The Legend of Twin Rocks:

"Legend has it that one day, a chief of the village spotted many canoes with sails heading shoreward in their direction. Fearing an attack, the chiefs and village elders held a council to determine a course of action. They decided to build a reef to prevent a landing on their beaches. Not having the means to complete the task quickly enough, they asked for two young lovers to be the guides and protectors of the village by giving their lives. Two willing individuals were found.

That night a decree was sent to all who live at Kahali'i to remain indoors from sunset to sunrise without making any light or sound, on penalty of death. In the light of the new day, everyone went down to the shoreline where they were amazed to find the lovers gone, and in their place the gigantic rock formations at the entrance of the bay, attached to each other, as if on guard.

The chief informed the people that no canoe could not pass the treacherous currents swirling around the rocks unless allowed to do so by the guardians. The lovers and their offspring still stand today, sentinels at the end of the bay."
