If you're on the North Shore and want to see one of the natural wonders of the island, stop by the La'ie Sea Arch. It's located off the coast from Laie Point State Wayside, a park that occupies 1-1/2 acres at the end of Laie Point peninsula. It's a great place for fishing, scenic views, and bird watching.
There's a small parking lot at the end of the road. You might see a tour van or bird watching group pull up.
Watch out when you walk out on the peninsula. The rocks are sharp and the waves can break over the edge, but it's good for fishing or bird watching.
There's a plaque on a boulder that explains how this place was created according to ancient myth. Legend has it that La'ie Point and the five islands were formed by a giant lizard, called a Mo'o. The Mo'o killed anyone that intruded into this place. The Mo'o terrorized people until a legendary warrior, Kane, fought and killed the lizard. He took the head, chopped it into 5 pieces, and flung them into the ocean. The 5 pieces formed the 5 islands we see today.
The names of the islands are Kihewamoku, Mokuaula, Pulemoku, Mokualai, and Kukuihoolua. All the islands are protected bird sanctuaries.
The Sea Arch is on the island of Kukuihoolua. Originally the arch was a cave, only visible from sea. In April of 1946, a tsunami crashed into the cave and broke the back wall. This formed what we see today, the Sea Arch.
