Kohanaiki, located just north of Kailua Kona, is my new favorite park here on the island. It’s the home of a popular surf break known as Pine Trees. There’s a long, sandy beach backed by trees offering shade (not pine trees though). It’s an historic area, too, and at the south end of the park is a variety of old Hawaiian structures as well as a garden featuring native plants.
