Maniniowali Beach (Kua Bay)
Kekaha Kai State Park, Kailua-Kona, HI 96740
The north section of Kekaha Kai State Park, just north of Kona Airport — vast golden sand, jewel-blue water, and a black-lava backdrop. Calm summer water for swimming and snorkeling along the reef edge; winter shore breaks turn body-surfable. Almost no natural shade — bring an umbrella.
