Hanakapi’ai Falls--located on the island of Kauai, Hawaii. Its not a very known waterfall mainly because in is hidden. To get to the fall you need to walk through a trail that is around 2 miles long. On the bright side the trail starts at a beach, so if you don’t like trails you can still have a fun day. The fall is 300 ft tall making it a larger fall than Niagara falls, so if you do think about diving off you might want to rethink.
Horsetail Fall, California: This incredible sight celestial happens in a flash at sunset in mid-February at Yosemite National Park — if the winter weather cooperates. On those days the setting sun illuminates one of the park’s lesser-known waterfalls known as Horsetail Fall, so precisely that it resembles molten lava as it flows over the sheer granite face of El Capitan.
