Niagara Underground Tour: Power Station and Tunnel Under Falls

Niagara Falls has a secret below the spray. This three-hour walking tour connects the big views with the machinery, inventions, and bold engineering that turned Niagara’s rushing water into electricity. You begin at Skylon Tower, visit the Niagara Parks Power Station, and finish inside the Tailrace Tunnel at the base of Horseshoe Falls.

I like the way the tour joins spectacular viewpoints with real industrial history. I also like having a guide for the outdoor walk, since the stories about Nikola Tesla, George Westinghouse, hydropower, and Niagara’s daredevils give the scenery more meaning. The main catch is simple: you will walk a lot, including hills and long stretches between stops.

The tour costs $81.86 per person and includes reserved entry to Skylon Tower, the Daredevil Exhibit, Niagara Parks Power Station, and the Tailrace Tunnel. With a maximum group of 22, it offers a more personal experience than a large bus outing, though it is not a gentle sightseeing stroll.

Key points before you book

• The tour ends beneath Horseshoe Falls: The Tailrace Tunnel leads to a rare viewpoint at the base of the waterfall, with ponchos provided for the spray.
• Tesla gets a proper place in the story: You learn how his work helped make hydroelectric power practical and how the War of the Currents shaped modern electricity.
• Skylon Tower starts the day high above the river: The glass elevator and observation views help you understand the huge scale of the Niagara generating stations.
• The Power Station still feels like a working industrial site: Original machinery, the thrust deck, brake deck, and turbo deck show how water became electricity.
• The walking is serious: Several people found the distance and hills tiring, so comfortable footwear and moderate fitness are important.
• The final hour is self-guided: Your guide leaves you with an audio guide to explore the Power Station and tunnel at your own pace.

Starting above the Falls at Skylon Tower

Meet at the Starbucks inside Skylon Tower at 2:00 p.m. Take care here, since there are several Starbucks locations in the Niagara Falls area. The meeting point is specifically at Skylon Tower, not simply any nearby café.

The tour begins with reserved admission and glass elevator access. The ride up gives you a useful first look at the Niagara River, Horseshoe Falls, the generating stations, and the International Control Dam. Your guide explains how water is diverted for power production and points out the stations that supply electricity to a large part of New York State.

The view is more than a standard photo stop. From above, you can see the relationship between the falls, the river, the control structures, and the power plants. That wider picture helps explain why Niagara became such an important place in the development of hydroelectricity.

Allow about 20 minutes here. The tower can be windy, so keep that in mind if you plan to take photos or spend time outside the main viewing areas. This part also helps you get your bearings before the walking begins.

The new Daredevil Exhibit at Skylon Tower

Before leaving Skylon Tower, the group visits the Daredevil Exhibit, which opened in 2025. You learn about the people who challenged Niagara Falls in barrels and other homemade craft, and you can see real barrels connected with those attempts.

This is a short stop, around 10 minutes, but it adds a different human angle to the tour. The power station section is about control, machinery, and careful engineering. The daredevil display is about risk, publicity, and the strange pull of the falls.

If you have already seen Niagara’s daredevil stories elsewhere, this may feel like a quick refresher. Still, the actual barrels give the display more force than a simple collection of photographs. It is also a useful stop for families, since the subject is easy to grasp and visually engaging.

Illumination Tower and the show after dark

The next stop is the Illumination Tower near the base of the Niagara River. Your guide explains how the colored light display works and shares stories about famous figures who have passed through this area, including members of the British royal family.

The tour arrives during daylight, so you are not necessarily seeing the evening light show itself. Instead, you learn how Niagara Falls is lit after dusk and why this location matters. Consider this a short storytelling stop rather than a full nighttime attraction.

The 10-minute visit keeps the pace moving, but it also means you should not expect a long presentation. The main value is the added context, especially if you plan to return to see the illumination later that night.

Nikola Tesla’s Niagara connection

At the Nikola Tesla Statue, the tour shifts from general sightseeing to the story of one of the key figures in modern electricity. You learn how Tesla’s inventions used moving water to produce hydroelectric power and how his alternating current system became part of the battle with Thomas Edison over AC and DC.

This is one of the strongest parts of the experience for anyone who likes science, engineering, or overlooked historical figures. Tesla’s work is often reduced to a list of inventions, but here his connection to Niagara gives the story a physical setting. You can see the falls that inspired engineers while hearing how their ideas changed the way power could be generated and sent over distance.

The guide also covers Tesla’s eccentric side. That keeps the subject from becoming too technical, especially for children or anyone who does not usually seek out engineering history.

Guides such as Gord, Deanna, Tim, Kevin, Marni, and Diana have been praised for adding stories and explaining difficult ideas in plain language. Some groups have had retired engineers as guides, while others appreciated guides who connected the technical material with personal stories and local folklore. The quality of this section depends partly on the guide, but the subject itself gives the walk a strong backbone.

Horseshoe Falls from the boardwalk

The group then reaches the boardwalk near Horseshoe Falls. You have about 10 minutes to look over the water, feel the spray, and take photographs.

This stop is brief, so you should not expect a long free period at the falls. Its purpose is to let you see the raw force of the water before entering the Power Station. The whirlpool below and the constant movement of the river make the connection between nature and engineering easy to understand.

The familiar postcard view is here, but the tour does not stop at the usual overlook. The real payoff comes later, when you see the falls from below through the Tailrace Tunnel.

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. Today, the building retains its imposing industrial character, with original machinery and several levels that show how the plant operated.

You spend about an hour here with your guide. The tour covers the thrust deck, brake deck, and turbo deck, explaining what each area did and how water moved through the plant. Hands-on training exercises help make the machinery easier to understand than a display case or a wall of text.

The building is valuable because it shows the work behind the famous waterfall. Niagara is often treated as a scenic stop, but this plant reveals the decisions, machines, and labor needed to turn falling water into usable power.

At this point, your guide says goodbye and gives you an audio guide. The change in format is worth noting. The first part is a guided walking tour with commentary and group pacing. The Power Station and Tailrace Tunnel are then explored independently, giving you more freedom to move at your own speed.

That arrangement works well if you like stopping to read, listen, and take photographs. It may feel less satisfying if you expect the same guide to remain with you through the entire underground section.

Descending 180 feet into the Tailrace Tunnel

The underground portion is the tour’s main reason to book. You descend 180 feet through the interior of the power station, then follow the path where water once flowed through the Tailrace Tunnel.

The tunnel leads to a one-of-a-kind viewpoint at the base of Niagara Falls. You are no longer looking at the water from above or across the river. You are standing near the bottom, with the falls rising in front of you.

The walk through the tunnel takes about an hour, including the descent and the time spent listening to the audio guide. The guide explains the tunnel and the power station’s function as you go. Several people found this section fascinating because it combines a physical journey with a clear explanation of how the plant worked.

You may get wet near the final viewpoint. Ponchos are provided, which is useful because the spray can be heavy. Protect cameras and phones as you would at any close Niagara Falls viewing area.

The tunnel is not a trick or a brief photo platform. It is a substantial part of the experience, and reaching the end requires continued walking. If you are mainly interested in taking a quick picture of the falls, a regular overlook will be easier. If you want to understand the old power plant and see Niagara from an unusual angle, the tunnel earns its place on the schedule.

How much walking should you expect?

This is the most important practical warning. The tour is described as a moderate walking experience, and that description should be taken seriously. You walk between several Niagara Falls locations, go up and down hills, enter the Power Station, descend underground, and continue through the tunnel.

The total distance is not presented as a precise mileage figure, but the repeated feedback is clear: wear comfortable walking shoes and be ready to spend much of the afternoon on your feet. One guide stopped at places where the group could sit during explanations, which helped, but rest stops do not remove the distance.

You should be able to walk at a moderate pace without difficulty. The tour may suit you if you enjoy combining sightseeing with a full physical outing. It is less suitable if you have trouble with hills, long distances, stairs, or extended time standing.

The end point is at 7005 Niagara River Parkway, not back at Skylon Tower. You need to plan for that before starting. The tour does not include hotel pickup or drop-off, and some people disliked being left at a different location from the starting point. Since the route is designed as a one-way walk, arrange your return before the tour begins.

Is $81.86 good value?

The price is reasonable if you would otherwise pay separately for the major admissions and want help making sense of them. It includes Skylon Tower with glass elevator access, the Daredevil Exhibit, reserved Niagara Parks Power Station entry, the Tailrace Tunnel Experience, and audio guides for the final section.

The value also comes from the route. You are not simply buying entrance to a building. You get the connection between the view from Skylon Tower, Tesla’s story, the falls, the old generating station, and the underground tunnel.

The price is less attractive if you only want a standard Niagara Falls viewpoint. You can see the falls from several public areas without booking a guided experience. This tour makes sense when the industrial story and the underground finish matter to you.

A small group of up to 22 people is another plus. It is large enough to keep the tour affordable but small enough for a guide to manage questions and pace. Guides such as Gord, Deanna, Tim, and Kevin have been praised for keeping the history clear, personal, and entertaining.

Who should book this Niagara Falls tour?

I would recommend it to you if you enjoy:

• Hydroelectric power and engineering
• Nikola Tesla, Westinghouse, and the War of the Currents
• Historic machinery and industrial buildings
• Unusual viewpoints of famous sights
• Guided walking tours with plenty of explanation
• Family outings that mix science, history, and dramatic scenery

It is also a good choice for repeat visitors who have already seen the main falls viewpoints. The underground tunnel gives you something different from the usual boat ride or promenade.

I would be cautious if your main goal is a relaxed afternoon. The schedule includes several stops, but the route covers a lot of ground. The final section is self-guided, and the one-way finish means you must arrange your own way back.

The tour is offered in English only. Confirmation is provided at booking, and it operates near public transportation. If you are arriving from the United States, remember that this experience is in Canada and you need a passport to enter the country.

What should you bring?

Wear shoes with good support. This is the single most useful preparation.

Bring a phone or camera for the Skylon Tower view, Horseshoe Falls, and the tunnel exit. The provided poncho helps with spray, but it is still sensible to protect anything that should not get wet.

Allow the full three hours and avoid scheduling another fixed activity immediately afterward. The advertised duration is approximate, and walking groups can move at different speeds.

You can cancel for a full refund if you do so at least 24 hours before the 2:00 p.m. start time. Last-minute changes and cancellations are not accepted under the stated policy. Sites can occasionally close, and route changes may be announced before the tour or at the start.

Should you book the Niagara Underground Tour?

Book it if you want Niagara Falls to be more than a pretty picture. The Skylon Tower view, Tesla stop, original power station, and Tailrace Tunnel fit together into a clear story about water, invention, and human risk.

Skip it if long walks and hills will spoil your afternoon, or if you only want a quick look at the falls. For everyone else, the underground finish is a strong reason to go. Seeing Horseshoe Falls from the base, after following the old path of the water, gives the famous view a fresh jolt of meaning.
