Introduction to Havasu Falls: Havasu Falls is known as the largest waterfall in North America. Although its 30-meter drop is not very high, the waterfall is famous for its brilliant and varied colors. The water of the waterfall is blue and contains travertine material. The blue waterfall cascades along the red rocks and into the emerald lake, which is dazzling. There is a small grassy mound at the foot of the waterfall. From here you can look up at Havasu Falls, which is also very interesting.
