Hanalei National Wildlife Refuge · American Heritage River (1998) · Endangered Hawaiian Waterbird Habitat

The Hanalei River drains the Hanalei Valley on Kauai’s North Shore — the lush taro-field landscape that inspired the song “Puff the Magic Dragon.” The river runs 16 miles from the Waiʻaleʻale headwaters down through the Hanalei National Wildlife Refuge before reaching Hanalei Bay, one of the most photographed beaches in the world. The valley produces over half of all the taro grown in Hawaii, and the river’s slow-moving lower reach is a popular flatwater paddle through working agricultural land protected as critical habitat for endangered Hawaiian waterbirds.
