The observation deck was built here in the United States, because the landscape here is not as good as the Canadian side, so it has to be extended to see further, but because there is often fog on the waterfall, so actually look there. It is not very clear either.
This ticket is the same as Maid of the Mist, so you can enjoy the Rainbow Bridge in the process of queuing.
This tower is also relatively tall, and there are not many tourists, and the tickets are not expensive. Just line up for a while and you can go up to the tower. You can see the waterfall in the distance, and it feels right under your feet!
This place is the best place to see the waterfall, so be sure to go early
