falls is primarily shale and limestone, which has been eroded over thousands of years.
The roar of the falls inside the tunnels reaches approximately 100 decibels.
The water flow passing through the Horseshoe Falls is regulated by international treaties to maintain its appearance while optimizing power generation.
The mist generated by the falls at this location creates a microclimate that allows unique lichen species to grow on the tunnel walls.
Journey Behind the Falls consists of a series of tunnels and outdoor observation decks located directly beneath and behind the Horseshoe Falls in Niagara Falls, Canada. Visitors descend 125 feet via elevator to access the 130-year-old tunnels carved through the bedrock. Two outdoor observation decks provide views from the base of the waterfall, allowing visitors to see the 2,800 cubic meters of water per second falling overhead. The complex features portals cut through the rock, offering a perspective from within the cascading water. The attraction is managed by the Niagara Parks Commission. Guests receive a complimentary biodegradable rain poncho to handle the intense spray and mist encountered at the decks. Access to the observation area is facilitated by a network of tunnels that extend 150 feet behind the cataract.
The lower observation deck directly beside the falling water curtain for the most dramatic angle.
Wear waterproof footwear, as the observation deck floor is perpetually covered in mist and water.
Protect your electronics and cameras with waterproof cases, as the spray is heavy regardless of the weather.
Visit the lower deck for the most intense auditory experience and the closest view of the falling water.
Do not attempt to walk onto the rock ledges outside of the fenced observation areas due to high-velocity water and extreme slipperiness.
Open year-round, though the lower observation deck may be closed periodically during winter months due to ice accumulation.
Keep the provided rain poncho on while on the observation decks to prevent water damage to clothing and surrounding walkways; stay within marked tunnel boundaries.
