Mahukona Beach Park is a highly unique and intriguing place. Contrary to its name, there's actually no beach. It's a cement laden park along the water that blends naturally beauty and history. The underwater world here is one of the best places on the island to snorkel. Not only because of it's rampant, colorful fish population, but due to underwater archaeological finds. A sort of underwater museum boasts remnants from the plantation and railroad days. Bring snorkel gear and look for the ladder into the water at the north end of the beach. Backing the beach is the near intact structure of the Hawaiian Railroad Company which functioned here for years. Explore the ruins, but be careful. There are shaded picnic areas here but other than that there are no facilities here so bring water. On Highway 270 look for the access between mile markers 14 and 15.
