We went to the beach across the street from the West Hawaii Veteran's Cemetery for the afternoon. It is called Kua Bay Beach Park, at the Manini'owali section of the Kekaha Kai State Park. This is a fantastic beach to lay out on and play in rolling waves.
Another beautiful beach panorama.
It was a little overcast, but this beach was fantastic.
There weren't very many waves, but just a nice roll of water to play in.
I would definitely recommend going here.
