Just north of Hamoa you’ll come across a small remote beach called Koki Beach. Koki Beach has reddish-gray sand and is often un-crowded. Chances are you get it all to yourself on weekdays. It is a great place to sit and relax in the sun and have a picnic on the beach, or just take advantage of the roadside parking and enjoy the scenery.
There's a small island just offshore topped with coconut palms swaying in the breeze. At the northern end of the beach you can explore the lava formations and tide pools at the bottom of towering red cliffs. This beach does not provide the gentlest environment for swimmers. The constant trade winds on this side of the island make the ocean very rough.
It does have a sandbar that extends several yards into the ocean making it safe for wading as long as you stay in knee-deep water. Venture out too far and dangerous waves and currents will suck you out to sea. On a happier note, it is a great place for body boarding. You will find it exciting to play in the shore break if you are a strong ocean swimmer.
