Informative and interesting! - This was a last minute decision while visiting the Falls with family up from the U.S. We were a mix of seniors, middle agers, teenagers and a toddler! I had heard good things about it and we were not disappointed. We booked tickets online while we walked over from the Falls. The tour is self-directed. They give you an IPOD sized device to scan at different locations to listen to very interesting facts about this place and its history. We all loved it. Fascinating! And what a different view from the bottom of the falls. Be advised it is probably a 10 min walk from the elevator thru the tunnel to the Falls. The whole museum/tunnel tour probably took us 1.5 hrs but you could easily make it shorter or longer. I would love to do this tour at night when everything including the tunnel is lit up! Everyone talked about this for days after. We were impressed. Enjoy!

Great value, engaging tour - Fantastic tour! Really good value as you get the Skylon tower, power station (and tunnel/viewpoint) and an expert guide all included. The power station was really fascinating and you can linger as long as you want after the tour ends. Our guide Nancy was so friendly, knowledgable and easy to talk to. She really made sure we had a good time. Highly recommended!

Interesting and great addition to our adventure in Niagara Falls! - Nancy did a wonderful tour; she was engaging, friendly and told some interesting stories. We really enjoyed the tour!

Do The Tunnel instead of Journey Behind the Falls! - The Power Station tour was part of our Niagara Park Pass. It was very interesting to see this large power station and have the listening device to narrate as we toured so we didn't have to read all the signs. We then proceeded to the tunnel. Although it is a half mile walk down the tunnel, the view and roar of the falls from this vantage point are worth it! Wish the elevator operator would have mentioned that there were additional spots to activate the listening device for further narration as you were walking, as we didn't realize until almost there so we listened on the way back.

Tunnel is amazing! - Power station is interesting if you're into this mechanical stuff. Best part is the tunnel under the falls! A little bit of a walk but an awesome experience.

Great experience - The tour guide Linda was absolutely amazing. One of the best tour guides I have had. I would tell people to recommend her. Also the tour was amazing.

Amazing! - We took a guided tour. Must book online beforehand. Our tour guide James was super informative. There is so much to look at and they really have everything laid out nicely. The tunnel is amazing but I recommend you wear good shoes as there is a lot of walking. But worth it when you emerge at the end. Pictures do not do it justice.

Phil Rocks! - Phil was an amazing guide! Very knowledgeable about the power station but pretty much all things Niagara as he was raised here. The power station was very impressive and the ending where you get to stand at the base of the falls was very impressive!

This is a must tour! - Deanna was an amazing guide. Her past career as an engineer was a bonus during the tour. You could also tell she really loved giving tours. She was friendly, knowledgable and approachable when we asked questions.

Tour guide never showed and was never heard from again - I am suing - What could have been a memorable experience for me, my brother, and his wife was ruined by a no-show tour guide. I drove SIX HOURS from OH the morning of the event to be at the tour guide’s meeting spot, which for some reason is nowhere near the actual power plant tour itself. The meeting location is huge (easily 10-15 blocks in size) but we were able to find the exact meeting spot (outside the Starbucks on the top section) only HE WAS NOT THERE. No text, no no message, nothing. After waiting a few minutes I texted him via the Viator App, NO RESPONSE ever, just a lame automated response. I’ve called Viator customer support numerous times asking them to have the tour guide contact me and explain what happened, still no response. I’ve used Viator successfully in the past but this experience will make me never use them again. Schedule the tour yourself, save some $, and you will be better for it.
