This is the south side of Waiʻānapanapa State Park; the black sand beach is just off the right side of the image. The sea arch is visible about one-third of the way from the left edge.
This is a five frame panorama stitched together in Adobe Lightroom. If printed out at its nominal size, it would be 68″ x 12″ without lose of detail.
