Hanalei Valley Lookout offers one of the most famous views on Kauai. The valley is one mile wide and six miles long. Most of the taro grown in Hawaii is grown here. On the valley floor is a one-way truss bridge built in 1912. The bridge was damaged by a tsunami in 1957, and subsequently reinforced. Legend has it that the rainbow came to Hawaiian Islands from the bluffs just beyond the valley when a piece of brightly colored kapa cloth was thrown into a pool below Namolokama Falls, and its colors arched up in the mist.
