Niagara Underground Tour: Power Station and Tunnel Under Falls

The most surprising part of this Niagara tour comes at the end: you descend 180 feet underground through an old power station, follow the route once used by water, and emerge at the base of Horseshoe Falls. It is a clever way to see Niagara from below, not just from the usual railings and boat decks.

I like the Tesla and hydropower story, which gives the falls a practical purpose beyond scenery. I also like the reserved admission, the small maximum group of 22, and the mix of live guiding and self-paced audio exhibits. The drawback is plain: this is a serious walking tour with hills, long distances, and stairs or elevation changes. Wear proper shoes and do not book it if you want a gentle afternoon.

Key points at a glance

• The tunnel is the main event: Walk through the old Tailrace Tunnel to a one-of-a-kind viewpoint at the base of Niagara Falls.
• Tesla gets his due: Learn how his work with alternating current helped make Niagara’s hydroelectric power possible.
• Skylon Tower sets the scene: Use the Glass Elevator and high viewpoint to see the generating stations and water-control system.
• The power station feels hands-on: Original machinery remains in place, with the thrust, brake, and turbo decks explained along the way.
• Expect plenty of steps: The route covers hills and long stretches on foot, so comfort matters more than fashion.
• Your guide shapes the tour: Gord, Deanna, Tim, Kevin, Marni, and other guides have been praised for clear stories, humor, and personal attention.

Why the underground route is worth your afternoon

Niagara Falls is easy to admire and surprisingly easy to misunderstand. You see millions of liters of water plunge over the edge, but the machinery that turns that force into electricity is tucked away behind the scenery. This tour connects the view with the engineering.

The route takes about three hours and begins at 2:00 p.m. at the Starbucks inside or near Skylon Tower. Be careful here: there are several Starbucks locations in the Niagara Falls area. Confirm the exact meeting point, listed as Skylon Tower in Niagara Falls, Ontario, before setting out.

From there, you move through the upper viewpoint, the daredevil stories, the illumination system, Tesla’s legacy, Horseshoe Falls, and the Niagara Parks Power Station. The live guide handles the first part. Once you reach the power station, you receive an audio guide and explore the station and tunnel at your own pace.

That change of pace works well. A guide can explain the big picture and keep the group together, while the audio portion lets you stop, look, and listen without trying to follow a moving speaker.

Skylon Tower gives you the big picture

The tour opens at Skylon Tower, one of Niagara Falls’ best places to get your bearings. The Glass Elevator access is included, so you do not need to arrange a separate visit for the high-level view.

Allow about 20 minutes here. Your guide points out the Niagara Generating Stations and the International Control Dam, where water is diverted for power production. The view helps you understand the arrangement of the river, the falls, and the power facilities in a way that is difficult from ground level.

This is more than a quick photo stop. The upper view shows how close the industrial side of Niagara is to the famous waterfall. The generating stations supply power to a large part of New York state, including about one-quarter of the state according to the tour explanation. You see that the falls are not only a natural attraction. They are also a working source of energy.

The trade-off is weather. The tower viewpoint can be windy, and the views depend on visibility. Still, even a short stop here gives the rest of the tour a useful frame.

Daredevils, barrels, and the human side of Niagara

Before leaving Skylon Tower, you visit the new Daredevil Exhibit, opened in 2025. The stop lasts about 10 minutes and includes admission.

The exhibit focuses on the people who challenged Niagara Falls in barrels and other improvised craft. Seeing the actual barrels adds weight to stories that can otherwise sound like colorful folklore. It also reminds you that Niagara has long attracted people seeking fame, money, or a test of nerve.

This section is brief, so do not expect a full museum visit. Its value is as a change of subject. After hearing about dams, stations, and current, you get the human drama of people choosing to confront the falls directly.

Illumination Tower and the evening light show

The next stop is the Illumination Tower, near the base of the Niagara River. The tour explains how the colored lights transform Niagara Falls at dusk and points out notable figures who have followed this route, including British royalty.

The stop is listed at about 10 minutes, and admission is free. Since the tour begins at 2:00 p.m., the exact light-show conditions depend on the season and the time of sunset. You should treat this as an explanation of the system rather than a guarantee that you will see the full evening display during the tour.

This is a good example of the tour’s wider approach. You are not only looking at the falls. You are learning how people have shaped the experience around them, from power generation to floodlights and public ceremonies.

Tesla’s Niagara connection

At the Nikola Tesla Statue, the guide explains the inventor’s work with water power and hydroelectricity. You also hear about his rivalry with Thomas Edison during the War of the Currents, the battle over alternating current and direct current.

This may be the strongest history stop for anyone interested in science, engineering, or the people behind modern electricity. Tesla can seem like a distant, eccentric figure, but the Niagara connection makes his work concrete. The falls provided a natural test case for producing power on a large scale and sending it over distance.

The guide also covers Tesla’s unusual behavior and personality, which keeps the presentation from becoming a dry technical lecture. Guides such as Gord, Deanna, Tim, Kevin, and Marni have been singled out for making the material clear, lively, and easy to follow. One guide, Deanna, was described as a retired engineer who kept the technical explanations precise and simple. That kind of background can make a real difference when the subject turns to turbines and electrical systems.

Horseshoe Falls from the boardwalk

At Horseshoe Falls, you get a short stop of about 10 minutes on the boardwalk. This is the classic Niagara moment: spray in the air, roaring water, and the powerful curve of the largest of the three falls that make up Niagara Falls.

You have time for photographs, but this is not the main waterfall viewing session of the day. The tour uses the stop to connect the scenery with the engineering story. Your guide explains why Tesla and other inventors saw the falls as a source of usable power, not simply a beautiful spectacle.

You may also see the whirlpool beneath the falls from this area. The view is impressive, but keep your attention on the route and the group. The walking continues from here, and the total distance becomes noticeable.

Inside the Niagara Parks Power Station

The Niagara Parks Power Station was completed in 1905 as the first major power plant on the Canadian side of Niagara Falls. Entering the building shifts the tour from outdoor sightseeing to industrial history.

Original machinery remains inside. Your guide explains the thrust deck, brake deck, and turbo deck, along with how each part supported the plant’s work. The station also includes hands-on training exercises, giving you more to do than simply read signs on a wall.

This is the point where the tour earns its price for many people. Admission is pre-reserved, so you avoid arranging a separate timed entry. More important, the guide explains why the machinery matters. You are not left to stare at enormous metal equipment and guess what it did.

After about an hour in the station, the live portion ends. You receive an audio guide for the power station and Tailrace Tunnel. Some people prefer a guide speaking all the way through. I think the self-paced ending suits this building, since you can spend extra time with the displays that interest you and move more quickly through those that do not.

The 180-foot descent into the Tailrace Tunnel

The underground section begins with a descent of 180 feet through the inner workings of the power station. You then follow the Tailrace Tunnel, the route that carried water away from the plant.

The tunnel is the tour’s most unusual feature. It gives you a physical sense of how water moved through the station, then leads to a viewing point at the base of Niagara Falls. From there, the falls appear from a low angle that you cannot get from the standard overlooks.

A poncho is provided, which is useful because you are close to the spray. The tunnel walk is also long, described in the tour material as roughly a mile. It is not a quick underground corridor followed by a short photo stop. Plan on walking the full route and allow time to pause with the audio guide.

The final view can be spectacular, especially if sunlight creates a rainbow in the spray. You are close enough to feel the force of the water without being on a boat. The setting is also a reminder that the power station was built to control and redirect that force.

Walking demands, timing, and group size

The tour lasts about three hours, but the physical effort is greater than the time suggests. You walk from Skylon Tower toward the power station, cover outdoor paths and hills, move through the building, descend underground, and walk the Tailrace Tunnel.

Several people have found the walking to be the main surprise. The description does identify this as a walking tour and calls for moderate fitness, but you should picture a steady afternoon on your feet rather than a series of short hops between attractions.

Comfortable footwear is essential. Take advantage of pauses when the guide stops to explain a site. Guides have been praised for letting people sit while they talk, but you still need to keep a moderate pace and manage the full route.

The group maximum is 22 people. That is small enough for questions and personal contact, though the feel will depend on the day’s attendance and the guide. Gord, in particular, has been praised for remembering people in the group and making the history feel connected to the individuals listening.

The end point is at 7005 Niagara River Parkway, not back at Skylon Tower. Plan your afternoon around that fact. You will need to make your own way back, and hotel pickup and drop-off are not included.

Is the $81.86 price a good value?

At $81.86 per person, this is not the cheapest way to see Niagara Falls. You are paying for more than a lookout, though. The price includes the local English-speaking guide, the guided walking route, Skylon Tower admission with the Glass Elevator, the Daredevil Exhibit, pre-reserved Niagara Parks Power Station entry, and the Tailrace Tunnel audio experience.

Buying the pieces separately could take more planning and might not provide the same connection between them. The guide also adds value by explaining Tesla, the International Control Dam, and the power plant as parts of one story.

The value drops if your main goal is simply to see the falls from several viewpoints. You can spend less time and energy using direct transport between major sights. This tour makes better financial sense if you want the engineering, the old plant, the tunnel, and the historical context.

The overall rating is 4.6 from 239 ratings, with 91 percent recommending the experience. The praise centers on the guides, the information, the Skylon views, and the underground finale. The repeated caution is the length of the walk. That pattern tells you exactly how to judge the price: the tour offers a lot, but you must be willing to work for it.

Who should book this Niagara tour?

Book it if you enjoy understanding how a place works. The tour suits adults, families with older children, solo visitors, and couples who want more than a standard waterfall photo. Children who like inventions, daredevils, or machinery may find the mix more engaging than a museum-only visit.

It is also a good choice for first-time visitors who want a guide to connect several Niagara sights. You see the falls from above, beside them, and below them, while the power station explains the practical reason this location became important.

Think twice if you have difficulty walking moderate distances or handling hills and a long tunnel. The tour does not provide hotel transportation, and it finishes at a different location from the start. Anyone arriving from the United States also needs a passport to enter Canada.

The tour is offered in English only. Sites can close occasionally, and the route may be changed if that happens. You receive confirmation when booking, and free cancellation is available up to 24 hours before the start time.

Should you book it?

I would book this tour if you want Niagara Falls with a story attached. The best parts are not only the viewpoints. They are the Tesla connection, the preserved machinery, the explanation of how water became electricity, and the walk through the Tailrace Tunnel to the foot of Horseshoe Falls.

Skip it if you want a relaxed sightseeing loop or dislike long walks. For everyone else, the $81.86 cost is reasonable because it combines several paid admissions with a guide who turns separate attractions into one clear account of Niagara’s power, people, and technology.
