Diamond Rock

A Dive into Portofino’s Underwater Wonders

Why is it called Diamond Rock? This dive site gets its name from a striking limestone clast embedded in the towering wall of the Portofino promontory, resembling a precious diamond set in stone. With vibrant marine life, dramatic rock formations, and breathtaking visibility, Diamond Rock is a must-dive site for enthusiasts of all levels.

🔴 RED ROUTE – Depth: Up to 40m

After a pre-dive check and bubble check, we descend to -16 meters near the buoy’s anchor point. Our journey begins by finning southeast, following the landslide down to a maximum depth of -40 meters.

What you’ll see:

  • Huge brown groupers and snappers curiously following divers
  • Octopuses, moray eels, conger eels, and lobsters hiding in the rocky crevices
  • The first red gorgonians appearing below -25 meters

At the maximum depth, we continue along the left wall, gradually ascending through a series of boulder formations, creating unique swim-throughs. After about 20 minutes, we begin our return journey at -14 meters, where two tall pinnacles with a passage between them mark the approach to the chain.

Before surfacing, we explore a massive boulder at -10 meters to -5 meters, perfect for spotting more marine lifewhile completing the safety stop.

🟢 GREEN ROUTE – Depth: Up to 18m

Following the pre-dive check, we descend along the buoy chain and arrive at -16 meters. With the wall on our left, we explore the rocky slope, maintaining a maximum depth of -18 meters.

What you’ll see:

  • Octopuses, nudibranchs, starfish, anemones, scorpionfish
  • Large groupers, snappers, sea breams, and corvine
  • Occasionally, a school of tunas hunting in the blue!

As we turn back, keeping the wall on our right, we ascend to -14 meters where the twin pinnacles signal the approach of the chain. The dive ends near the large boulder at -10m to -5m, where we complete the safety stopbefore surfacing.
