About Yap Caverns
This southern-tip reef on Yap is reached by boat and combines swim-through caverns, reef walls, and open hard-coral sections. It is known for dense macro life, but the broader site can also turn up sharks, rays, and other large visitors. Plan on calm seas, a guided dive, and careful buoyancy through the overhead sections.
