Beaches and Parks
Waves generated by winds hundreds of miles to the north in the Pacific, perfect reefs, and typically off-shore winds combine to create the beaches of the North Shore, world recognized as the Mecca of Surfing. There are very beautiful beaches along the coast, providing peaceful places to relax, challenging surf breaks for professional surfers, snorkeling, scuba diving, fishing, and everything in between. The ocean is generally calm during the summer months and the large swells of waves come in the winter.
If you're unsure about the safety of entering the water at any beach, consult a lifeguard. You can get more information on being safe at Hawaii's beaches from the Ocean Safety and Lifeguard Services Division.
Laniakea
Laniakea- Located in the area between Haleiwa and Waimea Bay known as Kawailoa, Laniakea Beach was named by a group of surfers in the 1950's, who saw a nearby house with "Laniakea" written on it, which literally means "wide sky" in Hawaiian language. This beach is famous for its long right surf break and the Hawaiian Sea Turtles which habit the shore, grazing on limu (seaweed) and entertaining visitors amazed by these majestic yet endangered animals.
