Hawaii Island's only working Salt Farm. We are located on the Hawaii Ocean Science & Technology Park and make 100% Pure Hawaiian Salt and Deep Ocean Magnesium from ultra pristine Deep Ocean Waters. We are on a beautiful oceanfront site and are also open daily for Salt Farm Tours where we share what it takes to harvest salt and the process of it, how deep ocean water differs from surface water, the history of our coastline and the Cultural Significance of salt in Hawaii and Hawaii's Salt Traditions.
