Lawmakers pass bill protecting calm waters, preserving safety of Hanalei Bay

Hawaiʻi lawmakers used part of their time during the 2025 session to pass legislation that will help preserve the safety and natural beauty of the largest bay on Kauaʻi’s North Shore.

Senate Bill 1511 limits the size of vessels allowed in the Garden Isle’s iconic Hanalei Bay in a move to protect its calm waters and ensure it remains a safe space for residents and visitors.

“This bill reflects our commitment to protecting it for future generations, as we prioritize the safety of families and visitors who enjoy its waters every day,” said Hawai‘i Senate President Sen. Ronald Kouchi, who represents Kaua‘i and Ni‘ihau.

Kouchi also noted that Hanalei Bay is a special place, not just for Kauaʻi, but for all of Hawaiʻi.

The bay boasts one of the best beaches in America and views of mystical Bali Haʻi, or Mount Makana, sung about in the 1958 movie adaptation of “South Pacific,” a scene which was also filmed at the iconic crescent-shaped bay.

It also is a culturally significant area for Native Hawaiians.

Ancient Hawaiians used the area’s wetlands for taro cultivation, and the bay held deep spiritual significance. 

Hanalei Bay became a hub for rice production in the 1860s, driven by its ideal growing conditions, and the construction of Hanalei Pier facilitated the transportation of rice throughout the Hawaiian Islands.

The bay’s scenic beauty would captivate Hollywood in the mid-20th century, with movies such as the aforementioned “South Pacific” and also “King Kong” using it as a backdrop.

With Hanalei Bay’s increasing presence on the silver screen, tourism to the area received a significant boost, too.

“Today, Hanalei Bay remains a beloved destination, offering a unique blend of stunning landscapes, rich history and vibrant culture that continues to captivate visitors from around the world,” says the Experience Hawai‘i website.

Concerns about the environmental impact of tourism and development have grown in recent years, the website adds, leading to ongoing conservation efforts to protect bay’s natural beauty and ecological integrity.

The bill passed this session by the state Legislature has the same goal.

It states no vessel longer than 75 feet will be allowed to enter Hanalei Bay, with exceptions made for those operated by federal, state and county agencies.

Hawai‘i Department of Land and Natural Resources will be tasked with defining the boundaries of the bay and enforcing the new rule.

“Our community has spoken loud and clear,” said Hawai‘i House Speaker Rep. Nadine Nakamura, who represents Kaua‘i’s North Shore area, including Hā‘ena, Wainiha, Hanalei, Princeville, Kīlauea, Anahola, Keālia, Kapa‘a, Kawaihau and a portion of Wailua. “Hanalei Bay is a treasure, and this bill is a critical step in preserving the natural beauty of this scenic bay while protecting residents’ access to fishing, swimming, surfing and traditional water activities.”

SB 1511 now is in on the desk of Gov. Josh Green for his consideration.
