Star Caves (also known as Keau Corners) is one of the most unique and beautiful reef dives on Oʻahu’s west side. Named for its star-shaped lava formations, this site features swim-throughs, natural arches, and spacious caverns that make it a favorite for topography lovers and underwater photographers.
You’ll cruise over dramatic lava landscapes, duck through lava tubes, and drift past walls teeming with life. Turtles are almost always around, eels poke out from crevices, and schools of fish swirl through light-dappled corridors.
At times, even rare nudibranchs and Hawaiian monk seals make an appearance.
This is a great second dive on our west-side charters — relaxed, scenic, and full of visual treats.
