Cultural History of Iao Valley
The Iao Valley is a sacred place and was used as a burial site for Hawaiian family members for centuries. Ancient Hawaiian’s believed that their bones contained their spiritual life force energy. Desecrating or stealing bones could give power, control, and even cause harm to living descendants.
Iao Valley is most famously remembered as the location of the Battle of Kepaniwai in 1790. In an effort to unite the Hawaiian Islands, Kamehameha landed his war fleet on the shores of North Maui while Maui’s Chief, Kahekili, was away on the island of Oahu. Kahekili’s son, Kalanikupule, entered Iao Valley with other Maui chiefs and army members, planning to use Iao Needle as a protective hideout from oncoming forces. He wasn’t aware, however, that Kamehameha had brought Western weapons along with him, including a cannon, which killed many Maui warriors during the battle. The streams of Iao Valley were said to have been blocked by bodies after the battle finished, the reason behind the name Kepaniwai, meaning “the damming of the waters.” While none of Maui’s major chiefs were killed, the damage was done. Chiefess Kalola escaped with her life, accepting Kamehameha’s protection in exchange for the promise of her daughter as his future wife. Kamehameha, after putting down a revolt on the Big Island, returned to Maui in 1894 and prepared to attack Oahu. A year later he defeated Kahekili’s son at the Battle of Nuuanu and solidified his control of the island chain.
INSIDE IAO VALLEY
Within Iao Valley State Park is one of the most popular landmarks – the Iao Needle, which towers over 1200 feet above the valley below. The paved walking trail provides a scenic viewpoint of Iao Needle, crosses a footbridge, and winds through the Ethnobotanical Loop, the park’s beautiful botanical garden. It is filled with many traditional plant species including the ruins of a Hawaiian village and traditional ponds growing taro along the edge of the Iao stream. Morning is the best time to see views of the Iao Needle before the clouds engulf the peaks. Like all nature, your view also depends on the weather.
Iao Valley is the second wettest place in Hawaii, with the Hawaiian island of Kauai being the wettest. The valley receives an average of over an inch of rain per day. Much of this water flows into Iao steam, passing through the town of Wailuku.
One of the most famous legends associated with Haleakalā is the story of the demigod Maui, who is said to have lassoed the sun from its summit to slow its descent, allowing for longer days. This story is deeply rooted in the cultural understanding of the celestial relationship with the Earth. It’s a popular tale that continues to captivate the imagination of both residents and visitors alike.
