Coconut Island, or Moku Ola is a small island in Hilo Bay, just offshore from Lili'uokalani Park and Gardens, in Hilo, off the island of Hawaii. It is a small park, and is connected to the main island via a footbridge. The island includes a large grassy field, picnic areas, restroom facilities, and a few tiny sandy beaches.
A popular recreational activity is to jump off the tower into the waters of Hilo Bay.
The name Mokuola translates as "healing island" or "island of life" from the Hawaiian language. Moku meaning "island" and ola meaning "life." It was the site of an ancient temple dedicated to healing.
