Скачать или смотреть Niagara Fall Cruise Ride.

Rainbows at Niagara Falls are very common and beautiful 🌈
Why they happen:
The massive amount of mist created by the falling water acts like tiny prisms. When sunlight hits the mist at the right angle, it bends and reflects to form a rainbow.
Best time to see one:
Late morning to afternoon
When the sun is behind you and shining toward the falls
On sunny days (especially in spring and summer)
Best viewing spots:
The American Falls observation areas
Prospect Point
On the Maid of the Mist boat ride (you can even see double rainbows!)
From the Canadian side, which often gives a wider view
Sometimes you can even see moonbows (rainbows at night) during a full moon.
