Diamond Rock: Top Diving Spot in Saba

The Legend and Origins of Diamond Rock

Legend has it that Saba’s dramatic volcanic spire Diamond Rock earned its name when a jilted sailor threw his amour’s engagement ring onto the rock as he returned to sea. The ring apparently remains there, awaiting discovery.

A more believable origin is attributed to the adjacent submerged series of pinnacles named Man O’War Shoals, which ripped the bottom from many ships which sailed between Torrens Point and the peaks of Diamond Rock.

Our boat used a mooring positioned between these two sites, giving only a 50m swim to each. Inevitably we chose to explore first the one we could see from the boat – Diamond Rock.

Even 50m at the surface is hard work when you’re towing two camera systems, but the effort was forgotten as we submerged on the east side of the largest pinnacle.

First Dive Impressions: Lava Walls and Pinnacles

The sheer face plummets with barely a break to 32m, and our first impression was of a profusion of colour on the lava walls.

The next was of movement from the numerous fish attracted to the shelter of this isolated reef. Near the surface, horse-eye jacks patrolled the spire, while a little deeper schoolmaster, yellow-tailed and blue-lined snappers gathered in groups close to the reef.

In the cracks and overhangs, small schools of black-bar soldierfish hung out. We headed for the bottom in the hope of sighting reef sharks and eagle rays.

Incredible Marine Life Encounters

The sharks were there and briefly inspected us before departing into the blue, and in lieu of eagle rays we found several southern sting rays, which rose majestically as we approached to follow the sharks.

Circumnavigating the main spire, it became clear that there were four pinnacles here, two breaking the surface, two submerged.

This arrangement forms several deep dissecting gullies with dramatic sheer walls carpeted with sponges, gorgonians, soft corals and dozens of colourful anemones the size of dinner-plates.

Within these were both symbiotic black and yellow blennies and gaudily patterned pistol shrimps. From fissures in the reef, green and black and white snowflake moray eels peered. The topography of the spire offers the perfect dive profile as you spiral upwards around it.

Reaching 6-8m on the west face, where the submerged pinnacles top out, the water movement can become a little more exciting, as the occasional heavy Atlantic swell finds its way from the open ocean on the far side of the island.

Unwary divers can be picked up and punched through the gap between the two largest pinnacles – fun, but not for the faint-hearted! At this depth you will likely encounter one of several large lone barracuda, able to hold station regardless of conditions.

It will patiently give you the eagle eye and a fearsome grin as you creep closer. We surfaced anxious to know if the neighbouring reef was as good.

A Calmer Adventure at Man O’War Shoals

The only indication of the presence of Man O’War Shoals is a white buoy attached to the highest point at 5m. It has a very different feel from Diamond Rock, even though some geological features are similar. The seabed bottoms out at 24m.

Two large interconnecting pinnacles reach the shallows and two much smaller outcrops rise some 8m from the seabed.

When the swell washes through the gap at Diamond Rock you’ll find a more relaxing dive at Man O’War Shoals, though our first experience of it was no less exciting. As we approached the rock, a frisky reef shark shot between us and headed for a small cave between the peaks.

We followed, but he showed signs of agitation at having his exit blocked, so we retired gracefully and continued our dive with a friendlier hawksbill turtle, which seemed determined to show us another cave where a small nurse shark resided.

The coral and sponge growth was again lush, but with far healthier gorgonian colonies away from the sometimes violent swells of Diamond Rock. Every sort of reef fish competed for meals, the oddest being the boxfish, trunkfish and filefish, all trying to feed through pursed lips.

Among the thickets of marine life the smaller fish species sheltered, and we noticed hawkfish, blennies, gobies and a variety of crustaceans, often camouflaged with bits of sponge and soft coral for protection.

The largest were the spiny lobsters. These had us thinking of our stomachs, though in a marine park, forget it! Their immunity leads to bold behaviour from the lobsters, which stroll about in the open, sometimes shadowed by trumpetfish waiting for scraps.

Up in the shallows there were large barrel sponges on the south side of the pinnacles. Close inspection as we ambled upwards revealed dozens of tiny secretary blennies, appearing to chatter to each other in the typing pool as they darted in and out of their burrows to feed on passing plankton.

We finished our dive on a safety stop atop the rocks, watching a school of Atlantic spadefish cruise in squadron formation out of dancing shafts of light thrown by the lowering sun.
