Diving on seamounts and marine pinnacles
Exploring vertical marine terrain such as seamounts and pinnacles and what distinguishes them as exceptional dive sites.
Marine pinnacles and seamounts are among the most exciting dive sites because they gather different kinds of life in a tight space.
What pinnacles and seamounts are
Pinnacles are coral rock masses that rise from the seabed. A seamount is a rocky hill that protrudes from the bottom to approach the surface. Both concentrate feeding currents and large fish around them.
Why they attract large marine life
Upcurrents around this terrain lift nutrients from the depths, which attracts small fish, then larger ones to hunt them, and thus a food chain forms at one point.
Tips for diving in these areas
- Expect currents around pinnacles and seamounts and plan for them
- Approach from the side facing the current, then circle the pinnacle
- Watch above as well, because large fish hover over these areas
Best times to visit pinnacles
Dawn hours and late day, when marine life is active at these areas, give the best experience.
A single pinnacle may hold more diversity than kilometers of flat reef.
