There is a small stop on the way to Makapu'u Beach - a scenic point, that showcases views unparalleled to most other lookouts. On the east side of Oahu, there is a highway named Kalaninaole Hwy, which runs all the way next to the beaches and the coasts, passing through various towns. If you follow the scenic route, you will hit Makapu'u Beach, one of my favorite beaches on the east side.
Out of all the beaches I've written about, Makapu'u Beach is probably the one where most of my memories are from, and consequently, where most of my beach photos are from! It's a picture-perfect location.
