Hanauma bay was a recreational area used by Hawaiian nobility, including King Kamehameha and Queen Ka‘ahumanu, who fished, entertained visitors, and sponsored games there. The Bay was also used as a layover and as a navigational lookout point, since the waters between Oahu and Molokai are at times difficult.
This beautiful place is where archeologists found fishing tools and other indications of human presence in the early days even though there was no fresh water for miles around.
Today this place is sought by snorkelers, beach combers, and sun bathers who want to enjoy the rich history and pristine waters that the bay offers. Snorkelers are presented with an assortment of colorful tropical fish to include the Hawaiian State fish (Humuhumunukunukuapua`a), and the majestic Hawaiian Green Sea Turtles that glide through ancient corals nested in the crystal clear water. This is a place you must see if visiting the island of Oahu. Arriving there prior to 6am will benefit in free parking and no park entrance fee as an early bird special. The park is very popular and becomes very crowded after about 9am.
With spectacular view of the bay you are also visually privy to the beauty of KoKo Head. The Koko Head Crater Trail is a hike for another day if you got the family but definitely should be one on your bucket list of hikes to do while visiting Oahu. Koko Head Crated Trail is a hike that will make you ask yourself "Why am I doing this again?" but well worth the sweat and sore muscles. Here are a few from my trip up Kokohead Trail last February.
