Beloved by locals but best visited only on calm days, this secret cove awaits at the end of Kamehameha Rd. At the bottom of the trail, stay left along the cliffs and you'll find a beach with good snorkeling and green sea turtles. Come at high tide.
To find it, take the first right past the Westin, follow it all the way to the end and keep left. From the parking area, you'll see a trail that hugs the cliffs.
